Safe Innovative Processing Of Carcinogenic Waste Thanks To MAP

Innovative process developed by Germain engineering company and University of Geissen

MAP® Continuous Ploughshare Mixer in Wool.rec waste processing plant in Germany

The Wool.rec company, based on the edge of the High-Taunus natural park, in Braunfels-Tiefenbach, in central Germany, has focused its activities on the environmental-friendly disposal of waste glass and rock wool which are extremely damaging to health. In fact, both materials are suspected to cause cancer. According to German federal law, such materials require certified disposal in hazardous waste depots which generates extremely high costs for the customer.

In cooperation with the University of Geissen, Wool.rec has developed a method by which crushed mineral wool is processed together with clay, water and other secret ingredients into granules. These granules are further processed into bricks adding particular stability and durability to the product. Burnt in a kiln, the glass fibres form a stable compound with the clay which is unlimited in time.

For the production of the granules, Wool.rec decided on a Continuous Ploughshare Mixer by MAP®. Due to its mode of operation the WAH-type mixer offers a high degree of homogeneity of the mixture, thus making such a process possible. Reliable two-shift operation is guaranteed thanks to a fluid coupling for soft motor start, as well as the presence of high-speed choppers fitted on the mixer drum.

The process has won Wool.rec awards on more than one occasion and approval for new projects in other German states
