Sawdust to Charcoal Machine

Different Sawdust Recycling Solutions Comparison

Millions of tons of sawdust waste are created each year from the 15 billion cut trees. They pose threats to the environment and human health. The common sawdust recycling solutions include accumulation, burning, composting, etc. But compared to the sawdust to charcoal solution, they all have some limitations.

Burning Directly

Sawdust Burning


Dust hazard: The combustion of sawdust produces fine particulate matter (dust), adversely affecting air quality and human health.
Greenhouse gas emissions: The burning wood of sawdust releases a certain amount of CO2 and other greenhouse gases.


Sawdust Accumulation


Incomplete disposal: Piled sawdust remains, not gone.
Fire hazard: Sawdust has small particle size and high flammability. Accumulated sawdust can easily catch fire hazards and dust explosions.
Groundwater pollution: The substances such as lignin and fatty acids in sawdust may release harmful leachate into the surrounding water system.


Sawdust Composting


Slow decomposition: Fine sawdust easily compacts, resulting in reduced airflow, slowed decomposition, and consequently limited processing capacity.
Harmful gas emissions: The microbial decomposition process of composting may produce pungent odors such as ammonia and hydrogen sulfide, as well as climate-damaging methane gas.

Animal Bedding

Sawdust as Animal Bedding


Incomplete disposal: The sawdust remains, not disappeared. Moreover, sawdust contaminated with animal urine and feces becomes even more challenging to handle.
Limited processing capacity: Not all kinds of sawdust are appropriate (eg. black walnut is dangerous for some animals).

Manufacturing Particleboard

Sawdust to Manufacture Particleboard


Energy and chemical consumption: The processing and bonding of sawdust-based particleboard typically requires significant energy and chemical inputs like adhesive.
Biodegradability difficulty: Particleboard and MDF typically lack the natural wood’s ability to biodegrade. In the long run, this can pose environmental concerns.

Pyrolysized into Charcoal

Sawdust Pyrolysized into Charcoal


Waste reduction: Taking Beston sawdust charcoal machine as an example, it can handle 0-15 m³of sawdust per hour. This effectively reduces the accumulation of sawdust.
Economic benefits: Pyrolysis technology efficiently transforms sawdust into valuable charcoal, tar, wood vinegar and biogas, achieving resource utilization of waste.
Environmental friendliness: The sawdust to charcoal project strictly adheres to environmental standards like EIA. This minimizes the impact on the ecosystem.

Why Sawdust Is Suitable for Making Charcoal?

Sawdust is the foam-like particles generated through woodworking operations in sawmills, pulp mills, etc. While sawdust is typically seen as industrial waste in the timber sector, some of its characteristics make it ideal for the production of valuable charcoal.

High Carbon Content

Sawdust is primarily composed of carbon, which is a key component for charcoal production. This presents the potential for converting sawdust into charcoal.

Porous Structure

The porous nature of sawdust provides numerous channels for the release of volatile organic compounds during the pyrolysis process. This helps in achieving a more efficient conversion of sawdust into charcoal.


Sawdust is a byproduct of various wood processing industries, making it readily available and cost-effective. This makes it a sustainable and economical choice for charcoal production.

How to Make Charcoal from Sawdust?

Pyrolysis technology is key to making charcoal from sawdust. It is a chemical degradation process that occurs at high temperatures in a low or oxygen-free atmosphere. The following presents how a continuous sawdust charcoal making machine works.

01 Sawdust Drying
Sawdust is fed into the biochar reactor by the belt conveyor. Then the moisture of sawdust is evaporated by the heat supplied from the outside, reducing it to less than 15%. Or, the customers can choose an independent dryer for drying, as shown in the video below.
02 Pyrolysis of Sawdust

In the hypoxic and micro-pressure main furnace, components in sawdust undergo decomposition, rearrangement, polycondensation, etc. forming charcoal. Typically, the whole reaction takes about 15-25 minutes.

  • Stage 1 – endothermic pyrolysis: At 220-270℃, sawdust begins to decompose and release volatile gas (CO, CO2, H2S, etc.).
  • Stage 2 – carbonization: At 270-400℃, methanol, ethylene, and other substances in sawdust are precipitated. The carbon structure in sawdust undergoes a rearrangement, forming solid charcoal.
03 Syngas Recovery
During the above reaction, a substantial amount of combustible biogas is generated. The biogas will be delivered to the cyclone dedusting system and water seal for purification. Subsequently, it enters the condenser, where wood vinegar and tar are separated. The remaining biogas enters the combustion system, providing heat for the reactor.
04 Sawdust Charcoal Cooling Collection
High-temperature charcoal from the reactor discharge safely by the water-cooled screw automatic discharger. Its temperature will be reduced to below 45℃ and be collected safely.
05 Exhaust Gas Treatment
Flue gas produced after biogas heat source utilization is cleaned by cyclone dedusting, water spray, ceramic ring absorption, and defogging plate. Finally, the flue gas meets the EU emission standard.

Testing Report of Sawdust Charcoal

Here we select local Chinese sawdust to test the quality of sawdust charcoal. The report indicates that the calorific value of the sawdust charcoal produced by our sawdust charcoal machine has exceeded 6000 kcal/kg, approximately doubling that of raw sawdust (typically 3000-4500 kcal/kg). This outstanding performance makes sawdust charcoal a reliable and efficient energy source with good economic benefits. Therefore, we sincerely recommend that you consider this project.

Note: Different types, moisture, sizes of raw materials, and technical parameters will have an impact on the biomass pyrolysis results.
