I checked out the details on the packet and they have joined with TerraCycle to "upcycle" the refill packs and turn them into shopping bags, umbrellas and more! They even will give 2p per packet you return to a charity of your choice - I have chosen Macmillan Cancer Support, plus you can print off a Freepost label! A Win win situation. When I have returned 3 packets I could order a pencil case or 6 packets for a shopping bag, so helping the environment by using that rather than plastic carrier bags and saving the landfill by recycling. My packet is ready to post off to Terracycle - which incidentally does recycle other products and you can join with others to raise money for schools and groups.
