Biofuel derived from landfill waste is to power a rubbish collection vehicle in London.The UK's largest waste management company, Veolia has announced it is launching a trial vehicle which uses compressed biomethane (CBM) produced at a landfill site.Veolia Environmental Services will add the 136bhp Iveco Daily vehicle to collect waste around London's Camden borough.Liquid biomethane specialists Gasrec are to set up a refuelling station at the Camden council depot.In between refills, the vehicle can travel 380 kilometres on a single tank.The trial is designed to test the technology to asses whether it is "commercially competitive and environmentally sound".Keith Riley, managing director for technical services at Veolia, said: "CBM has excellent potential to provide at least some of our vehicles with a fuel that reduces climate change impacts and contributes to reducing our dependence on mineral fuels. "We have to look at environmentally friendly alternatives for our operations and gas-powered vehicles are one of those developing technologies we are keen to assess."Because the fuel is generated from UK waste it will be immune to the natural gas commodity price rises which saw British Gas hike its prices 35 per cent.
