Do you use the same tech<strong>no</strong>logy <strong>to</strong><br />

produce bi<strong>of</strong>uels from all these<br />

products?<br />

It’s the same general principles. But<br />

some types <strong>of</strong> oil require more processing,<br />

more refining and more energy,<br />

which makes them more or less<br />

cost-effective and more or less practical<br />

as bi<strong>of</strong>uels.<br />

What’s the most efficient product?<br />

There are various new products being<br />

used. Algae is very <strong>go</strong>od for making<br />

biodiesel. It is also <strong>go</strong>od for the environment<br />

because for the same land<br />

space needed for soya you could produce<br />

a thousand times more oil. There<br />

are also crops like jatropha (an evergreen<br />

shrub with oily seeds) that grows<br />

in the desert where you couldn’t grow<br />

INTERVIEW<br />

Andy Pag Self-styled green traveler talks about his round-the-world trips on low-carbon fuels<br />

On the road, with a tankful <strong>of</strong> waste<br />

Grease <strong>to</strong> Greece<br />

‘The idea behind the Greek<br />

traveled and the way <strong>to</strong> do<br />

this was <strong>to</strong> k<strong>no</strong>ck on the<br />

doors <strong>of</strong> restaurants asking<br />

for their waste oil’<br />

‘I just wanted <strong>to</strong> <strong>go</strong> on<br />

holiday without feeling<br />

guilty. My wife and I<br />

drove from London <strong>to</strong><br />

Cape Town and it<br />

dawned on us that we<br />

were contributing a<br />

mass <strong>of</strong> CO2 emissions<br />

in the process’<br />

BY NIKI KITSANTONIS<br />

Sometimes one person with a <strong>go</strong>od idea<br />

and a lot <strong>of</strong> determination can capture<br />

the attention <strong>of</strong> the public and communicate<br />

a concept more eloquently<br />

than a host <strong>of</strong> international organizations<br />

and pressure groups. Andy Pag<br />

is one <strong>of</strong> these people. A 34-year-old engineer<br />

and webcasting specialist from<br />

South London, he has organized a series<br />

<strong>of</strong> unprecedented road trips <strong>to</strong><br />

demonstrate the potential <strong>of</strong> alternative<br />

energy as petrol prices rise, fossil<br />

fuel reserves dwindle and the world<br />

heats up from the carbon dioxide (CO2)<br />

emissions these fuels release.<br />

Last year Pag traveled from London<br />

<strong>to</strong> Timbuktu in a truck running on fac<strong>to</strong>ry-reject<br />

chocolate. Last month, he<br />

and fellow travelers drove from London<br />

<strong>to</strong> <strong>Athens</strong> in a car running on used vegetable<br />

oil, s<strong>to</strong>pping <strong>to</strong> fill up at restaurants<br />

rather than gas stations. Now<br />

planning a trip <strong>to</strong> China – which will<br />

involve brief flights with a small aircraft<br />

fed by household trash – Pag spoke <strong>to</strong><br />

<strong>Athens</strong> Plus about his experiences as<br />

a self-proclaimed “petrol-head” and<br />

promoter <strong>of</strong> “<strong>go</strong>od” bi<strong>of</strong>uels.<br />

What was the philosophy behind<br />

your most recent expedition <strong>to</strong><br />

Greece, on grease?<br />

The idea behind the Greece trip was<br />

<strong>to</strong> see if we could find sustainable fuels<br />

as we traveled and the way <strong>to</strong> do this<br />

was <strong>to</strong> k<strong>no</strong>ck on the doors <strong>of</strong> restaurants<br />

asking for their waste oil. It<br />

started <strong>of</strong>f as an idea for a holiday for<br />

me and my wife but then more and<br />

more people wanted <strong>to</strong> get involved and<br />

Bi<strong>of</strong>uel production tech<strong>no</strong>logies ‘as simple as using a washing machine’<br />

food anyway. Everything we have<br />

used has been waste.<br />

How viable are these tech<strong>no</strong>logies for<br />

use by the public?<br />

It is pretty straightforward. Most participants<br />

in the Greece rally were<br />

<strong>no</strong>vices. The fuel pod we <strong>to</strong>ok with us<br />

is the sort <strong>of</strong> thing you fill up with used<br />

vegetable oil once a week, leave the machine<br />

running for four or five hours and<br />

it produces biodiesel for you. It’s about<br />

as complicated as using a washing machine.<br />

How did you become an<br />

environmentalist/bi<strong>of</strong>uel guru?<br />

I just wanted <strong>to</strong> <strong>go</strong> on holiday without<br />

feeling guilty. My wife and I drove<br />

from London <strong>to</strong> Cape Town three years<br />

it ended up a rally with 10 teams.<br />

What sort <strong>of</strong> response did you get<br />

from the restaurant owners? Were<br />

they happy <strong>to</strong> help or bemused?<br />

Pretty positive. The only times they<br />

didn’t give us their used oil was when<br />

it had already been collected. Some<br />

were curious at first but then were keen<br />

<strong>to</strong> convert their own vehicles. The<br />

best oil was in Germany – they are very<br />

<strong>go</strong>od at changing their fryers so the oil<br />

was quite clean. The worst oil was what<br />

we set <strong>of</strong>f with from the UK.<br />

What about Greek oil?<br />

Actually we <strong>to</strong>ok a load <strong>of</strong> Greek oil<br />

when we left for the re<strong>turn</strong> journey but<br />

it had been used <strong>to</strong> fry fish and, as a result,<br />

it was quite watery, which makes<br />

it quite hard <strong>to</strong> filter, but it was very<br />

a<strong>go</strong> and it dawned on us that we were<br />

contributing a huge amount <strong>of</strong> carbon<br />

dioxide (CO2) emissions in the process.<br />

This led <strong>to</strong> the chocolate-fueled trip <strong>to</strong><br />

Timbuktu. The more research I did in<strong>to</strong><br />

bi<strong>of</strong>uels, the more I wondered why<br />

more people aren’t using them. The bi<strong>of</strong>uels<br />

industry hasn’t promoted itself<br />

very well – there’s been more infighting<br />

than presenting a clear message.<br />

So have you given up your full-time<br />

job <strong>to</strong> be a bi<strong>of</strong>uel promoter?<br />

No, I just do this for holidays. I run<br />

a company webcasting weddings. I’ve<br />

always put aside one month <strong>of</strong> the year<br />

<strong>to</strong> organize expeditions.<br />

And the next s<strong>to</strong>p is China next<br />

year, I hear. Is it true that you are<br />

clean and <strong>go</strong>od quality oil – and olive<br />

oil, <strong>to</strong>o, which was a first.<br />

So you’ve used chocolate and<br />

vegetable oil. What other products<br />

can be used <strong>to</strong> produce bi<strong>of</strong>uels?<br />

Basically anything that has oil in it<br />

because oil contains energy. In the<br />

Greece rally I was driving a car with a<br />

converted engine that would take<br />

used vegetable oil directly. Other vehicles<br />

in the rally used a fuel “pod” that<br />

we carried with us and that converted<br />

the vegetable oil <strong>to</strong> biodiesel that<br />

could then be used in the car engines.<br />

A<strong>no</strong>ther alternative fuel is bioetha<strong>no</strong>l,<br />

a petrol substitute that can be made<br />

from anything that has sugar in it. But<br />

bioetha<strong>no</strong>l is much more flammable<br />

and so can be dangerous – <strong>no</strong>t really a<br />

viable home brew alternative.<br />

TARGETS & LIMITS CROP FUNCTIONS<br />

The European Union dictates<br />

that fuel companies’ production<br />

must include 10 percent <strong>of</strong><br />

bi<strong>of</strong>uels by 2010. But firms are<br />

looking at the cheapest option,<br />

which invariably is <strong>to</strong> get their oil<br />

by chopping down rain forests.<br />

Hopefully this will change over<br />

the next year when the EU<br />

directive is refined <strong>to</strong> balance<br />

sustainability against<br />

production.<br />

There probably isn’t e<strong>no</strong>ugh<br />

waste material out there <strong>to</strong> feed<br />

our <strong>to</strong>tal fuel needs but at the<br />

same time there is an awful lot <strong>of</strong><br />

waste <strong>go</strong>ing <strong>to</strong> waste. Every drop<br />

<strong>of</strong> used vegetable oil that we use<br />

in our cars is one less drop <strong>of</strong><br />

crude oil used. It would be nice<br />

<strong>to</strong> get <strong>to</strong> a saturation point<br />

where all the waste is being<br />

used. It might <strong>no</strong>t be e<strong>no</strong>ugh <strong>to</strong><br />

free us from our dependency on<br />

fossil fuels but it would certainly<br />

make a positive impact.<br />

There has been a lot <strong>of</strong><br />

controversy about the<br />

“downside” <strong>of</strong> bi<strong>of</strong>uels, chiefly<br />

about the ethics <strong>of</strong> food being<br />

used for fuel.<br />

I am <strong>no</strong>t an environmentalist – if<br />

anything I’m a petrol-head – but<br />

I’ve researched the subject. There<br />

is the argument that the use <strong>of</strong><br />

crops in Europe for bi<strong>of</strong>uels has<br />

been responsible for rising food<br />

prices. The other argument is that<br />

the cost <strong>of</strong> food is quite energydependent<br />

– you need<br />

agricultural machinery,<br />

transportation, packaging – and<br />

all that is being driven by the high<br />

cost <strong>of</strong> crude. It’s ironic – growing<br />

more bi<strong>of</strong>uels might drop the<br />

price <strong>of</strong> fossil fuels! Also there’s a<br />

lot <strong>of</strong> confusion about <strong>go</strong>od<br />

bi<strong>of</strong>uels versus bad bi<strong>of</strong>uels.<br />

There are some bi<strong>of</strong>uels being<br />

made that are damaging the<br />

environment but there are also<br />

lots <strong>of</strong> bi<strong>of</strong>uels that are <strong>go</strong>od.<br />

<strong>go</strong>ing <strong>to</strong> fly part <strong>of</strong> the way there on<br />

waste products?<br />

We’ll drive but also take a small aircraft<br />

called a paramo<strong>to</strong>r, basically a<br />

parachute with an engine. I’m <strong>go</strong>ing <strong>to</strong><br />

film villages from the air and give the<br />

videos <strong>to</strong> the residents so they can see<br />

what their villages look from the air. I’ve<br />

started paragliding lessons already.<br />

What’s this trip <strong>go</strong>ing <strong>to</strong> be fueled by?<br />

A range <strong>of</strong> alternative fuels, all sustainable.<br />

We’ll be using waste oil <strong>to</strong> run<br />

the truck. Then we’re using a process<br />

called Fischer-Tropsch Synthesis, a<br />

process that takes household rubbish<br />

and plastic bags and <strong>turn</strong>s them in<strong>to</strong><br />

aviation fuel. We’re working with a<br />

company developing this process <strong>no</strong>w<br />

– it’s really exciting.<br />
