The Anaerobic Digestion and Bioresources Association (ADBA) has called on the Government to push ahead with plans to increase the amount of biofuel derived from waste used in the transport sector.
In November last year, transport minister John Hayes said he wanted to boost investment in waste-based and advanced fuels.
Proposals on new targets within the Renewable Transport Fuel Obligation (RTFO) to increase the percentage of biofuel derived from waste other than used cooking oil by up to 30% were published by the Government.
Under the RTFO, transport fuel suppliers producing more than 450,000 litres a year are required to ensure that a proportion of the fuel they supply comes from renewable biofuels.
But although a consultation on the target ended in January, no firm policies have yet been produced. The Conservative manifesto for the General Election includes a pledge to invest £600m in electric vehicle technology, but does not specifically mention biofuels.
ADBA said the domestic AD industry has sufficient capacity to produce enough biomethane to power more than half of the UK’s entire bus fleet.
Chief executive Charlotte Morton said: “During the short to medium term, biomethane presents the only practical means of decarbonising HGVs, buses and non-road mobile machinery.
“While biomethane has the potential to power every HGV in the country, and some pioneers have grasped this opportunity, far more support is needed from the Government to make it easier for others to follow their example.
“It is critical that the new Government urgently delivers a robust response to the RTFO consultation that concluded in January.”
Morton’s comments come as Nottingham City Transport launched its £17m biomethane bus fleet.
Engineering director Gary Mason said: “We are hugely proud of our new biogas buses. This is the largest order for gas double-decks in the world and is the culmination of our extensive research into alternative fuels.”
