 Coconut Shell Charcoal is an important product obtained from coconut shell. Coconut Shell charcoal is used widely as domestic and industrial fuel. It is also used by foundries and goldsmiths. Coconut Shell Charcoal is also used to produce activated carbon. Activated Carbon produced from coconut shell has certain specific advantages as the raw material can adsorb certain molecules and because of its density retains good strength and physical properties. ArSta eco Coconut Shell is carbonized by using destructive distillation process which produces a very superior product. Our shell charcoal is manufactured by processing shells of fully matured nuts in a modern carbonisation reactor wherein the process is clean and has a carbon negative footprint.

Charcoal Making Process Using Coconut Shells

Coconut shells as an important raw material are widely used for making charcoal in the world, in particular in the developing countries such as India, Malaysia etc. In turn, coconut shell charcoal is used in many fields by reason of its advantages and important features. For instance, coconut shell charcoal could be powdered and used for making granular activated carbon. It also could be used by goldsmiths, blacksmiths and in laundries. What is more, coconut shell charcoal is recognized as one of the best fuels for cooking because of its pleasant smell.

There are many methods of coconut shell charcoal production, but the drum method and pit method are the most widespread. In general, shell charcoal is made by burning coconut shells in a limited supply of oxygen. It is important to know that oxygen could destroy shells if the air will not be limited.  It should be used clean, fully dried and mature shells in order to get high quality charcoal.

The drum kiln is one of the most widespread methods of coconut shell carbonization. It has 3 sets which consist of 6 holes, middle and upper layers and a lid. The drum also includes a chimney which is placed on the lid of the drum. Optimum carbonization of shell in a limited supply of oxygen provides good quality charcoal.

So, first of all, the raw shells must be put into the drum, leaving a 4 inch space in the centre of the drum, which plays an important role during carbonization allowing the flow of smoke. To start carbonization, a fire should be started in the middle of the circle using a piece of a coconut shell. Then, all the free space in the drum should be filled with raw materials. When the flames flare up, the chimney and the lid should be attached. The middle and the upper sets must be closed.  When some of shells shrink to the bottom, more coconut shells should be added up to the brim of the drum. It is done to fіll thе vоlumе rеductіоn tо maxіmіzе cаpаcіtу fоr burnіng. The process of carbonization begins at the bottom of the drum and goes up. When the carbozation is finished, it can be seen a glow in the 6 holes of a set of the particular zone. When the holes of the bottom zone indicate this glow it means that the bottom set is closed, while the middle set is opened. When the carbonization in the middle zone is completed, its holes are closed and the bottom holes are opened. Сlosing of the top set of the holes after the full carbonization in the top region stops the airflow into the drum. The charcoal could be gotten and packed after about 8 hours when the drum is cooled. It is important to check if the drum is completely cooled as little fire inside could rekindle the charcoal and burn it to ashes. In general, using drum method 30 thousand of coconut shells are needed to produce 1 ton of coconut shell charcoal.
