With more than 30 years of engineering practice, the DRANCO has proven to be an efficient anaerobic digestion process for the treatment of high solid concentration organic waste such as kitchen waste.

PURAC is an officially authorized partner supplier of DRANCO^® technology in China. With its unique feeding and mixing method, DRANCO^® is one of the typical representatives of dry fermentation processes in the world, and has already more than 30 application cases in Europe and Asia by the end of 2023, mainly for the treatment of kitchen waste, garden waste, straw, livestock manure, and industrial organic solid waste. Compared with the wet anaerobic process, this technology can adapt to a larger feed solids content range (20%~55%), and has lower pretreatment requirements for incoming materials (to reach the particle size ≤50mm, and the organic content≥70%).
