The CEWASTE project aimed at contributing to an improved recovery of valuable and critical raw materials (CRMs) from key types of waste through traceable and sustainable treatment processes in the entire supply chain of secondary raw materials. In this context, the project developed, validated and launched a voluntary certification scheme for collection, transport and treatment facilities of waste electrical and electronic equipment, batteries and end-of-life vehicles. The scheme was piloted at companies in Belgium, Italy, Portugal, Spain and Switzerland as well as Colombia, Rwanda and Turkey.
