Cement recycling is an increasingly common method to reuse debris resulting from the demolition or conditioning of structures made of this material. Cement used to be transported to "Landfill (garbage)" landfills for disposal, but recycling it has a number of benefits that have made it a more attractive option in this era of environmental awareness, environmental laws, and the desire to keep construction costs as low as possible.[1]​.

The cement aggregate "Arid (mining)") collected after demolition is introduced into a grinder. The grinding units accept only uncontaminated pieces of cement, that is, they must be free of garbage, wood, paper, and other similar materials. Metals such as those used in forging are acceptable, since they can be eliminated thanks to electromagnets and other separation systems, after which they are melted for recycling in other facilities. The remnants of the cement blocks are arranged by size. Larger pieces can be returned to the machine. After grinding, the particles are filtered by several different methods, including hand screening and flotation.[2]​.

On-site grinding using transportable grinding machinery reduces construction cost and pollution generated when comparing material to and from a quarry. There are large portable road machines that can grind cement and asphalt at a rate of up to 600 tons per hour. These systems typically consist of a debris chopper, side discharge conveyor, filter unit, and a conveyor belt to return larger chunks to the chopper. Other smaller machines are also available, which can handle up to 150 tonnes in an hour and can be installed in smaller areas. With the advantage of other auxiliary machines, such as excavators, the trend of on-site recycling in small volumes is growing rapidly. These sets allow the recycling of volumes less than 100 tons per hour.[3]​.

Smaller pieces of cement are used as gravel for new construction projects. The base gravel is placed as the lowest layer of roads, followed by the pouring of more cement or asphalt.

Larger pieces of cement, such as riprap, can be used for erosion control.

With adequate quality control at the milling facility, certain quality, aesthetically appealing materials can be supplied as a substitute for stucco and padding.

Gabions can be filled with ground concrete and stacked to create economical retaining walls. Stacked gabions are also used to increase the privacy of a location, instead of using a fence.
