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.
Availability
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.
Proven Capability to Produce High-quality Biochar
Biochar can be used for soil improvement, water treatment or industrial adsorbents, and the market demand is stable.
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 hasexceeded 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.

Sawdust Charcoal Making Process
The entire sawdust recycling process mainly includes crushing, el secado, feeding, carbonización, discharging, combustible gas recovery, exhaust gas treatment, and sawdust briquette production.
01 Preprocessing
- Crushing (optional): The crushing system processes sawdust into target sizes (less than 20mm).
- Drying (optional): The drying system processes the sawdust to a moisture content of less than 15%.
02 Carbonization
- Feeding: The sawdust is automatically fed into the furnace via a conveyor belt, screw feeder or Z-Belt.
- Carbonization: After heating the main furnace, the temperature gradually rises. The initial temperature helps dry out some of the moisture in the sawdust. When the temperature reaches 250 degrees Celsius, demethylation begins. Combustible gas starts to generate. At 280 degrees Celsius, the exothermic reaction begins. The hydrocarbon molecules split into smaller carbon molecules and hydrogen. charcoal begins to be produced. As the temperature hits 450 degrees Celsius, aromatic ring compounds begin reacting.
03 Discharging
- Sawdust charcoal: Through a three-stage water-cooling discharger, sawdust charcoal below 45 degrees Celsius is collected.
- Tar & wood vinegar collection (optional): Via the condenser, tar (biomass oil) and wood vinegar separate out and are collected separately.
- Sawdust charcoal briquette making (optional): After being processed by the sawdust charcoal briquette machine, the original shape of charcoal can be made into the required shape, such as round, cuadrado, stick, etc..
04 Combustible Gas Recovery
- After condensation and sulfur removal treatment, combustible gas can be recovered and reused.
- We can also introduce the excess heat from the carbonization furnace into the dryer to recycle the combustible gas, thereby saving fuel for the dryer.
05 Exhaust Gas Treatment
- The emission gas is treated by a spray tower, water curtain de-dusting tower, and cooling tower. The processed emission gas meets the EU emission standards.
- Weiwa Group provides high-standard customized exhaust gas treatment system.
Features of Sawdust Charcoal Making Machine
Equipped with Alarm Device
The PLC electric cabinet has an alarm device, and there will be an alarm display and an alarm for some electrical failures.
With Explosion-proof Water Seal
There is an explosion-proof water seal at the combustible pipeline (to prevent abnormal pressure of combustible gas in the equipment)
Variable Frequency Fan Guide
The direction of the gas in all pipelines is led by the fan (the fan is variable frequency), and it will be displayed on the PLC when the pipeline is blocked
High Heat Efficiency
The material is not in contact with the flue gas and is not polluted by hot air.
Good Energy-saving Effect
The heat utilization rate of this equipment is higher, the use of air heat ex-changer can effectively improve the thermal efficiency by 5-10%, and the energy saving effect is good.
How to use Sawdust Charcoal Making Machine to make profits
Sawdust to charcoal is a circular economy solution. Sawdust are converted into biomass charcoal resources. Biomass charcoal can be applied to both the cultivation industry and the food processing industry. This allows for sustainable development and a truly closed-loop solution.
Guaranteed Access to Carbon Credit Trading
- High carbon content
- 100% Natural and environmentally friendly
- Trap large amounts of carbon dioxide and Improve carbon footprint
- Be used for market transactions, such as carbon credits, carbon offsets
Soil Amendment
- 80% microporous structure to improve soil aeration and drainage
- Provide some trace elements, such as potassium, magnesium, zinc
- Alkalinity and ion exchange helps adjust soil pH and save on fertilizer costs
High-Quality Sawdust Biochar Output
The sawdust charcoal not only finds renewed application in the wood processing industry as a fuel but also has extensive uses in various other industries.
Hookah Charcoal
Sawdust charcoal, after undergoing special treatment, can be used as a flavorful hookah charcoal. It is employed in hookah pipes for people to enjoy, helping to relax the mind and body.
BBQ Charcoal and Cooking
Sawdust charcoal is easy to light. It is ideal for home cooking and BBQ. You can purchase charcoal briquette machine at Weiwa Group.
Policy subsidy application
Some countries or regions provide subsidies or tax incentives for the use of biomass energy, such as the EU’s “Green New Deal” or China’s renewable energy support policy.
Sawdust biochar is characterized by good stability and slow decomposition. Mixing it into the soil helps with carbon sequestration, reducing the concentration of carbon dioxide in the atmosphere.
