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.

Pyrolysis
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.

Cooling
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.

Packaging
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.
