A biogas project using waste salmon in the Outer Hebrides of Scotland has won a top environmental award. The Outer Hebrides Local Energy Hub, based on the Isle of Lewis, processes waste salmon into biogas using anaerobic digestion (AD) and won the coveted Scottish Environment business VIBES award for its innovative practices.

The project is a collaboration between the local council Comhairle nan Eilean Siar, the Scottish Salmon Company, Pure Energy Centre and Community Energy Scotland. Landia provided the pasteuriser that processes the waste salmon at the plant.

Donnie Macmillan, plant manager at Stornoway’s Creed Integrated Waste Management Facility, said: “This award is a huge achievement for such a strong and determined partnership that underlines our belief in seeing this progressive plant continuously improve – minimising, maximising and optimising the methods of managing waste.

“We must acknowledge the very professional team at Landia, whose equipment now enables us to integrate a seven-cubic tonne batch per shift of waste salmon with household food waste and garden waste for our AD process. This makes a very positive environmental and economic impact by not sending the waste salmon to landfill or having it transported off the island.

“We had very challenging space restrictions and regulations to adhere to, but from beginning to end, Landia were determined to make it work – and it certainly has.”

The VIBES awards, now in their 20th year, recognise Scottish businesses that showcase best practice, taking major steps to improve or reduce their impact on the environment.
