Take the quality, technology, intelligent ecological toilet as an example. It relies on the cross-line application of nanotechnology, biotechnology, sensor technology, new material technology, AI technology and other patents to build an waterless ecological treatment system, separating feces from the source and treating them separately. Feces can be decomposed into organic solid fertilizers by microbial degradation technology, and urokinase and ulinastatin are extracted from urine by its patented technology, and the rest are converted into organic liquid fertilizers, which are then applied to organic fruits and vegetables.
