Recommendations for the management of construction and demolition waste in treatment plants

Abstract

Construction and demolition waste consists approximately of one third waste generated in the European Union. The recycling of this stream waste will provide ecological and sustainable benefits. Recycled aggregates from construction and demolition waste are clearing a path into civil constructions, as substitutes for natural aggregates. The possible applications of recycled aggregates on infrastructure construction projects will depend on the quality of the recycled aggregates mainly. This will be determined by the nature and the origin of the construction and demolition waste, and the treatment system undergone. Hence, this work proposes recommendations for the handling of construction and demolition waste in treatment plants.

Sustainable Use and Management of Natural Resources in Construction: The Importance of Recycling

“…With regard to the original materials that compose C&D waste, one of the most important obstacles for high-value recycling is related to the original construction technique: if it requires wet operations, such as walls built of bricks and mortar, the selective demolition separating the basic materials increases costs [16] and is time-consuming. As a result, waste collected from nonselective demolition is 'dirty', greatly reducing or even zeroing their value for the production of second raw materials -unless they are subjected to adequate treatment processes with related costs -favoring their destination as low value material (usually aggregated) for construction works.…”

“…Their main results indicate a slight improvement in mechanical behaviour with the incorporation of EAFD, the reason why its use as SRM in conventional mortars would benefit the construction industry and would encourage the CE.

CDW consists approximately of one third waste generated in the European Union.…”
