Weltec Biopower's First Kumac Plant in Germany Goes Live

In March 2024, Agrar GmbH Reichenbach commissioned its Kumac digestate processing system from WELTEC BIOPOWER.  This is the first Kumac plant to go live in Germany, in addition to the 16 that have been built worldwide to date. The agricultural company based in the Vogtland region of Saxony, Germany, specializes in dairy farming and the cultivation of feed crops. In addition to the dairy farm with 1,400 cows and breeding cattle, the farmers have been operating a biogas plant with an electrical output of 845 kW since 2006. The facilities generate up to 72,000 t of liquid manure and digestate per year.

Every day, the biogas plant feeds 12,000 kWh of electricity into the public grid. In addition, the plant supplies up to 500 kW of heat to small consumers and to the site of the former Paracelsus Clinic in Reichenbach via a heating network.

The plant‘s main business consists of the delivery of biogas via a 3.2-km raw biogas pipeline to the heating plant of Stadtwerke Reichenbach for the base load supply of flats and social facilities. The amount of electricity generated each year corresponds to the annual consumption of around 6,000 private households.

 High-Quality Fertilizer for Plant Cultivation

"In Reichenbach, the output of the Kumac process consists of around 25 percent solid and 20 percent liquid farm manure and 55 percent dischargeable water. The resulting solid matter and the nutrient concentrate are applied as organic, high-quality fertilizer to our own crops. In this way, long transport routes are avoided,“ explains Lars Bittermann, Managing Director of Agrar Reichenbach GmbH.

"This closes an efficient material flow cycle, and the individual areas of our portfolio interlock perfectly. From the cultivation of feed crops to dairy farming to the utilization of the liquid manure in the biogas plant and the processing of digestate into fertilizer and water, all components have their place."

Support from the European Agricultural Fund

The scalable modular system can be used from an amount of 70,000 t of liquid manure or digestate a year. Should the processing needs increase, several Kumac lines can easily be combined.

"The processing here is almost fully automated, which also minimizes the amount of personnel required," says Managing Director Lars Bittermann.

"By the way: Operators who decide to set up a system can receive funding from the European Agricultural Fund for Rural Development," adds Nico Sudbrink, the responsible process engineer at Weltec Biopower.
