The Value of Chip Fat
In one rather unexpected outcome of the recent Tory leadership battle, chip shops and restaurants have been told by David Cameron to collect their old cooking fat so that it can be used to fuel cars.
The chip fat proposal is being promoted by John Gummer, he of the "safe burger" claim in the 1980's, whom Mr Cameron has appointed one of the chairmen of the group overhauling the party's environmental policies.
Gummer claims that more than 75% of the 300,000 tons of waste fat produced by restaurants in Britain each year "goes down the drain, where it has a terrible effect on sewers".
However, the fat can easily be turned into an eco-friendly substitute for diesel. Gummer goes on to claim that it is even greener than other biofuels, since it causes the emission of much less carbon dioxide.
