Food Waste to Fuels

Humans in modern societies waste more food than they can imagine. But biofuels engineers and entrepreneurs are riding to the rescue, to turn what was once waste into useful fuels and energy.
Four ReFood plants already operating in Germany currently generate energy from food collected from 60,000 points across the country, using 14 logistics centres.

Like the German network, the British version will also use collection points located across the country, supported by the network of AD plants.

Anaerobic digestion involves organic wastes or energy crops being used to feed bacteria, which under controlled conditions generate a biogas that can be put through an internal combustion engine or burned to generate heat and power.

Mr Simpson said the ReFood technology was "very advanced" compared to other AD technologies available in the UK since it was designed around using food waste as a feedstock, rather than an adaptation of technologies using sewage sludge or farm wastes.

"As a result, the ReFood system is able to focus on recycling greater quantities of this type of material," he said.

Franz Bernhard Thier, a member of the board of Saria Bio-Industries, said: "ReFood has been operating on an industrial scale successfully in Germany for a number of years. We're delighted to be teaming up with PDM to bring both our areas of expertise together to create an offering that is really going to support food waste recycling and renewable energy generation in the UK." _bioenergy
While the uninformed debate over "food vs. fuels", more intelligent persons are looking into the future for ways to convert waste from an overabundance of food -- into energy and fuels.
