Designer tobia zambotti calls attention to the harmful environmental effects of single-use mask pollution with the design of ‘couch-19’, which has been symbolically shaped to resemble the irregular form of an iceberg. to help prevent the spread of COVID-19, face coverings have become a requirement in public spaces throughout the world. many face masks available for sale are made from layers of plastics, and are designed specifically to be single-use. since they are considered medical waste and cannot be recycled through conventional recycling facilities, masks — and their widespread litter on the streets — pose a threat to the environment.
