Anaerobic digester in Baldock converts food to electricity

A new anaerobic digester has opened in Hertfordshire, turning waste food from restaurants, factories and businesses into electricity.

The £12m recycling plant is between Baldock and Royston, on the A505.

It can process up to 40,000 tonnes of waste, converting it into methane-generated electricity.

Neil Bradford explains how it works.
