12 Jan 2022 --- The conventional disposable coffee cup might not be as innocent as it first appears. While the thin plastic lining inside the cup holds liquid without leakage, it also renders it unrecyclable. A UK parliamentary report published in 2018 found 2.5 billion coffee cups are used and thrown away each year in the UK, but less than 1 in 400 is recycled. The Confederation of Paper Industries admitted to the House of Commons Environmental Audit Committee that “paper cups cannot be regarded as generally recyclable.”
