GENeco is part of the Wessex Water group of companies and operates sewage treatment works. It recycles waste, produces renewable energy and provides the agricultural industry with fertiliser. In summer 2010, GENeco launched the Bio-Bug, a modified VW Beetle that runs on bio-gas generated from waste treated at sewage treatment works. Waste flushed down the toilets of just 70 homes in Bristol is enough to power the Bio-Bug for a year, based on an annual mileage of 10,000 miles. In November 2014, the UK's first bus powered entirely by human and food waste went into service between Bristol and Bath, run by tour operatorBath Bus Company. The biomethane gas is generated at Bristol sewage treatment works in Avonmouth, which is run by GENeco.
