A project to convert sewage into a zero-emission fuel is set to go ahead in Wales.
It will see biogas waste converted into hydrogen fuel, which can be used to power zero-emission vehicles.
Sewage sludge is a by-product of the wastewater treatment process - producing microbe-rich solid sewage, which can then be used as biogas fuel.
The Make Your Poo Work For You project has been awarded £60,000 by Innovate UK.
