Hopefully you are fortunate and don’t have regular medical prescriptions! However if you do, then each time you finish a pack it should go in your wastebin, to subsequently go to landfill. As the blister packs are made from rigid plastic sides with aluminium foil they require specialist treatment. Terracycle is a group that specialises in dealing with ‘difficult to recycle’ packaging and can organise this. I was concerned about the final destination of the items they collect but it would seem they carry out due diligence to ensure their contractors are doing what they say!
Locally the packs can be taken to Superdrug in Guildord for collection by Terracycle. Clearly it makes more sense to take a large amount there, rather than making individual journeys. Terracycle make a small donation to Marie Curie Foundation during the process. I have a collection box on my front doorstep (5 Duncombs Cotts GU8 4DB) and also a box next to the telephone kiosk by Hambledon Village Stores, and am happy to make the journey to Guildford when I have several sacks full! So please save those packs and drop them in when passing – a little more plastic and aluminium reused and prevented from entering landfill!
