Sainsbury’s has become the first company in the world to use natural refrigerant trailers.
The prototype uses only CO2 refrigerant.
Developer Carrier Transicold claims the global warming potential of CO2 is much lower than other refrigerants such as propane and ammonia.
Two more units will join Sainsbury’s fleet this year as part of a three-year technology field trial.
Gary King, Operations Support Manager at Sainsbury’s said: “The beauty of Carrier Transicold’s prototype trailer unit is it delivers a massive reduction in F-Gases [Fluorinated] by using natural refrigerant.
“This will directly help us achieve our ambitious environmental and sustainability goals, whilst delivering a seismic leap forward in terms of sustainability within the cold chain.”
