How to Make Charcoal from Wood

Currently, there is a global energy crisis due to factors such as energy supply-demand imbalance, depletion of fossil resources, and environmental pressure. As a result, charcoal, a kind of energy source with the advantages of renewability, high calorific value, and a wide range of applications, has become a significant option for people who seek alternative energy sources. This article will provide a detailed explanation of how to make charcoal from wood.

How to Make Charcoal from Wood

The carbonization process is the key step in how is charcoal made from wood. Beston Group has developed advanced modern charcoal making machines to improve the efficiency and quality of charcoal production. Now let’s see how charcoal is made from wood together.

1. Raw material pretreatment:

Pretreatment includes removing impurities, crushing and drying, etc. The normal feed size of Beston Group’s charcoal machine is less than 20 mm. For wood, the optimal size is 8-12mm, with a moisture content below 15%. If the raw material size is too large, a crusher is provided, and a dryer is provided for excessively wet materials. Thus, concerns about raw material suitability can be alleviated.

2. Decomposition and carbonization:

After pretreatment, the constant weight feeder transits wood into the furnace for pyrolysis by the belt conveyor. The furnace is in a high-temperature and low-oxygen environment. During the pyrolysis process, the temperature rises to 300-600 degrees Celsius, causing the wood raw material to undergo molecular decomposition. After approximately 20 minutes, the organic matter in the wood will be converted into carbide.

3. Charcoal Slagging:

After the carbonization process is completed, the carbides produced by high-temperature pyrolysis need to go through the process of smoke discharge and sulfur removal through the dedusting system. In this way, it removes impurities in the carbides and can obtain high-quality charcoal. After that, the charcoal will be discharged from the powder discharge port.

4. Briquetting and molding:

The charcoal briquette making machine can convert the charcoal into different shapes according to customers’ requirements.

The above are the general steps of how to make charcoal from wood. If you have doubts or want to know more about how to turn wood into charcoal through carbonization, please contact Beston Group. We will try our best to answer your questions.

How To Make Wood Charcoal

Wood Raw Materials For Making Charcoal

Wood trunks, branches, twigs, barks

The trunk of the wood usually has a large volume and high wood fiber content, making it ideal for making charcoal. The leftover bits and pieces of a tree such as branches, twigs, and barks are relatively small in size but can also be collected in large quantities and used for making charcoal.

Waste wood scraps during wood processing

Wood chips, sawdust, and other waste scraps during wood processing are very low in cost and can be collected in large quantities and used as raw materials for making charcoal.

Shapes of Charcoal

Beston Group’s wood charcoal making machine can produce charcoal in a variety of shapes. It depends on customers’ requirements and application areas. The common shapes of charcoal are hexagon, square, and circle. If you want to make some different shapes, Beston Group can also provide professional customized machine to satisfy your needs. If you have such needs, please contact us.

Application Fields of Charcoal

Wood Biochar Fertilizer
Wood Biochar Animal Feed
Biochar Fuel For Factory
Wood Charcoal For BBQ


Charcoal can be used as a soil conditioner and in organic fertilizer manufacturing, which can effectively maintain the water storage and fertilizer retention capacity of soil and promote nutrient absorption, and improve the utilization rate of fertilizer. At the same time, this is also an effective means of carbon storage and earning carbon credits, which can bring both environmental and economic benefits.

Animal husbandry:

Biochar animal feed is becoming increasingly popular. It can reduce methane gas emissions from ruminants by regulating the digestive capacity of livestock, which is beneficial to the environment.


Charcoal serves as an efficient fuel in steel, cement, chemical, and other industries. In addition, the unique microporous structure and strong adsorption capacity of charcoal contribute to environmental protection in waste gas and sewage treatment.

Daily life:

Charcoal plays the role of fuel in cooking and home heating, barbecues, and survival in the wild. It can also be used to create artistic works and charcoal crayons. It can also absorb the dirt in rainwater and sewage to protect the purity of groundwater.

During the operation of charcoal machine, the material does not come into contact with the flue gas and won’t be polluted by hot air, bringing a doubled utilization efficiency compared to single-layer externally heated structures. In particular, the continuous biochar making machine produced by Beston Group has significantly improved production efficiency. Compared with the traditional carbonization kiln, it is equipped with a professional cooling system, so that it does not need to go through a long natural cooling process, and at the same time, the equipment allows for simultaneous material feeding and charcoal discharging. These make full use of time and the heat energy generated during the carbonization process, thereby significantly increasing production efficiency.


First of all, the charcoal machine adopts a triple-sealing design, ensuring its airtightness and enhancing safety and reliability. Secondly, it has equipped with an automatic igniter and a steady flame device, which can effectively prevent explosions of the furnace. Furthermore, it adopts the design of closed-air feeding, which can prevent the outside air from entering the furnace and ensure the safety of the feeding system and operators. Lastly, there is a professional explosion-proof device at the end of the equipment to further enhance its safety.

Environmental friendly:

Firstly, the biochar production equipment helps to recycle various waste biomass and garbage, contributing to environmental protection. Secondly, it is equipped with an advanced water cooling system and filtration system to address the high-temperature flue gas generated during the carbonization process. This ensures that the emitted flue gas meets environmental standards. Thirdly, clean energy is used in the heating process to reduce environmental pollution. Fourthly, the sewage can be reused without generating sewage discharge.
