Biogen Ltd, a specialist in food waste-to-power, sees growing opportunities for anaerobic digestion combined heat and power (CHP) in the UK as landfill taxes rise.

Over 2013, Biogen aims to start building four or five CHP plants, doubling its annual waste processing capacity up to 200,000 tonnes of food, CEO Richard Barker told Bloomberg.

UK landfill tax climbed last year to £64 ($101) a tonne but it is set to hit £72 ($114) on 1 April.

Biogen has just announced that a five-year contract to generate heat and power from food waste from the town of Peterborough, in eastern England.

Under the contract, Biogen’s Westwood anaerobic digestion plant will process 6000 tonnes of waste each year, feeding electricity to the grid, using heat in its process and generating biofertiliser.

Earlier this month, the firm announced a 2.5 MW project in Hertfordshire, in southern England.

Organic waste processed at waste-to-energy anaerobic digestion plants reached 1.1 million tonnes in 2010, according to a report from the Waste and Resources Action Programme (WRAP) last year.
