There's no Net Zero without Biogas: ending waste, delivering the circular economy, tackling the climate crisis.

Biogas from Fish Waste – VIBES Award for Waste Salmon AD Plant

Producing biogas from fish waste might not seem like a big deal to mainlanders, but it truly is a big deal on an island with a lot of salmon farms.

The alternative of placing this waste in a landfill would go against all Scottish, UK and EU policy at a time when climate change and the stark reality of methane emissions are in urgent need for action.

Scotland is phasing out the disposal of all organic waste to landfill, and incineration is an energy consuming option for such high water content wastes. So, without projects like the one featured in our sponsor's Press Release below it's difficult to see how without this biogas from fish waste opportunity, these islanders would be able to cope with this waste.

At this biogas plant waste salmon is co-digested with the local town of Stornoway's household food waste and garden waste.

Why this is Important:

The anaerobic digestion plant makes a very positive environmental and economic impact by not sending the waste salmon to landfill or having to transport it off the island. Indeed, the very notion of tons of fish-waste sitting on the ferry in containers, next to cars and passengers would be enough to deter much needed tourism!

Besides, this process produces biogas from fish waste. The biogas is renewable energy which reduces demand for carbon emitting fossil fuel.

Why this Needs a Pasteuriser:

Big problems can arise such as “Foot and Mouth disease”. To avoid that, the output from the fish waste biogas plant must be heated up and held at a predetermined temperature. That's done in the Landia pasteuriser producing a natural fertiliser.

Without that pasteuriser there could be no biogas from fish waste on the island. Without it there would be a lack of hygiene and the risk of spreading infection. That's why Landia's support is so important to this scheme.

The Landia Press Release (21 November 2019) follows:

Sustainable success with Waste Salmon for biogas as Outer Hebrides wins top Environmental Award

A Landia pasteuriser that processes waste salmon for an AD/biogas plant on the isles of Lewis and Harris, near Stornoway has helped the Outer Hebrides Local Energy Hub (OHLEH) win the prestigious Scottish Environment Business VIBES award.

Comhairle nan Eilean Siar (CnES) together with its partners The Scottish Salmon Company (SSC), Pure Energy Centre PEC), Community Energy Scotland (CES). Working together has ensured OHLEH was recognised as a great example of local collaboration. An example that could act as a blueprint for national best practice, not just in the salmon farming industry but across many other sectors.

Donnie Macmillan, Plant Manager at Stornoway’s Creed Integrated Waste Management Facility (IWMF), commented:

“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”.

He added:

“We must acknowledge the very professional team at Landia, whose equipment now enables us to integrate a 7-cubic ton 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 work it certainly has”.

Now in its 20th year, the VIBES recognise Scottish businesses which showcase best practice, taking significant steps to improve or reduce their impact on the environment.

The awards encourage the efficient use of resources, strive to improve environmental performance and support sustainable development including social benefits through involvement with the local community.
