Sainsbury’s is set to heat 100 of its stores with recycled heat from its refrigeration systems using pioneering new technology.

Working with a firm called Geoscart, the retailer will save the heat produced in the refrigeration process, which would otherwise be lost as waste, and use this in its store’s heating systems, cutting energy consumption by more than 30 per cent.

The technology works by piping the heat from fridges and storing it underground using subsurface rock, which has good insulating properties, before pumping it back into the store.

Paul Crewe, Head of Sustainability, Engineering and Energy at Sainsbury’s, said: “We’re delighted to be leading the way on this groundbreaking technology – helping to reduce energy use and carbon. I hope that with Geoscart’s help we’ll now see more retailers following suit.”

In other news, Sainsbury’s has reportedly taken out a first of its kind green loan to fund energy efficiency, renewable energy and water saving projects over the next two to three years. The Grocer reported that the £200m loan with Lloyds Bank and Rabobank to invest specifically in sustainability initiatives is a market first in the UK.
