Palm, soya, wood, animal fat – the list of possible feedstock for biofuels is virtually endless. They can even be made from inedible waste products, thus reducing landfill and possible conflicts with food production.
In November last year, British environmental campaigners Andy Pag and John Grimshaw set off on a journey from London to Mali in a lorry powered by chocolate waste. “We wanted to inspire other people”, says Mr Pag. “We thought that, if we can get to Mali with our lorry, then maybe some people would go: ‘That’s interesting, maybe I should look into that a bit more’, and then hopefully that would get more people to use biofuels.”
Mr Pag is already planning his next adventure for the summer. The “Grease to Greece Challenge” will see about 100 biofuel enthusiasts set off for Athens in diesel cars powered by cooking fat “which will have to be scavenged from chip fryers and schnitzel shops en route.”
“The challenge”, Mr Pag explains, “is to ‘fat-find’ your way from the UK to the Mediterranean without fossil fuels, and The Golden Lard Award awaits those that make it all the way on waste vegetable oil.”
