What is anaerobic digestion?

Surrey produces almost 80,000 tonnes of food waste a year, if all of this was collected from caddies, it would generate enough electricity to power 10,000 homes for a whole year.

Anaerobic digestion uses micro-organisms to break down the food waste from your caddy in the absence of oxygen to create power and fertiliser. Once all the electricity has been produced, a liquid fertiliser is left which is used in farming.
