The Koningshoeven BioMakery is a biological wastewater treatment system based on modular and functional reactor-based ecological engineering. The BioMakery was created based upon the principle of water-based urban circularity, where energy, food, and waste systems are built around a regenerative and sustainable water cycle. The BioMakery is powered by Metabolic Network Reactor (MNR) technology, which uses 2-3,000 different species of organisms ranging from bacteria to higher level organisms such as plants.
