Food waste fuels vehicle

Resource management company GENeco has launched a vehicle, known as the Bio-Bee, that collects and runs on commercial food waste in Bristol, UK[2].

The Bio-Bee’s total carbon footprint is reported to be around 90% lower than a diesel equivalent and it is quieter than standard diesel models. The new vehicle is also intended to engage youngsters in the topics of food waste, recycling and air quality.

Food waste is collected in the Bio-Bee and brought back to GENeco’s anaerobic digestion plant in Bristol. The waste is depackaged and plastic is removed. The remaining food waste undergoes a pasteurisation process before being fed into the anaerobic digesters, where micro-organisms break down the waste in the absence of oxygen and produce methane-rich biogas. This biogas is either used to produce renewable electricity or it is converted in a gas-to-grid plant to enriched biomethane, which is injected into the gas grid. At this stage it can be used as fuel in the Bio-Bee and other vehicles or to supply local homes. The solid by-product of the anaerobic digestion process is used as a nutrient-rich and sustainable biofertiliser for farms.

Boston Tea Party and St Monica Trust care homes are among the first companies to use the service, and it is hoped that the Bio-Bee will increase food waste recycling levels in the city.
