BOC to build first CO2 purification plant in the UK

23 November 2015

BOC, a member of The Linde Group, is to build its first UK carbon dioxide (CO2) purification plant, following the signing of an agreement with leading food company Cargill for the provision of raw CO2 feedstock.

The plant will be built on Cargill's Trafford Park site in Greater Manchester and will capture and purify waste CO2 and convert it into food and beverage grade liquid CO2. The waste CO2 is a by-product of Cargill's wheat fermentation process, which produces potable alcohol for consumer products such as perfumes, mouthwash and beverages.

The facility will include 1200 tonnes of bulk liquid storage, enabling better stock management during plant maintenance periods and shortages in the wider supply network.

Julie Elders, BOC Product Manager Bulk CO2 & Hydrogen, commented: "The majority of the UK's CO2 feedstock comes from aging and increasingly unreliable ammonia plant. This means frequent product shortages, with alternative supplies having to be brought by road tanker from mainland Europe, adding cost and complexity to the supply chain. Our investment in this purification plant will strengthen and grow the UK supply network for this essential product."

Paul Kingston, General Manager Cargill Starches & Sweeteners, commented: "We are delighted to be part of this innovative project. Recycling our CO2 waste stream means that 100% of Cargill's by-products are now re-used, thus contributing to the environmental sustainability of our site."
