How to make use of Charcoal Dust

Article researched and posted by Maria Nakirya upon request from a CELAC Blog Guest

Charcoal dust is a residue from charcoal. It is that soot black powdery substance normally found at the bottom of charcoal sacks, charcoal selling stores or in the charcoal making areas. It results from the chip offs from the charcoal slates.

Our great grand parents used to brush their teeth with charcoal dust. This was with the help of a coffee branch, a method still used by many in rural areas that cannot afford to buy toothpaste. However, dentists discourage this practice because of health reasons.

They also used charcoal dust to heat their rooms as well as cook food using traditional stoves. This practice continues though on a minute scale, with many homes opting to throw it away. Below are beneficial alternatives for charcoal dust.

You can make banana charcoal. Here you need half (½) bucket of freshly sliced banana peelings, a quarter (1/4) basin of charcoal dust and another quarter (1/4) bucket/basin of fine sand. Thereafter, mix the sliced banana peelings with the charcoal dust, and sand. The banana sap will help to bind them. When still fresh, separate the mixture into smaller desired pieces and then bake them in the sunshine. They are then ready for use. Excess banana charcoal must be stored in a dry place.

You can also make mud charcoal, called briquettes. This is done through combining charcoal dust with mud then compressed into small rectangular blocks. For each amount of charcoal dust, mix with one quarter of mud. Briquettes save on power costs. In Nairobi women use this charcoal for home use and also earn income from sale to others. One 20-litre tin of dust when molded into briquettes is enough for use by an average African family for at least one week.

Charcoal dust is used by a factory in Kenya named “Chardust” to make briquettes that are used in hotels and poultry farms. Their briquettes are also used for grilling, cooking and warming purposes. The dust is brought to the factory which is on the outskirts of Nairobi. Here, 70 employees grind the dust with coffee, rice husks and sawdust into a mix to form the briquettes that burn longer. They are also said to be cleaner than charcoal, are smoke, smell and spark free. This helps conserve the trees.

Charcoal dust has some antiseptic, salt and odor absorbing properties. When sprinkled on freshly cut plants divisions, it can lessen the chance of infection. Whereas some farmers also mix it with soil as a fertilizer especially for vegetable and banana growing, others prefer to mix it with chicken litter and use as a fertilizer on their farms. Charcoal dust is known for its basic carbon component which natural farmers find a good media or substrate for proliferation of beneficial micro organisms in the soil.

Charcoal dust from soft wood can be put on wounds for healing. To use it, sprinkle a thick layer to the wound then tie a linen cloth bandage around. Remove after 1 to 3 days and replace with new dust to for further drying. Its anti corruptive property enables absorption and avoids rotting. It also helps to remove the unpleasant smell of wound. The only disadvantage in use of charcoal dust to heal wounds is that it dirtens the person using it. Also, one has to be careful that the charcoal dust used is not contaminated by harmful bacteria. This therefore calls for its immediate collection after its made and safe keeping.

Also, when applied to the soil, charcoal dust repels ants. Some farmers use charcoal dust to keep the ants, and especially termites away from their mud and stick structures. This is by putting a layer of charcoal dust around the structure.

    That good new s. I also make charcoal briquttes as a hobby. I mix it with saw dust and screw drive them through a pipe with a provision of a hole in the briquetttes fro quick drying and air supply. A average time for burning is one hour in a local stove. My problem is how can i produce then in bulk; can some body hep?
