What is the process of producing sawdust biochar briquette


With the growing emphasis on sustainable energy and reducing carbon footprints, sawdust biochar briquettes are increasingly gaining attention as an eco-friendly alternative to traditional fuels. These briquettes are made from sawdust, a by-product of the wood industry, and transformed into biochar—a highly carbon-rich material. The process of producing sawdust biochar briquettes involves several critical steps, from collecting raw materials to the final production of the briquette. This passage delves into the detailed process of producing sawdust biochar briquettes, highlighting the key stages involved.

Collection of Raw Materials

Sourcing Sawdust

The first step in producing sawdust biochar briquettes is the collection of raw materials, primarily sawdust. Sawdust can be sourced from various locations, including sawmills, woodworking shops, and furniture manufacturing units. Ensuring a consistent and ample supply of sawdust is crucial for continuous production.

Quality Control

It’s essential to collect sawdust that is clean and free from contaminants such as metal, plastic, or other non-wood materials. Contaminants can affect the quality of the biochar and the efficiency of the briquetting process.


Importance of Drying

Sawdust typically contains a significant amount of moisture, which can impede the carbonization process and reduce the quality of the biochar. Therefore, drying the sawdust to a moisture content of around 8-12% is a critical step.

Drying Methods

Sawdust can be dried using natural methods, such as air drying under the sun, or using industrial drying equipment like rotary dryers. Industrial drying is more efficient and can handle larger volumes of sawdust.


The Carbonization Process

Carbonization involves heating the dried sawdust in the absence of oxygen to produce biochar. This process is usually carried out in a carbonization kiln or a retort. The sawdust is subjected to temperatures ranging from 300°C to 500°C, which breaks down the organic material and results in the formation of biochar.

Monitoring and Control

The carbonization process requires careful monitoring to ensure optimal temperature and time settings. Over-carbonization can lead to the formation of ash, while under-carbonization may result in incomplete conversion of sawdust to biochar.

Grinding and Mixing

Grinding the Biochar

Once the carbonization process is complete, the biochar is ground into a fine powder. This step is crucial for creating a uniform mixture that can be easily molded into briquettes.

Adding Binders

To enhance the binding properties of the biochar, a binder is often added. Common binders include starch, molasses, or clay. The binder helps to hold the biochar particles together, ensuring the briquettes maintain their shape and structural integrity.


Briquette Pressing

The final step is the briquetting process, where the biochar-binder mixture is fed into a briquette press. The press applies high pressure, compressing the mixture into a compact, dense briquette. There are various types of briquetting machines available, including piston presses, screw extruders, and roller presses.

Cooling and Packaging

After briquetting, the briquettes are allowed to cool and harden. Once cooled, they are packaged for storage or distribution. Proper packaging is essential to protect the briquettes from moisture and physical damage during transportation.


The process of producing sawdust biochar briquettes is a meticulous one, involving several stages from raw material collection to the final briquetting. Each step—drying, carbonization, grinding and mixing, and briquetting—plays a crucial role in ensuring the quality and efficiency of the final product. Sawdust biochar briquettes offer a sustainable and eco-friendly alternative to traditional fuels, making them an attractive option in the quest for renewable energy sources. By understanding the detailed process involved, producers can optimize their operations to produce high-quality biochar briquettes that meet market demands and contribute to environmental sustainability.

What is the process of making small scale biochar briquette

Biochar briquettes are an eco-friendly and sustainable alternative to traditional charcoal. They are made from agricultural waste, such as crop residues, wood chips, and other organic materials, which are then converted into a carbon-rich product through a process called pyrolysis. Making small scale biochar briquette involves several steps, including raw material preparation, pyrolysis, cooling, and packaging.

Raw Material Preparation
The first step in making biochar briquettes is to collect and prepare the raw materials. This involves gathering agricultural waste, such as rice husks, coconut shells, or sawdust, and drying it to remove any moisture. The dried material is then ground into a fine powder, which will be used as the base for the briquettes.

Once the raw materials are prepared, they are subjected to pyrolysis, a process that involves heating the material in a low-oxygen environment. This is typically done in a specialized kiln or retort, where the temperature is carefully controlled to ensure that the material is converted into biochar without being burnt. The pyrolysis process can take several hours, depending on the size of the batch and the type of material being used. There are types of carbonization machines for your choice.

After the pyrolysis process is complete, the biochar is allowed to cool down slowly. This is an important step, as it allows the biochar to retain its carbon content and prevents it from igniting. Once cooled, the biochar is then ground into a fine powder, which will be used to make the briquettes.

Briquette Making
The final step in making biochar briquettes is to mix the biochar powder with a binder, such as starch or molasses, to help the briquettes hold their shape. The mixture is then pressed into molds to form the briquettes, which are then left to dry for several days. Once dry, the briquettes are ready to be packaged and sold.

The finished biochar briquettes are packaged in bags or boxes for easy transport and storage. They can be used for cooking, heating, or as a soil amendment in agriculture. Biochar briquettes are a sustainable and renewable energy source that can help reduce greenhouse gas emissions and improve soil health. Visiting:
