Last week, Morrisons revealed it has become the first supermarket to offer its customers a way to recycle coffee pods through a partnership with the recycling scheme Podback.
Over the coming weeks, Morrisons customers will be able to pick up free Podback Collect+ recycling bags from its customer service desks.
The Podback bags can be filled with used coffee pods at home, then taken to one of 6,500 Collect+ delivered by Yodel drop off points around the UK. All postage back to Podback is free.
Lorraine Wheeler, Environmental Packaging Manager at Morrisons, said: “Many of our customers want to brew fresh coffee at home using a coffee pod. But to date, coffee pod recycling has been confusing for consumers, with several different schemes by multiple brands. Podback offers an easy, simple scheme for all of our customers.”
