A few days ago, the China High-tech Industrialization Research Association presided over the scientific and technological achievements evaluation meeting
of "using gelatin production residue to prepare bio-organic fertilizer" in Beijing.
Experts believe that the technical and technological level of this achievement is advanced, and the products meet the relevant standards of the country and the industry, reaching the leading level
in China.
The residue generated during gelatin production contains organic matter, bacteria, pathogens, inorganic particles, colloids, heavy metals, etc
.
With the traditional stacking treatment method, it is easy to cause secondary pollution to the surrounding environment, and the quantity is huge, accumulating over time, and occupying a large amount of ecological space
.
After long-term scientific research, Heilongjiang Yihui Agricultural Technology Co.
, Ltd.
has successfully developed "bio-organic fertilizer preparation technology using gelatin production residue"
based on patented technology with independent intellectual property rights.
The result uses gelatin production residues, straw and animal manure after harmless treatment, according to the required proportion of closed fermentation process, automatically measured and compounded into multi-element organic fertilizer, and then measured and mixed with Chinese herbal medicines in biological fermentation, and uses some patented process technologies to produce bio-organic fertilizer
.
By adding complex functional bacteria, the utilization rate
of bio-organic fertilizer and double-effect multi-element fertilizer can be effectively improved.
It is reported that after the project is fully completed, the daily processing of gelatin residue is 2,000 tons, and the annual treatment capacity will reach 200,000 tons
.
Experts suggest that the research on product adaptability should be strengthened for this achievement, and further increase promotion efforts to meet market demand
