Case Study: North British Distillery
The North British Distillery Company was established in 1885 making it one of Scotland’s oldest and largest whisky producers. Today, manufacturing whisky is a heavily regulated industry and NBD are bound by various forms of legislation and must adhere to strict environmental protocols.

North British Distillery
NBD’s Edinburgh site installed a 500kW AD plant in 2010, which converts the liquid residues (waste) from the grain whisky process into Biogas. The Biogas fuels an engine which drives an alternator that generates up to 450kW of electricity. All electricity generated is used on site.
The Challenge
- Maximise revenue potential from the operation of their Anaerobic Digestion (AD) Plant
- Maximise environmental benefits of operating the AD plant
The Solutions
- Ensure the plant qualifies for and receives all available subsidies
- Assess how any waste heat from the AD plant canbe utilised in the distilling process
The Benefits
- Additional revenue of £280,000 p.a.
- Waste heat is now fully utilised to produce steam, fulfilling NBD commitment to Scottish Environment Protection Agency
Making it pay
By utilising the waste residue NBD avoided paying waste removal costs, but that alone wouldn’t make the plant economical to operate. Trident’s experienced staff managed to get the plant Ofgem accreditation entitling NBD to receive Feed-in-Tariff (FiT) subsidies. Trident manage the on-going monthly reporting and data submission process, monitoring the output levels to ensure NBD continue to receive annual payments of £224,000 for the next 25 years.
Protecting the Environment
NBD have a commitment to the Scottish Environment Protection Agency to reduce their impact on the environment. Trident looked at ways to utilise the waste heat generated by the engine. By connecting a waste heat boiler to the back of the engine, steam is now generated and used in the distilling process. Trident assessed both technical and financial considerations to determine the viability of the project. By advising on certain design aspects of the installation, Trident maximised efficiencies and ensured qualification for the Renewable Heat Incentive Scheme. This secured a further income stream of £56,000 per annum guaranteed for the next 20 years.
