Coffee cups are made from paper... So what's the problem?
Disposable coffee cups are lined with plastic polyethylene which enables the cups to be waterproof and therefore hold liquid.
However, once the cups have held liquid they cannot be recycled at a normal recycling plant and must instead be taken to a special facility.
In reality, only 1% of disposable coffee cups make it to this facility which is why the UK government is enforcing what will be known as the "Latte levy". A 25p tax on all single-use cups.
Do you drink 1 coffee a day? Switch to a reusable cup and in little over a month it will have paid for itself. Problem solved.
Disposable coffee in numbers:
7 Million - The amount of coffee cups used daily in the UK
>1% - Amount of disposable coffee cups that are actually recycled
25p - The "Latte" Levy
