Van Vliet Contrans collects the rockwool slabs and processes them into new raw materials. To do that, they first need to shred the slabs, and later on the material will have to rest for two months in order to dry.
Van Vliet now has a new drum installation to separate the rockwool from the organic and plastic materials. The remaining rockwool granulate is then suitable again for the production of stone bricks.
Van Vliet Contrans can process about 120.000m3 of rockwool slabs every year.
Here is a nice timelapse of the huge rockwool pile at Van Vliet:
