ABSTRACT
The volume of the waste generated is constantly growing due to the increase of the development rate, but also due to change of consumer patterns. After cement production, urban solid waste represents the largest mass of solids produced worldwide. Due to their significant volumes, the cases of reverse logistics for waste electrical and electronic equipment (WEEE) and construction and demolition waste are further detailed. The European Union has introduced extensive environmental legislation for WEEEs, which is based on the responsibility of producers who are required to finance their collection, treatment, recovery and environmentally sound disposal. The environmental hazard of the materials depends on their toxicity, as well as on the quantities released during WEEE management. Reuse is the process during which a product is used from the beginning in the same or similar purpose for which it was originally manufactured, using its original shape.
