What are the types of biomass energy sources

Forestry resources, agricultural resources, sewage wastewater, solid waste, livestock and poultry manure, biogas and so on.

Forestry resources

Forestry biomass resources refer to the biomass energy provided by forest growth and forestry production processes, including charcoal forests, scattered wood, residual twigs, leaves, and wood chips in forest nurseries and inter-felling operations; branches, sawdust, wood chips, tips, board skins, and cut-offs in the process of timber harvesting and processing; and the waste from forestry by-products such as fruit shells and kernels. .

Agricultural resources

Agricultural biomass energy resources refer to agricultural crops (including energy crops); waste from the agricultural production process, such as crop stalks (corn stalks, sorghum stalks, wheat stalks, rice straws, soybean stalks, and cotton stalks, etc.) that remain in the farmland when crops are harvested; and waste from the agro-processing industry, such as rice husks left over from the agricultural production process.

Sewage Wastewater

Life wastewater mainly consists of a variety of drainage water from urban residential, commercial and service industries, such as cooling water, bathing drainage, washing drainage, laundry drainage, kitchen drainage, fecal wastewater and so on.

Solid Waste

Municipal solid waste is mainly composed of urban residents living garbage, commercial and service industry garbage and a small amount of construction industry garbage and other solid waste. Its composition is complex and is influenced by factors such as the average living standard of local residents, energy consumption structure, town construction, natural conditions, traditional habits and seasonal changes.

Livestock and poultry manure

Livestock and poultry manure is a general term for livestock and poultry excreta, which is a transformed form of other forms of biomass (mainly food, crop residue and pasture, etc.), including feces, urine and its mixture with bedding grass discharged by livestock and poultry.
