Chivas Brothers Ltd, Longmorn Distillery: Mechanical Vapour Recompression (MVR) System
- SIETF grant offered: £1,813,994
- project cost: £6,046,600
- deployment competition
- local authority area: Moray
Company business
Chivas Brothers Ltd is a whisky distiller with various sites across Scotland and is part of the wider Pernod Ricard group.
Technology summary
The project aims to improve energy performance and reduce carbon emissions by installing advanced heat-recovery and process-optimisation technologies. It involves a Mechanical Vapour Recompression (MVR) system to reduce energy use and carbon emissions through increased use of electrically-driven heat-efficient distilling processes. The project involves installing four MVR units on the wash stills at Longmorn Distillery. These units will recover vapour energy, reducing direct steam demand.
Emission savings
The company states that this project will achieve reductions of approximately 2,048 tCO₂e per year, validated against comparable distillery applications.
Iomart Managed Services Limited: Free cooling system (Mechanical Cooling)
- SIETF grant offered: £297,291
- project cost: £990,972
- deployment competition
- local authority area: Glasgow City
Company business
Iomart Group plc is one of the UK's leading providers of secure cloud managed services, simplifying the complexities of modern technology for businesses, with the majority of Group revenue derived from the UK. A team of 600+ deliver cutting-edge solutions in cloud infrastructure, modern workplace management, and managed security services that enable customers to innovate, protect, and scale their businesses.
Technology summary
This project involves deploying a high-efficiency hybrid cooling system at Iomart’s Glasgow data centre. It aims to improve the existing direct-expansion computer room air conditioning units with Hybrid and Free-Cooling CRAC Units.
Emission savings
Since Iomart already uses low-carbon power (about 50 gCO2 per kWh). This project states an annual reduction in CO₂ emissions of 35% compared to existing, or 46 tCO₂e per year.
The North British Distillery Company Limited: Wet feed offloading system (Moist Distillers Grains).
- SIETF grant offered: £482,669
- project cost: £965,398
- deployment competition
- local authority area: Edinburgh City
Company business
The North British Distillery Company makes Scotch grain whisky, which is used as the base for blended Scotch whisky brands. The company also produces valuable by-products, including animal feed and products for AD plants.
Technology summary
This project focuses on expanding the company’s Moist Distillers’ Grains (MDG) offloading process to lower energy use at the site. The trial phase is finished and included building a loading bay to allow direct sales of MDG.
Emission savings
The company states that this project will cut net emissions by 5,326 tCO₂e per year which covers an increase of about 1,000 tCO₂e from extra vehicle trips needed to move the wet by-product to market. The data also show that removing the drier system will lower electricity use by 4,106 MWh per year.
The North British Distillery Company Limited: Biogas Production and clean effluent (Anaerobic Digestion and Water Treatment Plant).
- SIETF grant offered: £1,267,661
- project cost: £2,582,356
- deployment competition
- local authority area: Edinburgh City
Company business
The North British Distillery Company makes Scotch grain whisky, which is used as the base for blended Scotch whisky brands. The company also produces valuable by-products, including animal feed and products for AD plants.
Technology summary
The project involves the reinstatement and upgrade of the on-site anaerobic digestion and water treatment plant (AD and WTP) which was constructed in 2010 but subsequently taken offline due to operational issues.
Key elements of scope include installing a new Dissolved Air Flotation (DAF) system with screw press dewatering, replacing the lime plant for pH control, upgrading the biogas boiler to dual-fuel, recovering spent Clean-in-Place, and modifying pre-acidification tanks.
The project will also divert a portion of the decanter concentrate from evaporators into the WTP. The project intends to generate renewable biogas for heat and power while improving effluent quality for discharge.
Emission savings
The company states that expected energy savings are 3,900–6,800 MWh per year, equivalent to 770–2,395 tCO₂e per year of emissions savings.
Syngenta: High shear mixing
- SIETF grant offered: £225,000
- project cost: £450,000
- deployment competition
- local authority area: Falkirk
Company business
Syngenta Ltd operates a major manufacturing facility in Grangemouth, producing crop protection products and agricultural chemicals. The site is one of the company's key global manufacturing hubs, employing advanced industrial processes in the production of essential agricultural solutions, including pesticides, herbicides, and fungicides.
Technology summary
The project plans to use inline, variable-speed, high-shear mixing technology in the manufacturing process. This advanced mixer allows the use of granular reagents, which helps save energy, improve processes, and boost product quality, while also cutting down on raw material use. The system uses a rotor-stator setup, in either a bath or inline arrangement, to create strong shear forces that emulsify, blend, or disperse materials.
Emission savings
The company states that this technology is expected to reduce emissions at Grangemouth by approximately 900tCO2e per year, with the potential to expand this reduction by 3500tCO2e per year if high-shear mixing were applied to other processes at the Grangemouth site.
Aquascot Ltd: Design of a new processing facility to enhance energy efficiency.
- SIETF grant offered: £45,000
- project cost: £75,000
- study competition
- local authority area: Highlands/Alness
Company business
Aquascot is a Scottish seafood company that processes and supplies responsibly farmed salmon and trout. It develops high-quality fish products for retail, including fresh and prepared dishes.
Technology summary
This feasibility study and design project for the new processing facility will help Aquascot to meet its decarbonisation goals. The planned changes will greatly lower energy use and carbon emissions at the Alness site.
The proposed project will include facilities for processing farmed fish products for supermarkets. Existing facilities have poor energy efficiency, including temporary buildings and outdated refrigeration equipment. The new facility will enable the implementation of measures outlined in the company’s Net Zero Pathway to enhance energy efficiency, including waste heat recovery from refrigeration systems, solar photovoltaic (PV) and battery installations, improved insulation, enhanced metering, and building management system (BMS) upgrades.
Emission savings
The study project states that the new facility and proposed low-carbon technologies are expected to cut annual emissions by 331 tCO2e per year.
John Dewar and Sons Limited: Heat electrification solutions
- SIETF Grant Offered: £51,178
- project Cost: £102,357
- study competition
- local authority area: Perth and Kinross
Company business
John Dewar and Sons Limited is a whisky producer with various sites across Scotland and is part of Bacardi Limited.
Technology summary
This project will carry out technical feasibility studies at three John Dewar and Sons Limited malt whisky distilleries: Aberfeldy, Aultmore, and Royal Brackla. The goal is to find practical ways for each site to reduce carbon emissions, helping the company to reach its goals of Net Zero Carbon in direct operations by 2040 and across its value chain by 2050, targets approved by the Science Based Targets initiative.
Emission savings
The feasibility studies will assess a range of heat and energy technologies to determine their technical, financial, and operational viability. A key aim is to quantify the potential for carbon savings and energy efficiency improvements, with preliminary analysis suggesting that significant site-wide energy efficiency gains may be achievable. These improvements are expected to be realised through the retrofitting of advanced technologies such as mechanical vapour recompression, high-temperature heat pumps, and thermal energy storage systems.
