A County Durham recycling firm has been given the go-ahead to extend a scheme to turn household waste into compost.
The Environment Agency and Defra have backed plans by Premier Waste Management to treat 60,000 tonnes of waste in Thornley, near Peterlee.
The firm uses bio-processing technology to break down household waste into a compost-like material which is then used to enhance poor quality soil.
The process cuts the amount of waste sent to landfill sites by about 75%.
A company spokesman said it hoped to produce about 5,000 tonnes of soil supplement a year.
