Manure waste composting materials: The content of organic matter in the residue of the waste treatment industry is very high, reaching 40%, and the fertilizers such as nitrogen and phosphorus are abundant, and the average of O/N is about7%. However, substances containing poor dehydration rate after concentration and separation are generally prone to rot and deterioration, and are prone to malodor and parasites, and should be preserved and stored.
Okara as waste for composting production
The dry residue of bean dregs generally contains protein and lipids. It also contains many other components such as carbohydrate minerals and vitamins. It is rich in nutrients and is suitable for use as composting raw materials. The moisture content of wet bean dregs is about 80% and 90 ,, which is highly susceptible to spoilage. Due to the high nitrogen content of the bean dregs, carbon should be added when composting.
Beer dregs
The slag produced by the brewery fermentation is usually used as feed, but it can also be used as a good composting material.
Liquor
The slag contains a lot of organic matter, but the N, P, K content is low, the water content is about 90%, through the composting process.
The decomposition of microorganisms degrades organic matter, and can produce substances such as N, P, and K to improve the quality of organic fertilizer.
