The manufacture of recycled aggregates is an industrial process making it possible to turn the stone fraction of construction and demolition waste into a finished product – recycled aggregates – suitable for use on site or in another industrial process. Modern processing facilities can work well either in the open air or in closed industrial units. The latter include all technological advances for controlling waste and emissions into the atmosphere, particularly dust and noise. Each facility makes products depending on the waste it accepts, the machinery it uses and the needs of the area. As well as the fixed facilities, there are mobile ones that move around the region, providing service where needed.
The recycled aggregate manufacturing process includes a series of operations. The most important of these are cleaning, crushing, screening and grinding. The recycled aggregates made are analysed and systematically classified by approved laboratories to ensure their quality.
