2021-7-13  How to Recycle Concrete? When recycling old concrete from a demolition, the most common procedure is the following: STEP 1: Large pieces of concrete are first crushed with special industrial equipment that uses jaws and large impactors. STEP 2: Once the concrete is broken drown, it is screened to remove any dirt or contaminating particles. Additional processes and equipment such as water flotation, separators and magnets are used to remove other impurities from concrete.
