Mae'r cwpanau'n anodd eu hailgylchu - maen nhw wedi'u gwneud yn bennaf o bapur wedi'i leinio â phlastig ac wedi'u baeddu. Ar hyn o bryd dim ond tri chyfleuster ailgylchu arbenigol sydd yn y DU sy'n gallu eu prosesu. Mae hyn yn golygu mai dim ond cyfran fechan o gwpanau coffi untro sy'n cael eu gwaredu'n gywir a'u hailgylchu.
The cups are difficult to recycle – they are largely made from paper lined with plastic and soiled. There are currently only three specialised recycling facilities in the UK which are able to process them. This means that only a small fraction of single-use coffee cups are disposed of correctly and recycled.
