The non-polluting clean pulping technology in the field of straw pulp and paper makes the papermaking industry more energy-efficient and environmentally friendly in the coming years.
Straw energy straw can be converted into solid, liquid, and vapor fuels. The processing of straw into mechanism charcoal can be applied to some occasions such as metallurgy, chemical industry, construction, rural horticulture, animal husbandry, and domestic fuel. The straw gasification and conversion to alcohol fuel are new ways to use straw; corn Straw can also be used as a raw material for biomass power generation through extrusion.
