Europe: What to do with all that stonewool substrate?

For many years now, the Dutch company Milieu Express has been recycling stonewool from growers in Oostland and the surrounding areas. To make the material suitable for reuse, the rockwool slabs and plastic are expertly separated from the foliage. The rockwool is shredded, sifted and then separated into three fractions: clean rockwool, foil scraps and waste.

Crop rotation is a special period for Milieu Express.. "A nice, busy period loading a lot of rockwool." And it shows: there are huge amounts coming out of the European greenhouses.

Brickworks

Milieu Express delivers the clean wool to brick factories on call. These add the material to a special clay. From this mixture the industry manufacturers new brick material for interior walls. The foil scraps are sent to plastic recycling. This fraction is the raw material for new plastic products.

The residue consists largely of green waste. The green material is the ideal basis for compost. The company Van Vliet Recycling processes this fraction into compost. To act quickly during crop rotation extra large container trucks - capacity 40 cubic meters - are available, equipped with grab cranes.

In this way 99% of the collected rockwool is successfully recycled. Only 1% is incinerated or landfilled. And how does that goes? This can be seen in the video below:
