EFFICIENT SLURRY AND DIGESTATE PROCESSING WITH „KUMAC“ FROM WELTEC easy_international December 9, 2016 NEWS German biogas specialist WELTEC BIOPOWER now offers a proven solution for the processing of slurry and digestate for livestock owners and biogas plant operators. The fully automated processing system „Kumac“ reduces the liquid manure and digestate volume by 50 percent. In a four-stage procedure, clear water, liquid fertiliser concentrate and valuable solid matter are extracted from the source material. Regions characterised by agriculture are faced with a high accumulation of slurry and digestate, while the areas suitable for spreading the nutrients are limited. In the future, restrictive laws will impose even stricter regulations for handling the nutrient surplus. Against this background, operators are finding it more and more costly to store and dispose of liquid manure and digestate. WELTEC BIOPOWER‘s Kumac processing system represents a sustainable, economic solution for reducing the quantity, thereby improving the transportability and volume of the nutrient surplus.
