As people are knowing biochar deeper and deeper, the biochar making machine has become more and more popular, especially in the European market. More and more people are considering investing or have invested in the machine. In this page, we will introduce the biochar machine by answering the questions below, and will also introduce Beston’s advantages and strength in this field.

What is Biochar? Why is Biochar So Valuable?
Biochar refers to a charcoal-like substance that’s made by burning organic material from agricultural and forestry wastes (also called biomass) in a thermal decomposition conversion process called pyrolysis. During the pyrolysis process without oxygen, the biomass materials are burned in a container (generally called biochar reactor) with high temperature. Then the organic material in biomass converted into biochar, a stable form of carbon that can’t easily escape into the atmosphere. Biochar is more efficient at converting carbon into a stable form by far and is cleaner than other forms of charcoal. Have a look at different shapes of biochar:






Why is biochar so valuable?
The biochar has many unique characteristics, which can be widely applied in many industries. You never need to worry about its sale and usage.
- High Output Rate – for making high-quality charcoal from biomass;
- Wide Applications – used for recycling/heating/cooking, etc.;
- Lower Acidity – for soil improvement;
- Stable – for carbon fixation and emission reduction.
About Biochar Making - Raw Materials/ Production Process/ Equipment
Raw Materials Suitable for Bio Charcoal Making Machine
Almost all the agriculture or forestry wastes can be used for making biochar. Here are some examples for your reference. If you are not sure if your materials can be used for bio charcoal making, please contact us for the accurate answers and related testing.
- Biomass waste: such as rice husk, coconut shells, palm kernel shell, bamboo, wood chips, sawdust, olive husk, coffee husk, fruit husk, hazelnut husk, oak, jute stalks, sugarcane bagass, peanut husk, sunflower stalks, plant straw, peach pit, etc.
- Sludge: such as municipal sludge, river sludge, industrial sludge;
- Domestic waste: Municipal domestic waste.












How to Make Biochar?
The whole biochar making process is finished under the help of biochar making machine, which has been divided into 3 parts: drying, endothermic pyrolysis and carbonization.
- Drying: in the drying stage (inner barrel), the temperature is around 150℃. The external and internal moisture of the raw materials are evaporated by the heat supplied from the outside, and the shape of the raw materials does not change at the same time.
- Endothermic pyrolysis: in the endothermic pyrolysis stage at 220-270℃, the raw materials begin to decompose and release gaseous products (such as CQ, CO2, H2S, etc.). The chemical composition of the raw materials begin to change, and the temperature at which different materials begin to pyrolyze is different. Materials with a low degree of deterioration also start at a lower temperature for pyrolysis.
- Carbonization: the temperature in the carbonization stage us 270-440℃, and the reaction is mainly polycondensation and thermal decomposition in the portable biochar kiln. A large amount of volatiles are precipitated from the raw materials, and almost all products such as methanol, and ethylene precipitated in the carbonization process are produced in this stage.
What is Biochar Making Machine?
In the production process, the biochar making machine takes advantages of the agriculture wastes or forestry wastes that are rich in lignin, cellulose, hemicellulose, such as straw, sawdust, rice husk, fruit shell, coconut shell, palm shell, tree bark, logs, etc. In the high-temperature oxygen-free pyrolysis process, the carbon and hydrogen elements in the raw materials are converted into high-calorie mixed combustible gas, biochar and by-products: wood vinegar and tar.
- Wood vinegar: anti-insect fungicide to protect crops; pesticide intermediates to kill pests; soil amendment to improve the quality of soil;
- Tar: basic raw material for smelting bio-diesel;
- Combustible gas: heat the carbonization furnace for secondary use.



Where/How Will You Use a Biochar Making Machine? - Application Scenarios

Soil Remediation and Improvement?
The generated biochar from biomass can significantly increase soil PH, change soil texture, and increase base exchange capacity, thereby causing soil CEC to increase. It affects the absorption of nutrients by plants and improves soil organic matter. On the one hand, biochar can adsorb soil organic molecules and promote the polymerization of small organic molecules to form SOM through surface catalytic activity. On the other hand, the extremely slow decomposition of biochar itself contributes to the formation of humus and promotes the improvement of soil fertility through long-term action. Biochar can also change the form of toxic elements, reduce pollution during plant growth, promote the uptake of nutrient elements, and promote plant growth.

Carbon Sequestration and Emission Reduction?
Biochar is formed through the carbonization process. It is essentially what we use plants to capture carbon dioxide from the atmosphere and convert it into a stable form of carbon that looks like charcoal powder. Biochar can hold carbon in the ground for hundreds of years. The carbon dioxide captured by plants through photosynthesis is converted into biochar, which is sequestered underground and isolated from the atmosphere for hundreds of thousands of years. This is a great way to remove carbon, help fight climate change and reduce carbon emissions.

Industrial Hookah Charcoal or Barbecue Charcoal Production?
Beston biochar making machine adopts carbonization technology with double drum and double fire zone. Through the high temperature dry distillation, it process the waste biomass such as sawdust, coconut shell, straw, rice husk, peanut shell, palm shell, etc. to charcoal, tar, wood vinegar and combustible gas. After that the biochar can be mixed with binder and further processed into barbecue charcoal briquette, shisha cube and other charcoal products. In this way, a fire-resistant, smokeless, and odorless mechanism charcoal can be produced, which not only effectively solves the problem of felling trees, but also makes full use of some abandoned agricultural wastes. What’s more, it develops shisha charcoal that is more economical and popular in the Middle East and European and American markets.

Fuel Alternative Solution for Industry Plants?
Beston Group adopts carbonization technology to obtain charcoal from biomass waste. The finished biochar can be sued as alternative fuel in many industries, such as cement plants, boiler plants, brick plants, ceramic plants, power plants, ships, etc. By this method, it can not only save a lot of money for replacing traditional energy sources, but also open up a new way of revenue for high-energy-consuming factories such as power plants and boiler plants.

Agricultural and Forestry Waste Recycling?
The whole biochar making process adopts the carbonization method of double drum and double fire zone to obtain biomass charcoal, tar wood vinegar and combustible gas by carbonizing agricultural and forestry wastes through high temperature dry distillation (wiki). The finished biochar can be sold or deeply processed into activated carbon, and the combustible gas can be connected to the generator to generate electricity (currently this technology has yet to be broken through). In this way, it not only effectively solves the pollution problem of agricultural and forestry wastes, but also opens up a new way of income for agriculture and forestry, and can also greatly alleviate the energy shortage.
