Under the background of "zero-waste city" construction, an environmental protection enterprise located in Hebei innovatively uses food processing waste (such as soybean meal, fish meal, and slaughter by-products) to produce amino acid organic compound fertilizer raw materials, processing more than 100,000 tons of waste annually, and realizing high-value utilization of resources.

It is reported that the company uses microbial fermentation technology to decompose the protein in the waste into small molecule amino acids, and adds humic acid and trace elements to make full-nutrition compound fertilizer. After testing, the heavy metal content of its products is far lower than the national standard, and the cost is 20% lower than similar products on the market.

Liu Bowen, the project leader, said: "This technology not only solves the problem of waste treatment, but also provides low-cost and high-quality fertilizers for organic agriculture. It is expected that the production capacity will expand to 300,000 tons next year." The industry believes that this model is expected to become a benchmark case for circular agriculture.
