Another component of the new company portfolio is the 0/8mm turf substrate, a mixture of topsoil, lava, and appropriate compost components, which can be used to lay rolled turf or to sow lawns. Product Manager Ralf Beissel, says, "We pass this material on to garden- and landscape builders unfertilized. Pumice is often an integral part of the substrate or part of the topsoil as we only process pumice-containing soils from the region. Lawn substrate requires 35% water storage, and the compost content is correspondingly high. At our quarry in Ettringen, we use our own laboratory to independently test grading curves, water storage, and all-important components of the substrate for reliability."
Germany's largest Metso Outotec mobile plant operator
Bierbrauer & Sohn GmbH has maintained close business relations with Metso Outotec dealer Fischer-Jung Aufbereitungstechnik GmbH, from Krefeld, for nine years. The family business and its sister company Terratec-Basalt GmbH now operate a total of 24 Metso Outotec mobile plants, making them the largest customer of the Finnish manufacturer in Germany. "I can only praise the cooperation with Fischer-Jung Aufbereitungstechnik, our direct contact, in the highest terms – on the one hand, on the service side, the training of our personnel, and on the other hand, we are always supplied with the necessary spare and wear parts in time. Every year, we stock up with crushing jaws, impact bars, the necessary screws, crushing shells, crushing cones and screen linings. In the overall package, we benefit from more favorable purchase conditions when we plan a year in advance. Since we are also permanently required in the area of contract crushing and screening, the stocking of spare and wear parts is vital for us," says Karl-Werner Bierbrauer.
