Residents can recycle their Christmas cards at Sainsbury’s Pontllanfraith until Monday, January 8.
The supermarket will recycle all collected Christmas cards and make a donation to the Forest Stewardship Council UK based on the volume collected in all its stores.
Sainsbury’s Pontllanfraith store manager Kim Jon said: “We’ve always had a brilliant response from customers and we hope to collect even more cards this year.
“The recycling initiative is a great way to support the invaluable work of the FSC and help customers to tackle Christmas waste and put it to positive use.”
Collection boxes will be at the front of the store and customers can also have their cards collected from their own homes when they receive their online shop.
