CTT joined the mask recycling project, created by TO BE GREEN, a spin-off of the University of Minho. The project, which illustrates the concept of a circular economy, aims to reduce the environmental impact associated with the use of anti-COVID protective masks by processing them to create new products.

CTT employees in selected locations started to deposit used masks in specific containers, which when recycled and converted are polypropylene polymer plates. These, in addition to being resistant, allow the creation of new products, in this case Christmas tree decorations, already on sale in 50 CTT stores and in the online CTT store. Part of the proceeds will go to a social support institution
