Morrisons has started packing some of its organic produce in biodegradable and compostable plastics film.

It follows Sainsbury's decision to use green packaging for 500 lines including ready meals with the aim of saving 4,000 tonnes of fossil-based plastics a year.

Morrisons said it was looking to extend this packaging solution to other lines. "Our fresh food Market Street offers many loose items, enabling our customers to buy as little or as much as they need with minimal packaging," said a spokeswoman.

Packaging supplier Natura ASP said the concept was set to spread through the food and drink industry. "Compostable packaging is starting to move forward," said sales director Alan Campbell, "Consumers are now telling supermarkets that they are interested in this as they want to be more environmentally friendly."

Asda is planning to introduce biodegradable packaging on organic food lines by this spring.
