In accordance with an analysis by scientists at University College London, if each individual in the UK used one single-use masks each day for a 12 months, an additional sixty six,000 tonnes of contaminated plastic waste would be created. The use of reusable masks by the general population would significantly reduce plastic waste and the local weather change impact of any policy requirements for the wearing of face masks, according to the UCL group, led by Prof Mark Miodownik.
