RENEWABLE TRANSPORT FOOD AND FUEL FROM FARMS AND WASTES TO CUT CARBON AND BOOST AIR QUALITY


Renewable fuels can provide an improvement in air quality and a reduction in carbon emissions immediately without the need for extensive new fuelling infrastructure or vehicle conversions, and at minimal cost (about £9.00 per year according to the DfT) to the consumer. The most common forms are:


Bioethanol - can be blended into petrol. It is made from starch-based biomass feedstocks - usually from sugar cane, wheat, maize and sugar beet and increasingly from municipal solid waste and agricultural residues.


Biodiesel - can be blended into diesel. It is produced from oil-based feedstocks - traditionally oilseed rape, soy and increasingly waste streams such used cooking oil (UCO) and tallow. The UK market is mostly supplied by waste-derived biodiesel.

Biomethane - can be used in gas engine vehicles, either direct from a biogas fuelling station or indirectly from the gas grid using the Green Gas Certification Scheme. It is upgraded biogas from anaerobic digestion or thermal processing of food waste, farm slurries and energy crops.


Producing these fuels in the UK has additional benefits: - Providing investment and skilled jobs to the UK economy - Waste-derived fuels reduce landfill


- Processing locally grown wheat into bioethanol produces equal weights of protein rich animal feed that replaces imported soy meal
