Human waste transformed into renewable gas to power homes

A COMPANY in Britain has begun transforming human waste into renewable gas that powers homes for the first time.

Centrica began feeding biomethane gas from sewage into Britain’s natural gas network yesterday, as the country’s biggest energy supplier seeks to trim carbon emissions.

The project will supply enough gas for 200 homes using anaerobic digestion to treat waste from Thames Water customers, Centrica said. The biogas produced is then cleaned to remove any odour and fed directly into the gas network.
