This category is mainly a mixture of construction debris, excavated earth, plastics films and containers, iron parts and others. In Sutco waste treatment plants the valuable raw materials contained in it are separated from non-recyclable materials.
Presorted by a mobile excavator, the waste is separated to form different grain sizes by an especially robust multi-stage trommel screen and is manually separated via the especially powerful conveying equipment by machines (e.g. metal separator, windshifting equipment etc.).
The recyclable fraction such as stones, sand, earth etc. are then recycled.
