Northampton-based baker Oliver Adams is sending its food waste to be turned into energy, in addition to its existing recycling programme.

Instead of paying £40 per tonne to send its food waste to landfill, waste management company F&R Cawley is now picking it up and sending it for mixing with pig muck for feeding into a biogas plant.

Oliver Adams produces several tonnes of food waste a week from its 28 shops, said MD Thomas Adams. "I am no tree hugger but I can see a great deal of benefit in using waste to generate electricity and for other products."
