Coconut shells can be processed into coconut shell charcoal by pyrolysis technology. Coconut husks don’t have many uses by themselves. Usually, coconut shells are thrown away as trash. However, when coconut shells are processed into coconut charcoal or coconut shell biochar, it has a wide range of uses and economic benefits in various industries.
What is Coconut Shell Charcoal?
Coconut shell biochar refers to an environmentally friendly energy source formed by heating coconut shells at high temperatures and anaerobically. The hard coconut shell is part of the coconut. After being treated by a charcoal making machinery, it can be converted into biochar. Normally, in order to guarantee the quality of coconut shell charcoal, the moisture content of coconut shell is less than 15%. We can also convert coconut shell charcoal into different shapes of charcoal by subsequent processing.
Coconut shell charcoal is composed of carbon, hydrogen, oxygen, nitrogen and small amounts of other elements. Coconut shell charcoal contains mineral elements including potassium, sodium, calcium, magnesium and so on. In addition, it has a pore structure. This structure makes biomass charcoal have good adsorption and storage properties. And it is suitable for various application fields. It is economical and environmentally friendly.
What are the Components of Coconut Shell Charcoal?
After being processed, the coconut shell turns into biochar. The composition ratio of this biochar varies with many factors, for example, the temperature and time of pyrolysis. The following table shows the composition ratio data of processed Chinese coconut shells. The tested coconut shells originated in China. Therefore, this test result is for reference only. If you have local raw materials, you can send them to Beston Group for testing. We will issue a detailed report to you. Please see this test result.

What are Coconut Shell Charcoal Benefits?
As an economical clean energy, Coconut shell charcoal has many features. See the following descriptions:
- Renewable feature: Coconut shell charcoal is made from renewable agricultural waste (coconut shells) by coconut shells charcoal machine. It helps reduce agricultural waste.
- Porous structure: Its surface has millions of tiny voids.
- High carbon content: It is made of coconut shell that is rich in carbon. The carbon ups to 50-55%.
- High calorific value: Coconut shell has high cellulose content and moderate density. The ash content of coconut shell charcoal is relatively low. Therefore, coconut shell has a higher calorific value.
- Stability: The high carbon content and low volatility of coconut shell charcoal give it high stability.
What are Coconut Shell Charcoal Uses?
The uses of coconut shell charcoal are wide. Because this charcoal has high carbon content, porous structure and high calorific value, it can be used in the following sectors:
Agricultural sector Soil remediation: It can be used for soil improvement and remediation, such as increasing soil nutrients and improving soil structure. Most importantly, it can help improve crop yields.
Industrial sector Heating fuel: It can be used as a heating fuel in factories, such as cement factories, brick factories, power plants, boiler factories and so on.
Metallurgy: Coconut shell charcoal is a material needed for metallurgy.
Animal husbandry sector Feed: Coconut shell charcoal is added to the animal feed. This feed improves the digestive system of the animals. Thus, it is helpful to promote animal growth.
Odor management: Coconut shell biochar can absorb odors, such as manure, ammonia, and so on.
Catering sector Barbecue charcoal: Many restaurants and families now choose economical, high-calorific coconut shell charcoal as barbecue charcoal.
Carbon credit sector Carbon market transactions: Biochar can be used for carbon market transactions, such as carbon credits. If you choose this way, it is a long-term process.
How to Make Coconut Shell Charcoal?
In addition to the following description, here is a case video for your reference.
- Put coconut shells into the biochar reactor.
- Coconut shell charcoal is formed when the coconut shell is processed for 15-25 minutes.
- Coconut shell charcoal is discharged with the automatic water-cooling discharging system.
What Factors Affect the Composition Of Coconut Shell Biochar?
The element content of coconut shell biochar is not fixed. Many factors affect the quality of coconut shell charcoal. Please see the factors affecting the elements of coconut shell biochar:
Types of coconut shells Different types of coconut shells have different chemical compositions and structural characteristics. For example, coconut shells, which are denser in wood fibers, contain more carbon.
Moisture content The higher the moisture content of the coconut shell, the lower the calorific value of the biochar. Coconut shell biochar with high moisture content needs to consume more energy to evaporate water when processed. This process reduces the available energy per unit mass of effective fuel. It results in a decrease in calorific value.
Carbonization temperature and time The temperature during pyrolysis affects the calorific value of the coconut shell biochar. Higher carbonization temperatures generally result in more carbon being retained.
Ash content The ash content in coconut shell biochar has a certain influence on the calorific value. Higher ash content may lead to more ash in combustion. It reduces the mass of effective fuel thus lowering the calorific value.
Carbonization method Different pyrolysis methods, such as slow pyrolysis and fast pyrolysis, will affect the calorific value of biochar. Typically, slower pyrolysis results in a higher calorific value because it better preserves the carbon structure of the original coconut shells.
Pyrolysis Quality The quality control of the pyrolysis process affects the calorific value of the biochar. If the quality process is not done properly, it may cause some carbon to be destroyed, thereby affecting the calorific value.
Choose a Suitable Way to Manufacture Coconut Shell Charcoal
Coconut shell charcoal has many applications because of its perfect features. It can be used in the industrial sector, catering sector, agricultural sector, etc. If you are doing coconut shell charcoal manufacturing business, choose a cost-effective resources for coconut shell supply.
