If you have the machine, and the cup is in pristine condition (ie: hasn’t been used).

Outside those conditions, “disposable” coffee cups of all types lead to long-term pollution.

The standard paper coffee cups are about 92% paper and 8% PE for the waterproof lining. Come compostable cups have a lining made from a form of PLA and are, in theory, compostable under the right commercial conditions.

The PE lined cups can be recycled, the UK currently has capacity to recycle all the 2.5 billion cups we use annually.
