The thermal decomposition of biomass in the absence of oxygen produces a fine grained residue that has a high carbon content which is called biochar. It is basically a form of charcoal that is useful for certain biochar making machine. The production process also gives other solid, liquid and gas products.
When biomass decomposes naturally in the presence of air, it produces large amounts of carbon dioxide and methane, which vitiate the atmosphere. Biochar is a form of carbon that can be put into the ground, and reduce the greenhouse gas formation. Biochar is porous and if added to soil can help it to retain water and nutrients thus making the soil healthier and promoting plant growth. This can help in reducing the need for water and fertilizer.
Biochar can be produced through the use of a biochar making machine that are pyrolysis systems that use the process of baking the biomass without oxygen. Pyrolysis produces gases that can again be burnt to release heat, thus making the process self sustaining. Biochar production is enhanced when more oxygen is excluded.

Ovens used in the production of biochar are low-tech and can be used to burn yard waste, agricultural waste, and even plastic and old tires, that otherwise would have made their way into landfills and cause greater environmental concerns. A biochar making machine can process many kinds of biomass, like sawdust, coconut shell, wood, rice husk, palm shell, and bamboo and make them all into charcoal. Use can also be made of sludge from industries and municipalities that have a lot of organic content.
Charcoal and other combustible gases are produced when temperatures in the machine exceed 100 degrees Centigrade. The gas requires to be first purified and its sulfur content removed, before it is processed further. It then passes through a condensing system to remove tar. The gas that is leftover can be used in the furnace or for drying biomass, leading to savings in costs of fuel. The charcoal, or biochar, is allowed to cool through built in cooling systems that brings it to temperature of less than 30 degrees Centigrade.
Besides the charcoal this machine will also have tar and wood vinegar as by products, both of which have their own uses. This biochar has a higher calorific than coal and is thus more eco-friendly. Its use as a fertilizer comes from the the presence of many micro-elements like phosphorus, nitrogen, manganese, and calcium, besides others and can be of great help in improving soil quality.

Most machines that are capable of producing biochar will do so continuously without any need for interruption to retrieve the products that the pyrolysis produces.
