In order to ensure that disposable cups conform to health and safety requirements, they are made with paper fibre and a 5% polyethylene lining which is bonded together under a high heat. This use of mixed material ensures the strength and safety of the cups, but it renders the cups difficult to recycle. Although both the paper and plastic components of disposable cups are recyclable, the materials need to be separated out, which is a more complicated process than traditional paper is recycling.
While disposable coffee cups are recyclable in specialist facilities, they are not currently widely recyclable in most local authority recycling centres. That means they need to be disposed of and collected seperately from all other waste to be recycled. There are currently only three recycling facilities in the UK which have the ability to recycle coffee cups; James Cropper PLC, ACE UK and Veolia.
