Opened at the end of October, the £15m Portishead store is using eCO2, the new CO2 refrigerant from A-Gas made from waste sugar beet.
With Sainsbury’s looking to reduce operational carbon emissions by 30% absolute and 65% relative compared to 2005, the retailer believes eCO2 is a refrigerant which can make an important contribution.
A-Gas operations manager Rob Parker said: “The X factor for eCO2 is the sustainable way it’s produced.
“Most CO2 refrigerants are recovered from dirty industrial processes which are far from green in their methods. eCO2 is a by-product of bioethanol production from waste sugar beet – using crops not destined for sugar production.”
