Emerald Biogas investigating gas injection for almost complete anaerobic digestion plant


A new £8 million anaerobic digestion facility in County Durham may inject biomethane into the grid once complete.

Emerald Biogas is only weeks away from commissioning the plant after securing a number of food waste contracts.


The company has revealed that it is exploring the potential of biogas injection technology as well as development of a vehicle fuel station on the site.

At full capacity, the facility will treat 50,000 tonnes of food waste providing 1.56MW of electricity to the grid.

A second phase will commence once the first plant is built to double the capacity of the facility. Planning permission has already been secured for phase two.

Emerald Biogas director Adam Warren said: “Despite the difficult winter and the associated problems it brought, we are now ready to begin testing the facility. We are confident that waste processing and energy production will begin in June and therefore we are keen to progress with the second phase.

“The next few months will see a flurry of activity on site as we gear up for phase one to become fully operations. Once at full capacity, we can look forward to creating renewable energy for neighbouring industrial companies and producing quality fertiliser from the digestate for use by the local agricultural community.”
