Construction waste is made up of a variety of materials, including mortar, bricks and cement- and lime-based materials, which gives it its characteristic reddish colour. As an important component of the construction industry, building rubble has considerable recycling potential. However, in its unprocessed state, construction waste can hardly be reused, if at all.

In Europe, it is forbidden to reuse contaminated construction waste without processing it, as the chemical contaminants can jeopardise the groundwater. Contaminated rubble must be separated from harmful substances and disposed of properly at recycling centres. Otherwise, the material must be disposed of in a landfill.

Reprocessing and recycling construction waste

Large, unmixed chunks of rubble have high potential for reuse, provided they are properly processed to remove all impurities and contaminants. To produce reusable rubble, the fine materials with a grain size of 0-20 mm, which usually contain chemical impurities, must be screened and disposed of in landfill sites. The remaining construction waste can be processed by the impact crusher and separated from additional impurities (plastic, wood insulation, etc.) using an air separator. The recycled rubble can then be used, for example, to backfill the site or for hall substructures.

Tips for a higher quality end product when crushing construction waste

Ideally, buildings are selectively dismantled directly on site during demolition. Dadurch können die meisten Fremdstoffe aussortiert und eine Vermischung mit den mineralischen Materialien vermieden werden. This makes the subsequent recycling process considerably easier and ensures a high-quality end product.

Difference: Construction waste & mixed construction waste

Not to be confused with construction waste is non-mineral mixed construction waste, which contains additional materials such as glass, wood and plastic and must be disposed of separately. Generally, mixed construction waste is more expensive to dispose of than construction waste and must be disposed of separately. An air separator is used in the next step to remove further impurities. At RM, this is integrated directly into the crusher and reduces the recycling process by one step.

FAQ’s

What is construction waste made of?
Construction waste consists of mortar, bricks and cement- and lime-bound materials. Mixed construction waste is often also referred to as building rubble, but this also contains non-mineral materials such as wood, plastic and glass.

Can I reuse construction waste?
Yes, but only if the material is unmixed and does not contain any impurities. Construction waste that has already been used is often already chemically contaminated and must not be reused as it can poison the groundwater and cause damage to health.

How can I reuse construction waste?
0-20 mm material is sieved off. This contains chemical impurities and is unusable. Once the clean material has been separated from the contaminated material, it can be crushed into the desired grain size using an RM crusher.

What colour is construction waste?
Building rubble consists partly of bricks and therefore has a reddish colour.

Does construction waste contain wood?
No, construction waste consists of mineral components such as bricks and lime-bound materials. Mixed construction waste, however, consists mainly of non-mineral components such as wood, glass and plastic and is often confused with construction waste. Please note – mixed construction waste must be disposed of separately.
