The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed. After this step, the concrete is separated out by size.

Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate. Additional processes and equipment, such as water flotation, separators, and magnets, may also be used to remove specific

Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn’t knocked down as a whole, but the materials are taken down selectively.
