Carbon dioxide (CO2) does not always enjoy the best of reputations. But we should not forget that liquid carbon dioxide (LCO2) plays an important role in the food and beverage industry – for example freezing pizzas, making soft drinks sparkle and keeping packaged foods fresh. CO2 is recovered from the unwanted off-gas streams emitted by processes such as fertiliser, plastics and food production. Captured, purified and then usually liquefied, it is ultrapure and ideal for use in foodstuffs.
Until recently, BOC did not have its own LCO2 production plant, using third-party suppliers instead. Leading food company Cargill made CO2 which it had no use for as a by-product of its manufacturing processes. Spotting a mutually beneficial opportunity, the two companies formed a partnership which resulted in the recent opening of BOC’s first UK CO2 purification plant at Cargill’s Manchester site.
