Scottish renewable energy company Proactive Energy has been given the green light by the local council to build a £22.5m biogas plant.

The 5MW anaerobic digestion (AD) plant is part of the M74 eco-park, between Glasgow and Carlisle.

The plant will use the AD process to generate electricity. This involves methane-rich biogas generated using bacterial cultures on organic waste within enclosed silo tanks.

The captured biogas will then be used to fuel engines, which generate renewable electricity that can be fed into the National Grid.

Proactive Energy is the first company which has signed up for the M74 eco-park, where construction work is scheduled to start by April 2010.

The plant, which is expected to begin operation by early 2011, should generate sufficient electricity to power 2,500 homes and create ten permanent jobs.
