remexit® is produced by mechanical treatment of construction and demolition rubble in one of our numerous recycling plants. The resulting recycling materials thus fall under the term of industrially manufactured substitute construction materials. Processing generally comprises the steps of crushing, screening, sorting out impurities and separating metals, in this case iron, using magnetic separators. In order to achieve good recycling qualities from the CDM waste, individual steps are carried out several times on different grain sizes. The metals recovered during the process (e.g. reinforcing steel) are recycled.
The resulting mineral fraction is combined into different sieve lines and classes depending on their intended use. In road construction, aggregates 0/32 and 0/45 are mainly used as a substitute for base layers.
The construction waste can also be processed on site by means of a mobile plant, enabling local recycling. However, most of the CDM waste is processed in our high-performance stationary recycling plants and subsequently marketed as remexit® recycled aggregate.
