Why rice husks for charcoal?

The farm produces a lot of rice hulls every year, so there's no need to worry about overuse

Rice husk carbon with high carbonization rate can be obtained with high quality

Environmentally friendly, charcoal production process does not produce any pollutants

The process

  Pyrogreen Biomass (Rice Husk) Gasifier Heating And Co Production Of Rice Husk Charcoal System includes: material feeding system, carbonization system(fine material), burner , waste heat boiler system, flue gas treatment system, etc. The working principle is that the biomass(such as rice husk, straws, bagasse, peanut shells and sunflower seed shells etc) have pyrolysis and gasification reactions with limited oxygen in the gasifier and generate combustible gas. The gas goes into the thermal-insulated furnace directly and then produce hot flue gas Which turns into steam or hot water after the waste heat boiler for civil and industrial use. Biochar/charcoal is used in our daily life and in industrial production and agriculture.

  Biochar is a carbon negative, charcoal based, soil amendment that can be designed to help reclaim and improve marginal soils by increasing soil water holding capacity and enhancing fertility, while also generating high-value renewable energy co-products during its production.
If deployed correctly, the biochar process is carbon negative: it removes net carbon from the atmosphere. When a green plant grows, it takes CO2 out of the air to build biomass. All of the carbon in the plant came from CO2 taken out of the air, and returns to the air when the plant dies and decomposes. When the biomass is instead pyrolyzed—heated in the absence of oxygen—it produces charcoal, which is called biochar when it is buried in the ground. Over 40% of the total carbon from the waste biomass is retained in biochar and sequestered in the soil for thousands of years, effectively removing that carbon from the atmosphere.




The carbon in 1 ton of biochar is equivalent to about 3 tons of CO2.
