It is working towards making all own-label packaging reusable, recyclable or compostable by next year.
Plastics and Packaging Director at Aldi UK Richard Gorman said: “We know our customers are environmentally-conscious.
“And as a responsible retailer, we are always striving to reduce plastic waste wherever possible.
“Our latest trial is another step in the right direction as we work towards being able to offer shoppers an option to bring problem plastic back to our stores that might not be recycled by their local councils.
“We will be monitoring the trial closely, and we hope that customers bring back their ‘soft’ plastics to our collection bins so that we can look at expanding this into more stores to help customers recycle.”
