Sainsbury’s trials greener trailer

Sainsbury’s is trialling the world’s first naturally refrigerated trailer to transport chilled and frozen food.

According to the supermarket chain, the new technology could save more than 70,000 tonnes of C02, which is the equivalent of taking 34,000 cars off the road.

The technology has come from Sainsbury’s two-year partnership with shipping container refrigeration company Carrier Transicold. A modified version of its NaturaLINE refrigeration system, which was created for deep sea containers, is being used.

The trial, which is part of Sainsbury’s review to reduce its carbon footprint, will see the company convert all its stores to the new natural refrigeration by 2030. All of Sainsbury’s refrigerated depots are operating with natural gas and 160 stores have also moved to the system.

Sainsbury’s head of transport operations Nick Davies said: “The new carbon dioxide technology has much less of an impact on climate change and we hope it will play a big part in helping us reduce our carbon emissions. We will be monitoring its performance closely.”

Of the trial and its partnership with Sainsbury’s, president of Carrier Transicold David Appel said: “This is the very first time that our NaturaLINE system has been mounted to a box trailer anywhere in the world. It’s also much better news for the environment because natural refrigerant CO2 is non-ozone depleting and has a global warming potential (GWP) of one.”
