Wensleydale Waste to Heat 4,000 Homes

The crumbly cheese beloved of TV duo Wallace and Gromit will soon help heat thousands of Yorkshire homes with renewable “green gas” made from cheese waste.

The Wensleydale Creamery has struck a deal to supply the waste whey from its cheese factory to a local bioenergy plant that produces enough renewable biogas to heat 4,000 homes. The Leeming biogas plant, which currently runs on ice-cream residue, will use a process called anaerobic digestion to turn the dairy-based waste into renewable biogas.

This process has been used since the 19th century to capture gases that are created naturally when food waste breaks down. Modern anaerobic digestion plants can inject the gas directly into the local gas grid, and can produce bio-fertiliser too. The project helps tackle a triple sustainability challenge for the UK by shrinking the carbon footprint of energy and reducing waste while helping to develop sustainable farming practices.
