Brussels, 8 July 2016-In the European Union, just over half of the waste we all generate is recycled, 13% is used for energy recovery but 35% is still disposed of, mostly in landfills. A report by Ecofys has clarified the role cement plants across the European Union can play and how they can be part of European and national waste management policies.
