With the increasing awareness of environmental protection and the emphasis on resource recycling, kitchen waste is gradually becoming an emerging raw material for organic fertilizer granulation, demonstrating enormous potential.
Leftover food is the main component of kitchen waste, which contains abundant organic substances such as carbohydrates, proteins, and fats. These substances are easily decomposed and utilized by microorganisms under appropriate conditions. After classification, collection, and preprocessing, leftover food can enter the fermentation system. Under the action of microorganisms, they are decomposed into small organic molecules, releasing nutrients such as nitrogen, phosphorus, and potassium. Mixing the fermented product with other auxiliary materials and processing it through an organic fertilizer granulator can produce nutrient rich organic fertilizers.
The fruit peel is also a high-quality organic fertilizer raw material. Apple peels, banana peels, orange peels, etc. are rich in various vitamins, minerals, and bioactive substances. During the fermentation process, these substances will gradually decompose and blend into fertilizers, providing unique nutrients for crops. For example, banana peels contain high levels of potassium, and processed organic fertilizers can effectively increase the potassium content in the soil and enhance the stress resistance of crops. Using an organic fertilizer granulator to turn fermented fruit peels into granules facilitates fertilization operations and better preserves nutrients.
Bones can also be used for organic fertilizer granulation after processing. Bones contain a large amount of minerals such as calcium and phosphorus, which can become important sources of nutrients in fertilizers after being crushed and fermented. Especially for some crops that require calcium and phosphorus supplementation, the use of organic fertilizers containing bone components has a significant effect. Processing it into granular fertilizer through an organic fertilizer granulator can not only improve the utilization rate of fertilizer, but also reduce odors and facilitate storage and transportation.
Although waste oil cannot be directly used as organic fertilizer raw materials, after special treatment, it can be mixed with other organic materials to participate in the fermentation process. Waste oil is decomposed by microorganisms to produce fatty acids and other substances, which help improve the physical properties of fertilizers, increase their viscosity, and make the granulation process smoother.
Kitchen waste, as an emerging raw material for organic fertilizer granulation, not only solves the problem of waste disposal, but also provides new fertilizer resources for agricultural production. By proper treatment and processing with organic fertilizer granulators, kitchen waste can be turned into treasure, making positive contributions to ecological agriculture and sustainable development.
