Tesco plans to end contracts with third-party brands using 'excessive and non-recyclable plastic packaging' from 2020.
Chief executive Dave Lewis says the contracts, due to start next year, will include a new clause to 'reserve the right not to list' certain items because of their packaging.
Mr Lewis told The Guardian: “Over the last year we’ve changed the packaging for 800 Tesco brand products, removing 4,000 tonnes of hard-to-recycle packaging.
"By the end of this year, we will have removed the hardest-to-recycle materials from Tesco products and are working with our branded suppliers to do the same.
"We have all looked at the settled contents of a cereal packet and puzzled over the comparative size of the bag and box. Or opened a bag of crisps and wondered why the packaging is twice the size of the contents.
"This month, we brought together our partner suppliers to look for truly efficient solutions, ones that might require different materials and new designs.
"In some cases, it will mean going back to the drawing board."
