LED lighting could help cut food waste

Changing the lightbulbs could help supermarkets reduce the estimated 300,000 tonnes of food waste they produce each year, according to one lighting company.

Welsh firm Sedna LED reckons illuminating fresh produce with lightbulbs that emit heat causes food to sweat in its packaging, contributing to the food waste mountain that costs retailers millions of pounds each year.

As a result, the company is arguing that in addition to cutting energy bills, LED lights could also help keep food fresh.

“Unlike conventional lighting, LED lighting does not emit heat or any UV or IR rays, so food stays fresher for longer,” the company said in a statement. “LED light sources can be placed in close vicinity to food for an enhanced aesthetic effect, but with no danger of premature food deterioration.”
