Compared with the existing chemical cleaning system, the new one will result in the continued reduction of carbon emissions and drive down operational costs for the distillery.
Alpheus already operates and maintains the wastewater treatment plant for the distillery, which produces the world-renowned single malt whisky. The green biogas cleaning system will be integrated into the existing distillery’s Anaerobic Digestion (AD) plant. AD is a process through which bacteria breaks down the by-products of whisky production, turning them in to biogas which is used to generate clean green energy.
The overall treatment process also has a positive impact on water quality and biodiversity, with the treated effluent from the AD plant acting as a highly nutritious food for oysters to feed off and further enhance the water quality.
This has led to the long-term restoration of a native oyster reef located in the Dornoch Firth beside the Distillery. The DEEP (Dornoch Environmental Enhancement Project) has successfully improved the biodiversity of and quality of the coastline, reintroducing more than 20,000 of the molluscs back to the seabed in just four years.
