Straw charcoal machine converts agricultural waste into up to 6,000 tons of biochar per year. The biochar produced meets EBC standards and is perfect for soil enhancement and carbon sequestration. This solution supports sustainable agriculture, circular economy, and climate change mitigation. If you’re facing excess straw disposal challenges, please contact us for a recycling solution.
Annually, billions of tons of agricultural straw waste are generated worldwide, with corn straw, rice straw, and sugarcane bagasse being the most prevalent. Traditional disposal methods have limitations. The straw charcoal making machine (bichar making machine) offers a sustainable alternative, benefiting both the environment and economy.

Pipe insulation prevents the condensation of tar and wood vinegar, avoiding blockages. The nitrogen purging system prevents the accumulation of high-temperature dust and pipe blockages.
Key Effect:
This achieves a staged and complete carbonization effect. The inner cylinder achieves the drying and partial carbonization of the straw. The outer cylinder further ensures complete carbonization.
Key Effect:
A controlled high-temperature environment maximizes fixed carbon retention while minimizing ash and impurities. This ensures high-quality biochar suitable for advanced applications.
Key Effect:
It enhances combustion efficiency, reduces incomplete fuel combustion, and indirectly lowers greenhouse gas emissions, better meeting emission standards.
Key Effect:
The high-end exhaust gas treatment system cools, removes particulate matter, desulfurizes, denitrifies, and adsorbs harmful substances from exhaust gases.
Key Effect:
It ensures more complete combustion of syngas and fuels, reaching sufficient combustion temperature and residence time as the pyrolysis reaction requires.
Key Effect:
Under high temperatures (380-450℃), agricultural straws decompose. At 150 ℃, some of the raw materials start to decompose into CO, CO2, etc. At 350 ℃, charcoal appears continuously.
Straw biochar is water-cooled via heat exchange and discharged at a temperature below 45 °C.
Once the residual heat in the waste gas is recovered, the remaining exhaust requires proper treatment. A dedusting system (cyclone dust remover, spray dust collector, etc.) will remove harmful components such as sulfur from it.
Representatives: Wheat straw, corn stalks, rice straw, sorghum stalks, etc.
Representatives: Cotton stalks, flax stalks, jute stalks, etc.
Representatives: Soybean straw, peanut vines, broad bean stalks
Sell straw biochar to large farms and environmental organizations for soil remediation and fertility enhancement. It improves soil structure, retains nutrients, and promotes microbial activity.
Partner with carbon offset programs or organizations. As a stable form of carbon, straw biochar qualifies for carbon removal and supports long-term carbon sequestration strategies.
Supply straw biochar to construction material manufacturers. Added to concrete and composites, it cuts carbon emissions by 30% and improves thermal insulation and structural strength.
Sell straw charcoal briquettes to the catering industry, especially the BBQ market.
Sell straw charcoal to energy-intensive industries aiming to reduce fossil fuel dependence.
Provide straw charcoal to metal smelting plants as a renewable metallurgical reducing agent. It replaces coal-based products in the smelting process.
Offer biochar to feed manufacturers and livestock farms. Used as a feed additive, it promotes animal gut health, reduces methane emissions, and aligns with the goals of sustainable livestock management.
Crop residues like wheat, rice, and corn straw are converted into biochar through pyrolysis using straw charcoal machine. This clean process prevents open burning, reduces pollution, and locks in carbon that would otherwise enter the atmosphere.
The biochar produced meets EBC-Agro standards and is ideal for farmland application. When added to soil, it enhances aeration, boosts water retention, and binds nutrients. This creates a better environment for plant growth.
As biochar improves soil structure and nutrient cycling, crops grow stronger and require fewer chemical inputs. It’s a smart investment in productivity and sustainability — all while cutting emissions and closing the loop.
