How to make large amounts of biochar?

Date:July 8, 2025 16:00:45/ FAQ / Chat Online/ Leave message

The demand for high-quality biochar is surging, thanks to its key role in sustainable agriculture (soil improvement, carbon sequestration), renewable energy and advanced filtration technology. For companies ready to take advantage of this growth opportunity, efficient and sustainable production scale is essential.

Biochar is a solid product formed by heating biomass in the absence of oxygen through pyrolysis technology. This process not only retains the carbon element in the raw material, but also forms a porous structure, which gives biochar good adsorption properties and water holding capacity. Common raw materials that can be used to produce biochar include various organic wastes such as wood chips, crop straw, fruit shells, livestock and poultry manure, etc.

Traditional kiln production

Earth kilns and brick kilns are more traditional biochar production machine, suitable for small-scale production. This type of equipment has a low investment cost, but the production efficiency is not high, the thermal energy utilization rate during the production process is low, and the operator's experience requirements are high. Traditional methods often fail to meet the needs of large-scale continuous production of biochar, with low output, unstable quality, and huge impact on the environment.

Continuous biomass pyrolysis machine

DOING biochar carbonization reactor is designed for continuous operation and can quickly process large amounts of biomass. Automatic feeding of raw materials and continuous output of biochar enable true industrial-scale output to meet growing market demand. The biochar produced has a stable yield, usually exceeding 30%, which is much higher than traditional kilns or basic distiller. For users with higher daily output requirements, continuous pyrolysis machine is a more suitable choice.

To achieve efficient production of biochar, in addition to choosing the right machine, the optimization of the production process cannot be ignored:

Raw material pretreatment

Appropriate crushing and drying can improve pyrolysis efficiency and improve the quality of biochar. To help customers carbonize and produce more efficiently, DOING provides crushers and dryers to pretreat biomass raw materials. By crushing the biomass raw materials, it is ensured that they are evenly heated and efficiently carbonized, and after drying, the raw materials can be pyrolyzed more efficiently to obtain higher quality biochar.

Temperature control

Precise temperature control can produce biochar products that meet the requirements of specific uses. DOING continuous biochar reactor uses precise temperature control and pyrolysis process control-heating biomass in an oxygen-deficient environment. This optimized process maximizes the conversion of raw biomass into high-quality biochar.

Byproduct utilization

In addition to biochar, pyrolysis also produces syngas and wood vinegar. The combustible gas and liquid products produced can be recycled to reduce overall production costs. DOING biochar reactor system can efficiently capture and recycle these valuable byproducts. Through the heat recovery unit, the synthesis gas is recovered as fuel for the pyrolysis process or for drying the raw materials, thus significantly reducing the need for external energy. The wood vinegar can be collected for agricultural or industrial use.
