Turning sludge into power

Northumbrian Water’s award-winning anaerobic digestion plant at Howdon on Tyneside produces biogas from sludge – the byproduct of the sewage treatment process.

The gas is currently used to generate electricity, but Northumbrian Water is now working to upgrade and purify the biogas into biomethane, so it can be injected directly into the grid.

We are working closely with the water company on this exciting project.
