Glenmorangie Distillery to install biogas cleaning system with Alpheus

Alpheus Environmental will implement a biogas cleaning system at the Glenmorangie Distillery in Scotland.

The new biological cleaning system will substantially reduce the use of chemicals to clean biogas, a by-product of the distillation which mainly consists of CO2 and methane. Compared to the existing cleaning system, this will result in the continued reduction of CO2 emissions and drive down operational costs for the distillery.

The green biogas cleaning system will be integrated into the distillery’s existing anaerobic digestion (AD) plant. Alpheus already operates and maintains Glenmorangie’s wastewater treatment plant.

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 in the Dornoch Firth beside the distillery.

“We are delighted to be implementing this green biogas cleaning solution, supporting Glenmorangie in the production of some legendary whiskies and assisting them in operating their plant in the most sustainable and efficient manner,” said Declan Maguire, managing director at Alpheus Environmental.

“In addition to protecting the Dornoch Firth, the recovery of the energy from the treatment process feeding back into the distillery makes it highly sustainable and beneficial for the environment.

“We greatly welcome the opportunity to work with Glenmorangie to deliver further efficiencies for this business over the coming years, delivering a clean, green future.”

The Scotch Whisky Association’s new sustainability strategy aims to reduce the environmental impact of Scotland’s national drink, by committing the sector to reaching net-zero emissions in its operations by 2040.

Peter Nelson, operations manager at Glenmorangie, commented: “Events such as COP26 continue to reinforce the need for a sustainable future, and the whisky industry can lead in this transformation by setting an ambitious target to be net-zero by 2040.

“Working with our environmental partner, Alpheus, is key to achieving our sustainability targets, mitigating the impacts of climate change, and ensuring that we make an overall positive impact on the environment around us.”
