[0002] Organic solid waste refers to the waste containing a large amount of organic matter and in the form of solid. It is mainly divided into three categories: first, household garbage, such as kitchen waste, waste food, paper and cloth, etc. These will seriously pollute the environment if not properly handled. Secondly, industrial, by-products, waste and wastewater from the production process, containing organic solvents and heavy metals, posing a threat to the environment and human body. Finally, agricultural, such as livestock manure, straw, etc. If not properly handled, it will also pollute the soil and water. For these organic solid waste, we can take composting, biological decomposition and incineration and other treatment methods to convert it into harmless or useful resources, thereby effectively protecting the environment and human health.
