To process wood waste to organic fertilizer, two kinds of machines are necessary: wood chipper and hammer mill.
The raw material of organic fertilizer includes
☆ Agricultural and forestry waste(sawdust, branches, etc.),
☆ Animal and fowl excrement (chicken dung, cow dung, horse dung, rabbit dung, etc.),
☆ Industrial waste (vinasse, vinegar residue, cassava residue, sugar residue, furfural residue, etc.),
☆ Household waste (kitchen waste, etc.),
☆ City sludge (river muck, sewage sludge, etc.),
☆ Plant product (bamboo powder, bamboo charcoal, bamboo ash, straw charcoal, plant ash, etc.)
This project has a promising development as it can improve soil condition, improve soil hardening problem caused by chemical fertilizers, enhance soil capacity of water conservation , fertilizer conservation ,fertility supply, provide overall and durable nutrition to plant, increase and update soil organic matter and reduce environment pollution.
