Date:2023-02-27


On Feb. 23, the finalof the National Disruptive Technology Innovation Competitionwas held in Hangzhou City, Zhejiang Province. DHU Cai Dongqing's team fromthe College of Environmental Science and Engineering won the Excellence Award for their project, "Development and Application of One-Hour Nano-Decomposition Technology for Organic Solid Waste."

With 3 years of research and experiments, Cai Dongqing's team developed the original one-hour nano-decomposition agent and proposed an innovative theory of  molecular shearing effect and rapid decomposition. Their technology enables organic solid waste such as livestock manure and kitchen waste to be decomposed into highly active organic fertilizer within one hour.


Compared with traditional composting, this technology is disruptive in that: 1) the decomposition cycle is reduced from 30 days to one hour (720 times more efficient); 2) it is almost 100% harmless and effective against bacteria, hormones, antibiotics, and heavy metals;3) the fertilization efficiency is significantly higher than that of traditional organic fertilizers.It can also save 70% ofspace and labor, and reduce carbon by more than 30%. This technology provides a disruptive solution to China’s rural non-point source pollution caused by the farming industry. It has been granted four invention patents, licensed for use to three companies and applied to more than 100,000-mu(roughly 24750 acre)land; a 150,000-ton organic fertilizer production line has also been built. The technology has won several prestigious awards and was selected as a finalist in the 2022Shanghai Global Innovation and Entrepreneurship Competition.
