The biggest difference between kitchen waste and kitchen waste is the source and composition.

First of all, kitchen waste mainly comes from restaurants, canteens and other catering places, including food residues generated during dining, wastes generated during food processing and discarded cooking oil. These wastes usually contain high oil and salt, which are easy to deteriorate and produce odor and germs.

The kitchen waste mainly comes from the family kitchen, including leftovers, peels, vegetable stems and leaves, etc. These wastes usually contain more water and organic matter and are relatively perishable. Due to the different sources and components, there are also differences in the treatment methods between kitchen waste and kitchen waste. Kitchen waste usually needs professional oil-water separation, harmless treatment and other processes to avoid environmental pollution, while kitchen waste can be recycled by composting and other means.

Treatment method of kitchen waste

1. Physical separation treatment: The kitchen waste is broken and separated by physical separation equipment, such as crusher and sorter, so as to separate out impurities and obtain relatively pure organic matter.

2. biological treatment: the organic matter in kitchen waste is converted into fertilizer or biogas by the fermentation of microorganisms. This method can not only reduce the amount of garbage, but also realize resource utilization.

3. heat treatment: the organic matter in the kitchen waste is oxidized or pyrolyzed by technologies such as high-temperature incineration or pyrolysis to obtain substances such as heat energy or combustible gas. This method has high treatment efficiency, but the equipment and operation costs are high.
