Abstract

Construction and demolition waste (CDW) are up 30% of waste sent to landfill in Europe. About 180 million tons per year are produced (about 480 kg per person per year). 28% is recycled, while the remaining 72% is disposed. In order to improve these waste management, noting the consequences resulting from landfilling, in Directive 2008/98/EC European Union requires the CDW recovery of at least 70%, by weight. In that way it’s possible to provide a future improvement of recycling techniques with a consequent high quality of the products and to expand the application field of recycled materials. This issue focuses attention on the CDW recycling problems: the different techniques and technologies for dismantling and processing are discussed, and the environmental impacts resulting from recycling activities are analyzed using a LCA (Life Cycle Assessment) approach. In particular, the aim of the study is to compare the environmental sustainability that might arise following the production of one tonne of aggregate stabilized derived from quarry natural material or from a CDW recycling process, in order to identify the best treatment process with less environmental impact and demonstrate the convenience to recycle.
