In the wide wheat cultivation areas, in order to deal with the wheat straw quickly, it basically goes through the incineration treatment, which not only pollutes natural air, but also wastes the valuable resources.
Biomass pellet mill is the equipment used to suppress crude fiber, sawdust, straw particles and other materials, which is suitable for the twigs, straw, bamboo and other materials.
Bagasse is the main by-product of cane sugar. Bagasse is rich in fiber and less in ash, which is a kind of clean, high-quality and sustainable biomass energy.
