Professional waste disposal of waste of all types is one of the most important subjects of our time. Here, so-called secondary raw materials and final waste must basically be differentiated between. By secondary raw materials are meant all materials which are used for recycling processes after their throughput as basic materials for the manufacture of new products. The utilization of pure building rubble can be designated here as an example. By pure building rubble is meant bricks and concrete parts resulting from the demolition of buildings which must be disposed of as debris. This building rubble is transported in a recycling system and comminuted there in gigantic grinding equipment, in order to be then employed as ballast in road and rail construction. Final waste in turn must be either incinerated or finally stored in suitable refuse dumps.
