Finally found it
The new fuel pellets, which have been designed from scratch - over a two and a half year research and development programme, involving some of the world leading combustion experts - have been specifically engineered to deliver high energy content (calorific value of c. 20GJ/MT) and significantly lower carbon and NOx emissions, compared to coal. At a cost of just £4/MT, these waste-derived fuel pellets are significantly lower cost than both coal - which they are replacing – which costs c. £70/MT, and biomass wood pellets, which cost c. £100/MT.” taken from Arden report well worth a read
