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.

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 />
%<br />
Americans reside—as well as most of<br />
Municipal water loss<br />
in Canada, Mexico<br />
and the United States<br />
ranges between 20<br />
and 50 per cent.<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 />
Unpardonably, 2.6 billion people—more<br />
than a third of the world’s population<br />
—don’t have access to clean water or live<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 />
4<br />
– out of –<br />
10<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 />

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 />

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 />

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 />

There’s no place<br />

While most of us cling to the comforting stability of terra firma,<br />
others find creative ways to make the world’s oceans, lakes, and<br />
waterways their permanent home.<br />
Water may be essential to life, but the<br />
land is where humans usually choose to<br />
live. We may venture out on the water<br />
for recreation, adventure or solitude,<br />
but few of us can bear to be cut adrift<br />

would it be like to live each day without<br />
ever setting foot on dry land? For most<br />
of us, it’s hard to imagine. For some, it’s<br />
a simple fact of life.<br />
While exact numbers are hard to come<br />
by, more people are living on the water<br />
than you might think. Through choice or<br />
necessity, individuals—and sometimes<br />
even entire communities—are leaving<br />

drift for most of the year. Over time, the water has actually<br />
changed their physiology: the Moken have the ability to<br />
see further and stay longer beneath the water than other<br />
humans. When the tsunami ravaged the coast of Thailand in<br />

re-house the “climate refugees” who will soon be pushed<br />
out of their homes by rising sea levels. This development<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 />
