Broad Source of Sawdust Suitable for Sawdust Charcoal Machine

Sawdust, a versatile and widely available raw material, serves as a crucial component in the production of high-quality charcoal. Its broad sources include various industries where wood processing is a fundamental activity. Below are key sectors contributing to the ample supply of sawdust suitable for making charcoal.

Sawdust from Sawmill


A sawmill is where logs are processed into various forms of lumber. The wood-cutting process produces sawdust as a by-product.

  • Features: Sawdust from sawmills is abundant and easily available. Since sawmills typically process logs, the sawdust they produce usually contains fewer impurities.

Sawdust from Wood Panel

Wood Panel Manufacturer

Such factories produce products such as plywood and particleboard. A large amount of sawdust is generated during the molding process.

  • Features: The sawdust produced in the manufacture of wooden panels is usually fine and uniform. This contributes to an efficient pyrolysis process and high-quality charcoal output.

Sawdust from Furniture

Furniture Manufacturer

Furniture manufacturers generate sawdust by cutting, shaping and sanding wood when making wooden products.

  • Features: The sawdust generated during the furniture manufacturing process is often a mixture of hardwood and softwood, providing a variety of raw materials for charcoal production.


  • The particle size of sawdust entering the wood charcoal making machine should be less than 20mm. More uniform particle size helps improve reaction efficiency.
  • The higher moisture content of sawdust may result in incomplete combustion. It is usually necessary to ensure that the moisture content of the sawdust is less than 15%.

Versatile Applications: Sawdust Vs. Sawdust Charcoal

Sawdust and sawdust charcoal are versatile byproducts with diverse applications, each offering unique advantages and environmental considerations. Below, we explore their applications in various fields and compare their performance.

Wood Waste to Sawdust Biochar: Circular Carbon Footprint

Beston biochar equipment can convert sawdust into biochar, a material with extremely strong carbon sequestration capabilities. From the generation of sawdust to the carbon sequestration application of sawdust biochar, this process realizes the cycle of carbon footprint.

Circular Carbon Footprint

Circulation Process Of Carbon Element

Forest Photosynthesis:
Forest photosynthesis is one of the important carbon cycle processes in nature. Through this process, plants use sunlight’s energy to convert atmospheric carbon dioxide into organic carbon. This helps maintain carbon dioxide levels in the atmosphere.
Wood Harvesting&Processing:
Timber harvesting and processing are common application scenarios of forest resources. But it is also accompanied by the generation of wood waste. Carbon is present as waste biomass in sawdust and other unused parts of wood.
In conditions with little or no oxygen, sawdust is converted into sawdust biochar through in sawdust charcoal making machine. This process not only produces biochar with a high carbon content but also releases biogas that can be used for energy production.
Carbon Sequestration:
Adding biochar to forest soil is a carbon sequestration strategy. Biochar has a longer stability and therefore slows down the rate of organic carbon decomposition. Thus, biochar helps sequester carbon and slow the increase of carbon dioxide in the atmosphere.

Positive Effects Of Making Biochar From Sawdust

Promote Forest Growth

Promote Forest Growth

Adding sawdust biochar to soil improves soil structure and nutrient content. Therefore, this improves plant growth suitability. In addition, biochar can also help increase soil water retention and reduce soil erosion. Thus, this creates an environment more conducive to plant root development and growth. Enhancing the carbon dioxide absorption capacity of vegetation in the forest effectively assists the carbon fixation process. This helps maintain the carbon balance in the atmosphere.

Carbon Emissions Offset

Carbon Emissions Offset

During the harvesting and processing of wood, there is usually a certain amount of carbon emissions associated with it. This comes from aspects such as fuel and product transportation for processing machines. However, by converting sawdust into biochar and adding it to the soil, permanent carbon fixation can be achieved. This means that through the use of biochar, the carbon emissions produced during wood harvesting can be effectively offset, thereby reducing the negative impact on the climate.

How to Make High-quality Charcoal from Sawdust?

Pretreatment of Sawdust

Continuous sawdust charcoal making machine requires a sawdust particle size of less than 20mm(preferably 5-8mm) and a moisture content of less than 15%. We provide a crusher/dryer. The sawdust meeting the feeding requirements enters the main combustion furnace through a large-angle belt conveyor.


Pyrolysis of Sawdust

During the entire pyrolysis process, the reaction temperature can reach 450°C. The reaction environment is micro-oxygen negative pressure. The sawdust undergoes a thermal desorption process to remove excess volatile matter. Subsequently, the carbon in the sawdust begins to remain and gradually forms a solid carbonaceous material: charcoal.


Collection of Sawdust Charcoal

The sawdust charcoal coming out of the reactor has a higher temperature. After entering the discharging system, the heat of the sawdust charcoal is taken away by the water-cooled slag discharging spiral. Eventually, the temperature of the collected finished sawdust charcoal dropped below 45℃. In addition, we also provide integrated molding production lines to solve the problem of how to make charcoal briquettes from sawdust.


Treatment of Flue Gas

After the biogas undergoes dust removal and condensation treatment, the combustible gas enters the combustion system to provide a heat source for the equipment. Then, the dust and sulfur in the hot flue gas are removed from the spray tower/demist tower to ensure that the final flue gas meets EU emission standards.
