Researchers at the University of Sunderland say the project aims to identify and develop more energy efficient refrigeration technologies and business practices for use throughout the food chain.

The resulting techniques will not compromise on food safety and quality, they claim. The research is being funded by the UK's Department of Environment, Food & Rural Affairs (Defra).

David Baglee, who is leading the research team, says Sunderland's role will be to concentrate on research into business practices and how the application of these would improve energy efficiency.

"Problems can be anything from poor maintenance practices, to something as simple as employees forgetting to close the freezer door," he said. "But inefficient refrigeration can be a massive cost, both in terms of your business and, of course, the impact it has on the environment."

Sunderland is working with Bristol, Brunel and London South Bank universities on the project over the next two years.

"The team will investigate improved maintenance techniques, new refrigeration technologies, and techniques such as value stream mapping to save money, time and energy," Baglee said.
