Householders to get gas from human waste

Householders in Didcot have become the first in the UK to use gas made from their own human waste and supplied via the national grid to heat their homes.
Centrica has supplied up to 200 Oxfordshire homes with biomethane made from sewage flushed away three weeks earlier.
British Gas, Thames Water and Scotia Gas Networks now hope to roll out the process across the UK.
John Gilbert from Didcot Renewable Gas Project explains how the plant works.
