This week is the European Week for Waste Reduction (EWWR), the biggest campaign to raise awareness about waste prevention in Europe. Driven by local and regional public authorities, we bring together all sorts of other actors — citizens, schools, businesses, NGOs, associations — who organise activities to raise awareness about waste reduction.What makes it special are the efforts and passion invested by the thousands and thousands of volunteers who spread the word about sustainable consumption and circular economy in their communities.
