Disposable surgical masks have now joined the list of 18 materials already recycled on Le Rosey’s campus. Collection boxes, which also serve as hygienic containers for used masks, can be found in each of the boarding houses as well as in the Carnal Hall to encourage the whole Rosean community to play their part in limiting the environmental impact of current sanitary measures. This initiative is led by Transvoirie, a branch of Helvetia Environnement, and was launched in French-speaking Switzerland on 1^st April 2021; it recycles single-use masks back into polypropylene granules to be used in the production of plastics, construction or automobile parts.
