Weltec Biopower will mainly present its plant concepts for the energetic utilization of organic waste and agricultural leftovers. The consistent anaerobic digestion of leftovers requires a combination of individual planning and reliable components. Weltec’s technologies are highly suitable for processing various types of waste; the range of technologies comprises the use of stainless steel as a construction material, substrate shredding units, hygienization solutions and compatible control technology.
The booth will also showcase the liquid manure and digestate processing system Kumac. With this trend-setting system, Weltec offers a technically mature procedure for the efficient reduction of the slurry and digestate volume. Several Kumac systems have been operating in Belgium and the Netherlands for 11 years.
In late summer 2019, the first system of this type in Germany will go live in Saxony. The operation yields 70,000t of cattle slurry a year, which will first be utilized energetically in a biogas plant and then refined to water, liquid fertilizer and solid matter. The extraction of water will reduce the digestate volume by more than 50 percent. This concentration of the nutrients will reduce the amount of slurry transports and facilitate the spreading of the fertilizer on the fields.
