New contracts from both Perth and Kinross and Nottingham City councils have been awarded to TEG Group.
The company has won a £2 million contract to treat between 20,000 and 25,000 tonnes of garden and food waste from Perth and Kinross Council.
While Nottinghamshire City Council has given TEG a contract worth over £1 million for green waste composting.
For Perth and Kinross, TEG has been dealing with the garden waste for several years, but this is the first time it has been contracted to treat food waste on a standalone basis.
Though initial volumes will be small, it hopes to treat the waste at its anaerobic digestion plant at Binn Farm.
This AD plant was commissioned last year costing £4.5 million by TEG Biogas Perth in partnership with Albion Venture with further support from Zero Waste Scotland.
It is capable of handling 15,000 tonnes of food waste per year to generate 0.7MW of electricity and 0.2MW of heat.
TEG chief executive Mick Fishwick said: “We have been working with Perth and Kinross Council for many years and we are delighted to have been awarded this new contract which will enable us to further strengthen our relationship with the council.
“It is exciting that the contract includes food waste as a new waste stream and that waste will be converted into renewable power and fertiliser in our AD facility.”
