Environmental technology

We are driving the energy transition - actively, sustainably and with innovative products. Our versatile extruder is THE revolution in the biogas sector. It makes a major contribution to the reduction of peat in landscaping and horticulture and thus sets standards for the protection of habitats, valuable resources and, last but not least, the climate.

Pioneering extruder technology

With our extruder, we have developed the pioneering technology for defibering organic materials. Equipped with two counter-rotating screws that are precisely tailored to your specific area of application, the materials used and your process, it defibrates and breaks down biological source materials right down to the cell structure.

Modular design

The extruder is manufactured as standard in various series with connected loads from 22 kW to 240 kW. The system has a modular design, is low-wear and extremely easy to maintain. Any service work is carried out quickly and easily by trained personnel.
