Earth:<br />

the water<br />

planet<br />

Water<br />

is a significant feature of our planet; perhaps one<br />

of its most distinguishing characteristics. But just because<br />

water is prominent on Earth does not mean that<br />

fresh water supplies are endless. Fresh water is actually<br />

quite limited. Humans use a lot of it – so much that<br />

we, as a species, have come to literally dominate the<br />

planet’s water cycle, crowding out other species and<br />

putting ourselves in jeopardy. For the benefit of future<br />

generations, we need to develop an entirely different<br />

relationship to the water cycle – one of vastly increased<br />

efficiency and long-term stewardship.

How much water do humans need?<br />

A commonly used estimate of the average amount of water<br />

ingested by a person in a day is two litres. This means that<br />

the average person ingests 730 litres per year. The entire<br />

human population thus takes in about 5.2 trillion litres, or<br />

5.2 cubic km. Imagine a huge cube of water that's a little<br />

under two km wide, two km deep and one and a half km high<br />

– that’s how much water humanity drinks and eats in a year!<br />

Although, when you consider that Peru and Bolivia’s Lake<br />

Titicaca contains 893 cubic km, America’s Lake Superior<br />

contains 11,600 cubic km, and Russia’s Lake Baikal – the<br />

biggest - contains 23,615 cubic km, you realise that humanity’s<br />

drinking water needs are just a drop in the bucket compared<br />

to even the little portion of the Earth’s water that is fresh. So<br />

why is it that we have a water problem? Surely all we need is<br />

a small lake?

We use so much water! Where? The answer involves agriculture and<br />

industry. By comparison, all our showering, laundry-washing, lawnwatering<br />

and other individual water consumption accounts for a<br />

relatively modest share of annual per-capita water use.<br />

The fast-turning<br />

waterwheels of<br />

agriculture and industry<br />

Agriculture is number one<br />

Agriculture, which uses over two-thirds of all freshwater<br />

withdrawals, occupies 14 out of the top 15 sectors of production<br />

in terms of litres per unit of economic value generated.<br />

Number 1 is cereal grain production, followed by cotton,<br />

sugar, tree nuts, and fruit. In fact, the only industrial use in<br />

the top 15 is energy production and distribution at number 7.<br />

In other words, most of the water that humanity uses<br />

goes to produce food, fibre, animal feed, and to some<br />

extent fuel – through agriculture. It’s interesting, to discover<br />

that producing a kilogram of beef requires thousands of<br />

litres of freshwater and a cup of coffee or a soft drink well<br />

over 100 litres.

Industry drives towardS greater water<br />

efficiency<br />

In industry, water can be used in a vast range of ways: as a<br />

solvent, a coolant, a high-pressure cleaning tool, a cleanser,<br />

a hydraulic fluid, and more. Around a decade ago, when water<br />

prices were lower and awareness limited, water was used in<br />

industrial processes with little restraint. Today, we are more<br />

careful, with water prices and awareness both rising steadily.<br />

Many multinational corporations have developed a corporate<br />

water strategy, which includes a mixture of technical efficiency<br />

initiatives, supply assurance and stakeholder relations. Car<br />

production for instance may not come to mind as a waterintensive<br />

industry and yet from 2000 to 2011, this approach<br />

enabled one renowned car manufacturer to reduce water<br />

consumption from 9,8 to 4,7 cubic metres per car produced<br />

globally and achieve a total annual reduction of 60%, or<br />

almost 38 million cubic meters. And Facebook just started<br />

reporting the water it uses indirectly through the lifecycles<br />

of the energy it purchases.<br />

Tetra Pak Processing rises to the challenge<br />

Operating in the food processing and packaging business<br />

means a lot of water consumption to keep the business<br />

going, both technically and hygienically.<br />

Tetra Tebel Alfomatic cheddaring machine, rinse water can now be<br />

recovered and recycled.<br />

Tetra Pak is constantly working hard to find innovative<br />

solutions to help its customers save water and improve<br />

their production processes. For instance, thanks to the novel<br />

filtration unit available for the Tetra Tebel Alfomatic cheddaring<br />

machine, approximately 40% of the total water it uses can now<br />

be recovered and recycled during all of the various rinsing<br />

phases. In the case of one large producer in France, where<br />

some 1,1 million litres of milk are processed to make<br />

mozzarella cheese, this translates in to around a saving of<br />

50,000 litres of water every day.<br />

That’s a lot of water!<br />

Saving water in the land of the Nile<br />

Innovations from Tetra Pak Processing are saving Faragalla in Egypt<br />

600,000 litres of water per day – according to FAO, that's equivalent<br />

to the daily water requirement for around 200,000 people.<br />

The depletion of the aquifers<br />

In many parts of the world, expanding human populations<br />

and agricultural production rely on “fossil water” - water that<br />

has accumulated over millennia in aquifers deep underground<br />

– and this is rapidly being depleted as wells pump it<br />

TETRA PAK <strong>Magazine</strong><br />

to be expected. The USA however, is home to less than 5%<br />

of the human population yet extracts nearly as much water<br />

as the other two. The reason? Large agro-industrial production<br />

and a huge food export base that supplies countries in almost<br />

to the surface.<br />

every part of the globe. In short, providing food to communities<br />

worldwide is taking its toll on the once abundant underground<br />

Examples of aquifer depletion can be seen in the USA, India,<br />

water resources. And yet, ironically, one of the greatest<br />

and China. India extracts more water than any other nation<br />

problems of fossil water depletion is the negative effect it is<br />

from wells and aquifers, and China is not far behind with the<br />

having on global food supply. Grain yields are falling all over<br />

vast bulk being used for agriculture - often rather inefficiently.<br />

the world as a consequence of shrinking aquifers.<br />

Each of these nations has about one-fifth of the world’s<br />

population, so their high water extraction rates are probably<br />

9<br />

What is an aquifer?<br />

An aquifer is an underground layer of water-bearing permeable rock or<br />

unconsolidated materials (gravel, sand, or silt) from which groundwater<br />

can be extracted using a water well. They can occur at various depths.<br />

Those closer to the surface are likely to be used for water supply and<br />

irrigation, and also more likely to be topped up by the local rainfall.

A key goal here is to use less water by putting it only where it’s<br />

needed and drip irrigation is one good measure.<br />

Peak water – a threat to our<br />

future?<br />

Unlike fossil fuels, fossil water is a<br />

renewable resource. However, given<br />

the limited technology we have at<br />

hand today, we could be approaching<br />

the point where the extraction of fossil<br />

water is reaching its peak; it may never<br />

yield as much again. So the question<br />

is, what happens next?<br />

Some ideas that offer a<br />

way forward:<br />

• Greater agricultural efficiency<br />

The goal here is to use less water<br />

by putting it only where it’s needed,<br />

minimizing the amount of water that’s<br />

lost to evaporation, consumption by<br />

weeds, leakages and other such losses.<br />

Measures include drip irrigation,<br />

deeper mulching/compost application,<br />

greenhouses and hoop houses, as well<br />

as introducing hardier crops.<br />

• Dryfarming in California<br />

One small scale, but shining example<br />

of efficient water use is at this vineyard<br />

in Santa Barbara County, California.<br />

The grapes at Condor’s Hope are<br />

nurtured solely by rainwater; no other<br />

irrigation methods are used.<br />

Dryfarming means planting droughtresistant<br />

crops and maintaining a fine<br />

surface soil or mulch that protects<br />

the natural moisture of the soil from<br />

evaporation.<br />

• Reforestation<br />

Planting trees allows soils to retain<br />

more rainwater and recharges surface<br />

and shallow ground water supplies.<br />

Reforested areas also maintain higher<br />

air humidity, which assists nearby<br />

agriculture. Conserving and improving<br />

soils and preventing erosion go hand<br />

in hand with this, as they reduce runoff<br />

and increase the ability of land to<br />

grow forests too.<br />

Dryfarming means planting drought-resistant<br />

crops and maintaining a fine surface soil.

• Forestry in a treeless land<br />

The Icelandic Forest Service defines<br />

itself as working on “Forestry in a<br />

treeless land.” The IFS explains that it<br />

is not the Icelandic turf or climate that<br />

is behind its treelessness. Rather, it is<br />

a history of poor land-use decisions.<br />

To combat these conditions, the IFS<br />

planted more than 4 million seedlings<br />

during the 1990s, an effort they have<br />

expanded to include direct seeding,<br />

the use of tree nurseries, and the<br />

reintroduction of native birch.

Did you know that by 2025<br />

Water withdrawals are predicted to increase by:<br />

• 50 per cent in developing countries<br />

• 18 per cent in developed countries<br />

• Repairing leaky water mains<br />

Recently, the World Bank estimated that as much as 60% of<br />

all water withdrawn by humans is lost due to leaky pipes.<br />

So, repairing and in some cases modernizing the water<br />

infrastructure would make a big difference.<br />

• Demand-side management<br />

Managing our water consumption in settled areas through<br />

public information campaigns and selective pricing could<br />

both reduce waste and encourage smarter practices. These<br />

include planting indigenous vegetation that is suited to the<br />

local climate, washing cars less often, putting low-flow<br />

nozzles in showers and sinks and using low-flow toilets.

Thirsty for change<br />

Withdrawing water from fossil aquifers, shallow ground water wells, and surface waters are currently the main ways<br />

in which we obtain water for human populations, agriculture, and industry. Other sources such as desalination<br />

and rainwater harvesting are so far negligible.<br />

In many parts of the world water withdrawals are sustainable,<br />

and of course the distribution of water stress around the<br />

world is very uneven; the world is divided into the “water<br />

haves” and “water have-nots”.<br />

Many inventors, companies, university researchers, government<br />

agencies and others are dedicating enormous time and<br />

resources to solve the global water problem. Their efforts<br />

appear to be paying off. Here are just a handful of the many<br />

ideas we came across in our research.<br />

Clean drinking water for more than<br />

300 people a day!<br />

The inventor Dean Kamen, famous for many innovations<br />

including the Segway two-wheeled self-balancing vehicle,<br />

has been dedicating his creative energies to the pursuit of<br />

clean water for the world’s poor. His design firm, DEKA, is<br />

developing a water purifier based on their experience with<br />

dialysis technology. Kamen notes that at least half of all human<br />

diseases in the world today are caused by water-borne<br />

pathogens. Bad water is responsible for the deaths of over<br />

2 million people a year – most of them children.<br />

Kamen’s Slingshot produces pure, drinkable water from<br />

literally any source, including salt water, chemically contaminated<br />

water, and water full of biological parasites. It is designed to<br />

operate for five years with no expert maintenance, and comes<br />

in a sealed plastic box that can withstand rough conditions.<br />

Energy comes from a Stirling engine burning a range of<br />

possible combustible fuels, including wood and even cow<br />

dung. Water is purified using vapour compression distillation.<br />

One unit has the capacity to produce 1,000 litres of drinking<br />

water per day – enough to sustain 300 people.<br />

DEKA is rolling this innovation out slowly. Slingshots are<br />

being shipped mainly to Africa and South America, whilst<br />

a consortium of global companies are working together to<br />

install 2,000 Slingshots in rural<br />

communities in 20 different<br />

countries by the end of 2015.<br />

We should be hearing more<br />

about the Slingshot soon.<br />

LifeStraw ® - a world<br />

changing ideA<br />

Introduced nearly ten years ago<br />

by Switzerland-based Vestergaard, LifeStraw is a filtration<br />

device used to drink biologically contaminated water, yet<br />

avoid infection by parasites. One straw, can provide a<br />

person with 1,000 litres – all the drinking water they will<br />

need in a year.<br />

LifeStraw has played a critical role in many natural disasters,<br />

from the 2010 Haiti earthquake and Pakistan floods to the<br />

recent typhoon tragedy in the Philippines. LifeStraw works<br />

just like any other straw and can remove 99.9999% of waterborne<br />

bacteria and 99.9% of parasites.<br />

Simple solutions to tricky problems<br />

Sometimes the water issues facing the world’s poor are very<br />

immediate, small-scale, and concrete. Can I purify contaminated<br />

water? Can I get it home from a communal well or water hole?<br />

Can I pump it into a house, stable or field without the help of<br />

electricity?<br />

LifeStraw works just like any other straw and can remove 99.9999% of<br />

waterborne bacteria and 99.9% of parasites.<br />

Without rational answers to these questions, the result<br />

might be excessive expenditures of time and physical<br />

labour, illness, or both.<br />

Simple, practical solutions may bridge gaps that appear<br />

trivial to people in industrialized nations, but present genuine<br />

barriers to a third of humanity. Examples of such solutions<br />

are proliferating. They include the Filtrón clay filtration pot,<br />

from Potters for Peace of Latin America, and the Watercone ®<br />

solar water purifier, from Germany. Filtrón is a simple<br />

household filter which treats contaminated water in order to<br />

render it safe to drink. It consists of a simple clay filtering<br />

element that can be made by local potters using local materials,<br />

with no need for electricity or advanced technology. The filter<br />

has the capacity to meet the daily drinking water needs of a<br />

family of 6 to 8 people. The Watercone is a solar powered<br />

water desalinator that from salt water, generates up to 1,7 litres<br />

per day of freshwater - a child`s daily need of freshwater.<br />

Then there are the Q-Drum and the Hippo Water Roller,<br />

both South African, which greatly increase the amount of water<br />

that an adult or child can transport on foot. In both cases, the<br />

tethered water container rolls along the ground, a convenient<br />

feature if the well is several kilometres from one’s dwelling.

Hippo Water Roller which greatly increases the amount of water that an<br />

Q-Drum.<br />

For electricity-free pumping, San Francisco-based KickStart<br />

has come up with the Super-MoneyMaker: a foot-pedalled<br />

irrigation pump aimed at the African countryside where its<br />

efficiency can significantly increase a farm family’s ability to<br />

grow food, eat better, and so improve its finances.<br />

With equally serious intentions is the South African Roundabout<br />

PlayPump. This pump uses the energy of a spinning<br />

playground merry-go-round to pull water from a well up into<br />

a small water tower, and makes fetching water look like child’s<br />

play. While the concept’s practical value is still being proven, it<br />

exemplifies the spirit of creative yet pragmatic thinking in the<br />

search for solutions to the world’s many water challenges.<br />

Roundabout PlayPump.<br />

A shower that recycles its own waste-water<br />

Our personal hygiene habits emerged long ago as one of<br />

the culprits in heavy water use. A human only needs roughly<br />

a cubic meter of drinking water per year, yet per-person<br />

withdrawals of freshwater around the world range from a few<br />

hundred cubic meters to over two thousand cubic meters per<br />

year. A significant portion of this is due to baths and showers.<br />

Perhaps not surprising, then, that even in countries with<br />

relatively abundant water, rising awareness of energy and<br />

environmental issues has prompted a concerted effort to<br />

reduce bathroom water consumption, including low-flow<br />

shower-heads.<br />

For example, the new OrbSys Shower, which uses a technology<br />

originally developed for spaceflight, can purify and<br />

recycle 90% of the water that goes down its drain, returning<br />

it to the head for further use, reducing energy consumption<br />

by 80% compared to conventional shower. The beauty of<br />

this system is that, unlike low-flow heads, the OrbSys maintains<br />

a good strong flow rate, while still saving water, energy<br />

and money.

Water warriors;<br />

Harvesting rainwater to replenish<br />

underground water in India<br />

When rain falls, unless there is absorbent soil and various hollows and wetlands to trap it,<br />

the water will run off and vanish. This is a destructive process, leaving the land infertile and<br />

lowering groundwater to levels at which wells run dry. (Source: EcoTippingPoints.Org)<br />

Such was the situation encountered by Rajendra Singh, an<br />

idealistic young Indian doctor, and four of his friends, all part<br />

of the Tarun Bharat Sangh ("Young India Organization"),<br />

when they moved to the Alwar district of Rajasthan to start a<br />

clinic in 1985. Once there, they discovered that the greatest<br />

need was however water. There was a water crisis, and it was<br />

limiting the food farmers could grow and the incomes they<br />

could earn. Work began on restoring traditional earthen<br />

dams (johad) for rainwater catchment and underground<br />

water replenishment. Working only for food, a number of<br />

villagers joined the team to restore the first johad. The<br />

following year, a larger dam was restored with an estimated<br />

10,000 person-days of labour by the residents.<br />

Results from the very first pond were seen in just a<br />

few months.<br />

Gopalpura, holding over 735 million litres of water. The<br />

practice eventually spread to 750 other villages.<br />

Once the dams were constructed, they had only to wait for<br />

the monsoon rains. The ponds behind the dams filled with<br />

rainwater, which seeped into the underground water, and<br />

wells began to flow again. Underground transport of the<br />

water from dams to wells was achieved at no expense for<br />

infrastructure such as pipes or ditches, and no water was lost to<br />

evaporation. Rivers and streams were restored to year-round<br />

flows, providing further "free" water distribution. The higher<br />

water table meant that crops could grow with less irrigation<br />

and trees could grow close enough to villages to reduce the<br />

effort for firewood collection.<br />

Results from the very first pond were seen in just a few<br />

months. During the monsoon it filled with water and a nearby<br />

well began flowing again. This quick payback inspired more<br />

dam building. Ten years later there were 10 such ponds in<br />

The circle of positive effects—more water, more agriculture,<br />

more vegetation, less erosion, more water—and the related<br />

social benefits (e.g., men returning to the village) ensured<br />

the sustainability of the gains. It was no longer necessary for<br />

women and children to haul water from distant sources. As<br />

a consequence, women had more time for child care and<br />

supplemental economic activities, while children had time to<br />

return to school and the education that could provide them a<br />

more secure future.<br />

Now, almost thirty years later, Rajendra Singh is still labouring to<br />

restore the johad system. An entire society has been restored.<br />

Today, the impact of Singh and his “water warriors” can be felt<br />

across the entire region. Hundreds and hundreds of villages<br />

have resumed their traditional johad practices. The idea was<br />

simple. The water returned.

Water: The most critical asset<br />

in your production strategy<br />

It’s the new oil, and both need to be in the business mix.<br />

Source: extract from Huffington Post, by Michael Zacka, Cluster Vice President, Tetra Pak.<br />

No commodity seems to be more top-ofmind<br />

in the American consciousness than<br />

fuel. The media reports its price swings<br />

so frequently that I know the numbers<br />

by heart—today gas is $4.27 per gallon<br />

today in greater Chicago, where I work<br />

and reside, and crude oil just hit a ninemonth<br />

peak of $106.11.<br />

Justifiably, we angst continuously over the<br />

price of petroleum, yet we seem to have<br />

forgotten another precious, indispensable<br />

and dangerously depleting resource:<br />

water. And without this life-sustaining<br />

substance, nothing else matters.<br />

Like crude oil, water prices have surged in<br />

the last 12 years, doubling or tripling in<br />

many parts of the U.S, according to a USA<br />

Today study of 100 municipalities. Think<br />

of what that does to living expenses and<br />

business costs. And like crude oil, which<br />

is still threatened despite the current<br />

production boom here in the U.S., water<br />

is getting scarcer by the minute.<br />

Many Americans could soon realize this,<br />

since water shortages due to high demand<br />

and climate change have become<br />

a realistic possibility in New York City,<br />

Washington D.C., Los Angeles and San<br />

Diego—where approximately 40 million<br />

Americans reside—as well as most of<br />

Municipal water loss<br />

in Canada, Mexico<br />

California and breadbasket states including<br />

Nebraska, Illinois and Minnesota, notes<br />

Columbia University Water Center’s new<br />

study, “America’s Water Risk: Water<br />

Stress and Climate Variability.” The vast<br />

majority of our food is produced in these<br />

water-stressed regions.<br />

Analysts are constantly reminding us<br />

that new discoveries of ‘black gold’<br />

can’t keep up with declining production<br />

from established sources and rising car<br />

production, especially in Asia. Likewise,<br />

we need to raise awareness when it comes<br />

to water scarcity.<br />

Water Scarcity Is Everywhere<br />

that water demand will exceed supply<br />

by 40 per cent by 2030. Alan Hinchman,<br />

Global Market Director of Infrastructure<br />

at GE Intelligent Platforms, told my colleagues<br />

and me this disturbing statistic<br />

at a conference hosted by Tetra Pak for<br />

North American business leaders in the<br />

food and beverage industry. We called on<br />

GE since they’re now one of the world’s<br />

leading suppliers of sustainable water<br />

and process systems solutions.<br />

Alan also told us that municipal water<br />

loss in Canada, Mexico and the United<br />

States ranges between 20 and 50 per<br />

cent. Think about it: “for every 1,000<br />

gallons of water we use, somewhere<br />

between 250 to 1,000 more [gallons]<br />

were pumped and lost by leaking pipes,”<br />

Alan said. This helps explain why North<br />

Americans have the largest water footprint<br />

in the world (currently 2,060 gallons per<br />

person a day, according to nature.org). So<br />

not surprisingly, Alan warned us "North<br />

America has a huge water infrastructure<br />

bill coming due.”<br />

What The Numbers Mean<br />

Ironically, most companies have sophisticated<br />

and effective sustainability programs<br />

in place. Yet water management seems<br />

to be one of their least obvious areas of<br />

immediate concern, noted Alan, basing<br />

his analysis on astute observation: “I’m<br />

seeing more and more companies locating<br />

in water-challenged areas, even though<br />

the increased demand and reduced availability<br />

of quality water is raising its cost<br />

and the risk of productivity disruptions.”<br />

None of us can afford to waste water<br />

anymore. “Many civilizations have been<br />

crippled or destroyed by an inability to<br />

understand water or manage it. We have<br />

a huge advantage over the generations<br />

of people who have come before us,<br />

because we can understand water and<br />

we can use it smartly,” notes awardwinning<br />

journalist Charles Fishman in<br />

his ground-breaking tome, “The Big Thirst:<br />

The Secret Life and Turbulent Future of<br />

Water.” And everyone can achieve this<br />

goal. For example, between 1980 and<br />

now, farmers have reduced their water<br />

use by 15 per cent, but produce 70 per<br />

cent more food. That’s a 100 per cent<br />

increase in farm-water-productivity,<br />

notes Fishman.

CLEAR AND PRESENT DANGER<br />

People worldwide who either have no access to<br />

clean water or must walk to retrive it:<br />

How To Create A Water-Use Plan<br />

Bottom line, “we’re quickly going from a<br />

world where water is relatively free to one<br />

where it will cost a lot. The government<br />

will have to figure out the infrastructure<br />

issues, but we have to streamline our own<br />

processes and make smart water decisions<br />

right now,” Alan warned. Like innovation,<br />

which is an entire business practice area<br />

rather than just a single, or even series,<br />

of new solutions, it must become an integral<br />

and deep part of an overall business<br />

strategy. Experts like Alan say there’s room<br />

in every step of the production process for<br />

improvement.<br />

Here’s how:<br />

Determine the true cost of the<br />

1. water you use, starting with a<br />

comprehensive analysis of current water<br />

use, and allocate it more efficiently. A<br />

case in Australia illustrates this; water<br />

treatment giant Yarra Valley Water just<br />

had the British natural capital consultancy<br />

Trucost assess the real environmental costs<br />

of the water it uses, and found that one<br />

cubic meter of water actually ranges from<br />

ten cents to $15 AU in areas of extreme<br />

scarcity. Yarra Valley is now using this<br />

information to evaluate its new infrastructure<br />

investments, procurement<br />

strategies and product portfolios.<br />

Carefully manage your supply<br />

2. chain. Most companies’ direct<br />

water use pales in comparison to their<br />

embedded water use, which means the<br />

amount of water required to produce every<br />

aspect of a product from start to finish. For<br />

example, according to the U.S. Geological<br />

Survey, to make a single slice of bread,<br />

single cup of coffee or grow one pound<br />

of corn it takes 10, 35 and 110 gallons of<br />

water, respectively. According to the GE<br />

Water Facts video, it takes 2,700 gallons<br />

of water to make one hamburger. The<br />

supply chain is a primary focus of water<br />

stewardship activity for companies that<br />

include Ikea and Levi Strauss & Co. Levi has<br />

reduced water by 50 per cent since 2005<br />

through sustainable cotton cultivation.


TETRA PAK <strong>Magazine</strong><br />

Minimize water use in your<br />

3. production process. At Tetra<br />

Pak, our Design for Environment (DfE)<br />

program considers every aspect of product<br />

design, production and operation to reduce<br />

water loss, also offering this as a competitive<br />

advantage to our customers. For example,<br />

our Tetra Lactenso Aseptic with OneStep<br />

technology for the processing of aseptic<br />

milk reduces water utilization by 60 per<br />

cent and our Tetra Therm pasteurizers<br />

use cutting-edge intelligent automation<br />

to drive resource efficiencies that slash<br />

water consumption by up to 80 per cent<br />

compared to older versions.<br />

Increase water recycling and<br />

4. reuse. Manage water quality<br />

through responsible wastewater<br />

collection, treatment, recycling and disposal,<br />

and monitor activities that can<br />

potentially cause water quality problems.<br />

Reusing wastewater can reduce<br />

the potential impact of discharging<br />

pollutants into water sources, and/or<br />

reduce the demand on potable water<br />

supplies.<br />

Design Water-Savvy Plants and<br />

5. Products. Sustainable design<br />

must go from ‘emergent’ to ‘entrenched’<br />

right now. Any product design process<br />

must start with a total life cycle analysis<br />

that gauges its water impact. This<br />

means taking into consideration the<br />

entire supply chain, manufacturing and<br />

distribution procesand how it will be<br />

recycled and/or disposed of to optimize<br />

its water metrics.<br />

All of these processes can help us better<br />

manage this precious resource, but are<br />

just a starting point. So here is to hoping<br />

it won’t be long before we all figure out<br />

how to not only implement them, but also<br />

come up with innovative new strategies<br />

to better these methods.<br />

A global thirst for<br />

designer water<br />

As sales of carbonated soft drinks continue to decline in advanced markets,<br />

global demand for packaged water is booming. What is behind today’s<br />

enthusiasm for bottled H₂O in all its innovative forms?<br />

©Tetra Pak


TETRA PAK <strong>Magazine</strong><br />

25<br />

Packaged water has now surpassed<br />

carbonated drinks as the leading<br />

non-alcoholic beverage category.<br />

Consumers are lapping up the<br />

growing number of packaged water<br />

options available on the market, with<br />

Europe and North America accounting<br />

for about 50% of global sales. In many<br />

developed countries, the success of<br />

packaged water rests on the lifestyle<br />

trends of more health-conscious<br />

consumers. However, in some of the<br />

emerging markets, demand is also<br />

driven by a need for safe drinking water<br />

in areas where municipal supplies are<br />

not always reliable. In the context of<br />

emergency relief efforts, the distribution<br />

of hundreds of thousands of<br />

packages of pure drinking water to<br />

the victims of a natural disaster is a<br />

familiar image. Sometimes a sealed<br />

package of pure water is literally a<br />

life-saver.<br />

Sparkling, mineral, or with<br />

a hint of citrus?<br />

Packaged water is a hugely successful<br />

product, even where municipal<br />

water supplies are safe and trustworthy.<br />

In France and Italy, packaged<br />

mineral water has long been popular<br />

in both restaurants and homes, with<br />

well-known brands associated with<br />

particular natural sources. People often<br />

have a favourite, and will describe the<br />

virtues of their preferred brand with<br />

the lyrical enthusiasm usually reserved<br />

for wine. A favourite mineral water is<br />

not only superior in taste, according to<br />

its fans, but it’s also full of great health<br />

benefits.<br />

No one can argue that drinking plenty<br />

of pure water isn’t good for you –<br />

indeed, the spread of packaged water<br />

in the developed world has proceeded<br />

alongside the health and fitness trends<br />

of recent decades. As with other<br />

products, a previously generic basic<br />

commodity - drinking water - has been<br />

transformed into an expression of<br />

individual taste.<br />

For consumers who love water but<br />

enjoy added taste, producers have<br />

come up with a multitude of innovative<br />

flavoured water options. One British<br />

supermarket giant for example, lists no<br />

less than 145 different water choices on<br />

its website, of which 45 are flavoured.<br />

In some ways, these offer health-conscious<br />

people the best of both worlds:<br />

a diversity of tastes without any of the<br />

calories!<br />

Water in a Box<br />

Packaged water is also popular in<br />

single portions to be consumed on the<br />

go – practical for picnics, sports and<br />

lunch boxes. Many schools prohibit<br />

the consumption of sugary drinks on<br />

their premises but have no objection<br />

to water, whether sparkling, still or<br />

flavoured.<br />

Packaging in all shapes and<br />

sizes<br />

With all these thirst-quenching options<br />

on the market, producers of ‘designer’<br />

water work hard to differentiate their<br />

product through innovative and<br />

eye-catching packaging. A popular<br />

alternative is water in carton packages,<br />

which are robust, stackable and have<br />

a smaller carbon footprint than their<br />

plastic counterparts. Cartons also allow<br />

for colourful, eye-catching designs<br />

while satisfying many consumers’<br />

requirements for an environmentally<br />

friendly product.<br />

UK based Vivid Waters has recently launched Water in a Box, a plain plus three<br />

flavoured water range packed in Tetra Pak ® cartons. Aimed at on the go consumption,<br />

the drinks are packed in Tetra Prisma ® Aseptic 330 Sq cartons with DreamCap,<br />

an innovative drink-from, re-closable cap.

Purity and convenience<br />

Some packaged water originates from<br />

a particular natural spring and takes its<br />

name from that spring. These products<br />

are associated with a location in<br />

the same way as a cheese or wine; their<br />

brand is the name of the location. Water<br />

from some of these famous sources<br />

is claimed to have health-enhancing<br />

properties and many of these brands<br />

have a distinctive taste. Some are also<br />

naturally carbonated, or contain certain<br />

minerals, features that producers<br />

emphasise in their marketing.<br />

Other water brands are in fact simply<br />

tap water from a municipal source which<br />

has been purified through a process of<br />

reverse osmosis, ozonation, distillation<br />

or deionization. The benefit for the<br />

consumer is mainly in the convenience<br />

of the packaging and the guarantee of<br />

a pure, safe product. Where municipal<br />

water is unsafe to drink, packaged water<br />

is more than just trendy and convenient;<br />

it is a necessity.<br />

People can boil tap water in their<br />

homes, but when they are out and<br />

about, a sealed package is their safest<br />

option. This accounts for the increase<br />

in sales of packaged water in parts<br />

of the world such as India, where<br />

consumption is expected to increase<br />

annually by more than 20% in the<br />

next few years. Asian markets already<br />

account for around a third of global<br />

sales of packaged water, with plenty of<br />

room for expansion.<br />

Meanwhile, producers are coming up<br />

with ever more innovative and enticing<br />

versions of good old plain drinking<br />

water.<br />

Coconut water<br />

Coconut water has moved from being a niche health<br />

product to an increasingly popular drink around the world particularly<br />

over the last five years.<br />

Changing consumer tastes and increasing health awareness have been important<br />

factors in bringing about the success of coconut water. Coconut water is<br />

naturally low in fat, and has a number of health benefits: it contains electrolytes<br />

(potassium, magnesium, sodium, calcium, and phosphorous) needed for natural<br />

rehydration and provides similar benefits to energy and sports drinks.<br />

As coconut water has become more and more popular, the demand for<br />

products that people can drink on-the-go has increased and the majority of<br />

coconut water is in fact sold in individual, on-the-go portion packs.<br />

Tetra Pak was the first company to introduce aseptically packed coconut<br />

water which could be stored for long periods and packaged without altering<br />

its natural texture and nutrients. Today, the company works closely with<br />

coconut water customers around the world to provide packaging solutions<br />

which ensure product safety and convenience for consumers.<br />

In 2012 Tetra Pak opened a Coconut Knowledge Centre in Singapore. This<br />

centre enables us to understand the characteristics of coconut products;<br />

provide technical support to customers; develop new recipes; and expand<br />

knowledge sharing among our international network of experts.<br />

Cactus Water<br />

True Nopal Cactus Water was recently launched in America, packed in<br />

Tetra Prisma ® Aseptic 1000 ml Square packages, maintaining its freshness.<br />

True Nopal is made with the nutritious fruit of the prickly pear cactus<br />

and is 100 per cent all natural with no added sugars, no fat, no cholesterol,<br />

no GMOs and is gluten-free.<br />

A maybe less known but very healthy option is cactus water. Already a<br />

popular beverage in Mexico, South America, India, the Middle East and parts<br />

of Europe, it has recently caught on in popularity in the United States too.<br />

Cactus water comes from prickly pears - the fruit produced by one particular<br />

cacti, Opuntia - which offer a range of health benefits, containing a variety of<br />

vitamins, a high fibre content and are rich in magnesium and potassium.<br />

Additionally, this fruit is rich in amino acids, specifically taurine. Taurine has<br />

antioxidants and flavonoids, both of which are beneficial to the body.<br />

Faroe Water<br />

Faroe Water orginates from the remote North Atlantic location of<br />

the Faroe Islands. Deep within the mountains are natural springs<br />

where crystal clean Atlantic rain seeps into mountain crevices and<br />

settles into pristine wells.<br />

Aqua Zana<br />

Aqua Zana, natural spring water from the Canary Islands,<br />

recently released by JSP and packed in Tetra Prisma ® Aseptic<br />

Exploration<br />

and trade<br />

©Lucky Look/Alamy<br />

Over millennia water has exerted an extraordinary pull on the human imagination.<br />

It seems that we only have to see a sea to want to travel across it. The following<br />

conquests enabled the world to become connected and, through trade, stay connected.


TETRA PAK <strong>Magazine</strong><br />

29<br />

But the true ‘Age of Sail’ was launched by Vasco de<br />

Gama when he sailed round the Cape of Good Hope<br />

and reached Calicut. Thanks to Vasco’s seafaring<br />

skills, control of the spice trade started to move<br />

from the East to the West. Trade in the East Indies<br />

was dominated by Portugal in the 16th Century, the<br />

Dutch Republic in the 17th century and the British in<br />

the 18th Century.<br />

Connecting continents<br />

A history of the great sea-faring nations doubles up<br />

as a history of how nations learned to speak to one<br />

another, although not always peacefully. There are<br />

the Polynesians who used balsa-log boats to colonise<br />

the Pacific; or the Vikings who used their long ships<br />

to travel as far east as Constantinople and as far west<br />

as Newfoundland; or the British who colonised North<br />

America and Oceania and discovered the South Pole;<br />

or the Spanish who colonised America and were the<br />

first to circumnavigate the globe; or the Portuguese<br />

who discovered a way round Africa to India and were<br />

the first Europeans to travel to Indonesia, China and<br />

Japan.<br />

Trading on rivers and canals<br />

De Gama’s feat has been regarded by many as the<br />

‘Big Bang’ of globalization. However, water voyages<br />

have not all been on a grand or international scale.<br />

Travel and trade has always been a feature of life<br />

up and down rivers, and where no natural waterways<br />

existed, people have often created them. The<br />

building of canals was started by the Mesopotamians<br />

as early as 4000 BC, and continued by the Chinese<br />

when they created the Grand Canal of China, still<br />

the longest canal in the world, at the turn of the 7th<br />

Century. Canals provided the infrastructure for the<br />

Industrial Revolutions in both America and Britain.<br />

Over time, they were superseded by rail and road.<br />

But even to this day, the Panama and Suez Canal are<br />

of vital strategic importance.<br />

All these amazing feats of seamanship created the first<br />

trade bonds. Both the Silk Road and the maritime Silk<br />

Route were established in the 1st Century BC thereby<br />

providing the opportunity for East to meet West.<br />

And for an extraordinary four centuries (beginning<br />

in the13th century) the Hanseatic League allowed a<br />

collection of naval cities to form a trade monopoly<br />

over most of Northern Europe and the Baltic, making<br />

their merchants the wealthiest in Europe.<br />

How water turned hunter-gatherers<br />

into farmers and engineers<br />

It is not an exaggeration to say that the birth of major human civilization depended on<br />

close proximity to water. Enormous leaps forward, such as the invention of writing and<br />

irrigation technology, first happened in early human settlements located along major<br />

rivers in very different parts of the world.<br />

Reaping what you sow<br />

Until approximately 10,000 years ago, our ancestors did<br />

not deliberately sow and harvest plants for consumption.<br />

Communities subsisted on hunting and gathering, for which<br />

they had developed tools and techniques. But certain<br />

groups, in locations with a steady and relatively predictable<br />

supply of fresh water, were able to take a great developmental<br />

step forward in the form of early agriculture. This occurred<br />

independently in several very different parts of the world;<br />

each time in proximity to one or several rivers.<br />

Sowing and harvesting crops meant that these early communities<br />

no longer had to be nomadic in order to survive<br />

by hunting for edible plants and following game. Instead<br />

they could focus on developing technologies to improve<br />

their harvest: early engineering projects were in fact often<br />

destined to control the flow and availability of water for<br />

crops.<br />

Early urban planning along the Indus<br />

This pattern – freshwater supply, agriculture, irrigation<br />

systems - appears in the four major early riverine civilizations<br />

which gave rise to the first sophisticated city states. It seems<br />

that mastering the water supply was key to the development<br />

of many other technologies, allowing human communities<br />

to take their skills and knowledge to a completely new level.<br />

Consider Harappa, an ancient city-state in the Indus Valley.<br />

As early as 3000 BCE, this impressive civilization had sewerage<br />

and drainage systems that were far more advanced<br />

than many to be found elsewhere in later centuries. Good<br />

The Indus Valley Civilization Pakistan 1865.<br />

hygiene, coupled with efficient irrigation systems, allowed<br />

the population along the Indus to flourish. Controlling the<br />

freshwater supply and the flow of waste water was crucial to<br />

the success of the Harappan civilization, which numbered<br />

over five million people at its height. Harappan cities were<br />

constructed using advanced urban planning and building<br />

techniques. They applied a uniform system of weights and<br />

measures and are credited with inventing dentistry as well as<br />

a system of writing known as Indus script.<br />

Irrigation canals in the cradle of civilization<br />

Similarly, the first city-based civilization in Mesopotamia,<br />

around 3300 BCE, developed irrigation systems to divert<br />

water from the two great rivers to crops in the region in<br />

between them. Communities living in what is known as the<br />

cradle of civilization learned to exploit the water supply<br />

through a system of man-made canals, thereby guaranteeing<br />

Chinese civilization.<br />

more reliable food production. Maintenance of the irrigation<br />

network required a large amount of human labour, which led<br />

to the development of urban centres and, eventually, citystates.<br />

The fertile plains of Mesopotamia sustained the fertile<br />

minds of their inhabitants, who went on to develop a written<br />

language (Sumerian), in addition to mathematics, astronomy,<br />

medicine, literature, philosophy and art.<br />

Exploiting floodwater along the Nile<br />

In ancient Egypt as well as along the Indus and in Mesopotamia,<br />

irrigation technology also included the diversion of flood water.<br />

The rich sediments in the flood waters improved agricultural output,<br />

and the more secure food supply in turn allowed people to<br />

focus on innovations beyond irrigation systems. Fishing will have<br />

provided much-needed protein as well, probably contributing<br />

to the population’s chances of thriving and developing new skills<br />

and abilities. Visitors to Egypt today still marvel at the innovative<br />

capabilities of the ancient Egyptians and their unrivalled building<br />

techniques, of which the famous pyramids, temples and monumental<br />

statues provide abundant proof.<br />

human endeavour besides agriculture. Architecture, urban<br />

planning, art and handicrafts all developed in the early city<br />

states, along with the great human breakthrough of written<br />

language. In addition to providing essential water, the rivers<br />

also acted as communication channels between the various<br />

settlements along their banks. Traders and artisans exchanged<br />

knowledge and skills, while materials were brought from distant<br />

regions to produce artefacts, some of which are still being<br />

unearthed by archaeologists today.<br />

Without access to fresh water in the form of major rivers,<br />

human civilization might never have developed as it did. The<br />

many inventions and discoveries originating in the ancient<br />

riverine civilization indicate that human potential is generally<br />

enhanced and supported by the addition of water. This is<br />

even true today, as access to clean drinking water, irrigation<br />

for crops and good waste water disposal are preconditions<br />

for the successful development of communities all over the<br />

planet.<br />

Water fosters human ingenuity<br />

Chinese civilization was also born along a river – or more<br />

than one. The Yellow River, or Huang He, was apparently<br />

harnessed for irrigation purposes as early as the third<br />

millennium BCE. The importance of irrigation engineering for<br />

the region was such that warring city states would sabotage<br />

each other’s canals and dykes, deliberately causing floods<br />

in rival territories. But in peacetime, along these ancient<br />

rivers, human ingenuity exploded in the form of technological<br />

advances, with a spill-over effect into many areas of<br />

see further and stay longer beneath the water than other<br />

humans. When the tsunami ravaged the coast of Thailand in<br />

would allow some 30,000 people to relocate to a series of<br />

artificial islands that float on the water like lily pads. Islands<br />

can be linked together to form self-sustaining “cities” that<br />

include residential units, offices, services, shops, and even<br />

arable land for growing crops.<br />

While the floating islands of Africa and Kiribati have yet to become<br />

reality, an enterprising artist/ecologist has already created an artificial<br />

floating island on a much smaller scale. Rishi Sowa built Spiral Island II,<br />

which floats near Cancun, Mexico, out of 100,000 recycled plastic bottles.<br />

The sandy island is about 18 metres in diameter, and includes a house,<br />

mangrove trees, and even a duck pond.<br />

Nigerian architect Kunlé Adeyemi is working on plans for<br />

water cities that will allow the coastal waters of Africa to<br />

sustain floating dwellings that minimize ecological impact,<br />

expand the habitable area, and enable residents to weather<br />

adverse environmental conditions including flooding and<br />

storms. His living structures float on recycled barrels and are<br />

powered sustainably by solar panels.<br />

Whilst working on plans for a floating village, Nigerian architect Kunlé<br />

Adeyemi has designed and built, using local materials and labour, a<br />

floating school in the watery heart of Makoko. Floating on 256 plastic<br />

barrels the school offers classrooms for around 100 children.

Taking the plunge<br />

Some people simply love the freedom of life on the water.<br />

They trade a mortgage for moorage without a backward<br />

glance at their old, landlocked lifestyle.<br />

Water shifts and flows in ways that make life interesting,<br />

especially when you can pick up any time and follow its<br />

unpredictable course. All over the world, adventurous,<br />

independent spirits choose to live on sailboats, longboats,<br />

and houseboats that allow them to blend the comforts of<br />

home with the thrill of adventure.<br />

Amsterdam’s houseboat culture is a unique part of the city’s<br />

distinctive charm. Today, about 2,500 houseboats—some of<br />

them more than 100 years old—float along its labyrinthine<br />

canal system, offering a unique mode of living for artists,<br />

professionals and families.<br />

Britain’s 2,000 miles of navigable waterways are also home<br />

to more than 15,000 people who live on houseboats and the<br />

distinctive, colourful narrow-boats designed to navigate the<br />

nation’s slender canals.

Liquid Love<br />

For creatures with no gills or fins, we humans seem to have a surprisingly intense<br />

relationship with water. What is behind the love affair between us and H 2<br />

O?<br />

We need water to survive, of course; along with oxygen it is<br />

a non-negotiable factor for sustaining life. A strong human<br />

being can survive for a month without food, but not more<br />

than about 3 days without water.<br />

Fontana di Trevi, Italy<br />

So it makes sense that human beings<br />

have evolved to value the presence<br />

of water and particularly of clean, drinkable,<br />

running water. Yet our fascination<br />

with the stuff that covers about 70% of<br />

our blue planet and makes up almost<br />

two thirds of our bodies goes well<br />

beyond mere utility. Throughout history,<br />

our civilizations have developed and<br />

thrived at the water’s edge. In addition,<br />

we connect to water as individuals: we<br />

bathe in it, drink it, play and relax in it,<br />

use it to heal and soothe our bodies<br />

and minds. In communities all over the<br />

planet, human beings have integrated<br />

water into their architecture, religious<br />

rituals, leisure activities, health and<br />

wellbeing.<br />

Were our ancestors aquatic<br />

mammals?<br />

One tentative explanation for this<br />

intense relationship with water is the<br />

Aquatic Ape Hypothesis, according to<br />

which we all descend from a common<br />

aquatic ancestor. This theory has not<br />

gained mainstream support within the<br />

scientific community, although it has<br />

some eminent proponents, including<br />

Sir David Attenborough (the English<br />

naturalist and former BBC 2 senior<br />

manager, broadcaster of natural history<br />

programmes for more than 60 years).<br />

Some of the arguments in its favour<br />

are compelling - especially when you<br />

compare the human body to that of<br />

other land mammals, most of which are<br />

covered in hair. We, in contrast, appear<br />

to have more in common with dolphins<br />

and seals than with sheep or bears: our<br />

smooth bodies, upright stance and<br />

subcutaneous fat make us better<br />

adapted to an aquatic environment.<br />

©Metvert/Scoreit.se<br />

And if our hominid ancestors lived in<br />

or by bodies of water, it can be argued<br />

that the fish and seafood they ate - rich<br />

in Omega 3 fatty acids - resulted in<br />

their brains evolving to become the<br />

largest among the genus Homo. If<br />

that is correct, we would owe our very<br />

intelligence to our ancient relationship<br />

with water. While these theories remain<br />

to be scientifically proven, the love<br />

affair between humans and water is<br />

still going strong - starting, arguably,<br />

before we are even born.<br />

Swimming underwater is<br />

child’s play<br />

Ultra-sound images reveal human<br />

babies floating happily in amniotic<br />

fluid until the moment of birth. Newborns<br />

retain an uncanny ability to swim<br />

underwater and an efficient reflex that<br />

prevents them from breathing water<br />

into their lungs. Not only can they<br />

cope with an aquatic environment,<br />

they appear to find it very agreeable.<br />

For most children, the loss of the<br />

neonatal ability to swim is followed by<br />

years of delighted play in and around<br />

water.<br />

Soothing the body and the<br />

human spirit<br />

We still use water in therapeutic<br />

contexts, as humans have done since<br />

ancient times. Throughout history,<br />

people have found different ways of<br />

harnessing the soothing properties<br />

of water to enhance their health and<br />

well-being. The ancient Romans elevated<br />

their thermal bath rituals into an art, as<br />

they took to the water – cold, warm or<br />

in steam form - in magnificent surroundings.<br />

Not all spa enthusiasts<br />

of today know that they are merely<br />

continuing in the same tradition, as<br />

the word spa is nothing more than<br />

an acronym for the Latin expression,<br />

Salute per Aqua, or Health through<br />

Water.

Water-powered deities<br />

Polytheistic religions frequently feature<br />

a river or sea deity with great power,<br />

such as the Greek Poseidon or Roman<br />

Neptune. In Chinese mythology, Gong<br />

Gong was a powerful water god, whilst<br />

He Bo was the god of the Yellow River,<br />

or Huang He.<br />

A common thread among these diverse<br />

watery deities is their association with<br />

both destructive and life-giving powers.<br />

In many sea-faring cultures, a sea god<br />

has to be appeased in order to protect<br />

sailors and fishermen. The sea is<br />

their livelihood, but also a dangerous<br />

environment for humans, and this is<br />

often reflected in its symbolic personification.<br />

Among the more appealing features<br />

of aquatic deities are beauty, fertility<br />

and purity. The Greek goddess<br />

Aphrodite, for example, emerged from<br />

the sea while the Zoroastrian divinity,<br />

Tishtrya, brings life-giving rain and<br />

hence fertility to both the land and its<br />

human inhabitants.<br />

Without water there is no life!<br />

And second, water is a primary building<br />

block of life. Without water there is no<br />

life, yet water has the power to destroy<br />

as well as to create.<br />

The significance of water varies in<br />

different religions and beliefs but<br />

these two qualities of water lie behind<br />

its place in most cultures and faiths.<br />

African water deities are often female<br />

(the Yoruba goddess Oshun, for<br />

example, or her Igbo river counterpart<br />

Idemili) and associated with beauty,<br />

fertility and motherhood. The lifefostering<br />

properties of water seem to<br />

be embodied in these divine entities.<br />

signs of previous defilement. Water<br />

not only purifies objects for ritual use,<br />

but it cleanses a person, externally or<br />

spiritually, ready to come into the<br />

presence of his/her focus of worship.<br />

A treasure worth protecting<br />

Evidently our passion for water runs<br />

deep – as it were – only adding to the<br />

many reasons we already have to value<br />

this essential resource. Whether or not<br />

we descend from an ancient aquatic<br />

ancestor, as a species we have benefited<br />

from proximity to water. It remains a<br />

vital necessity, as well as a source of<br />

pleasure and well-being.<br />

Cleansing & Purifying<br />

Human societies as far apart as the<br />

river Jordan and the Ganges have<br />

placed their hopes in the river’s capacity<br />

to cleanse and purify, allowing the<br />

believer to emerge renewed - reborn,<br />

in a sense - as a result.<br />

Water has a central place in the<br />

practices and beliefs of many religions<br />

for two main reasons. First, water<br />

cleanses. Water washes away impurities<br />

and pollutants, it can make an object<br />

look as good as new and wipe away any<br />
