Briquettes production


Waste collection and sorting

Agricultural waste material such as maize cobs, crop stems/residues, cow dung etc are acquired from farmers at a given fee to enable them attain an extra income from material they deemed waste.
Municipal organic waste such as peelings, is collected from food markets, households and institutions.
These are most times attained at no cost or very low cost.


On receiving all the waste, we sort them according to the different types and dried separately so as to ease the carbonization process. Some wastes such as Maize cobs are received dry hence taken for
carbonization directly. Others are received moist such as banana peelings they can be either dried under direct sunshine or using a constructed solar drier depending on weather conditions


This involves the conversion of waste into carbon or char. This is done by using either a constructed large scale carbonizer or a fabricated small scale carbonizer. However, during training, we advise participants that if they cannot afford the above carbonizers, they can adopt an open air method of carbonizing


The carbon material is then crushed into fine and medium particles using either an automated crusher or a manually operated crusher. The automated can either be run by electric motor or diesel engine

Mixing with a binder

The crushed carbon material is then mixed with a binder to bind the fine particles together during compression stage. The various binders that can be used include; cassava our, molasses, crushed dry
banana peelings and any other material with a high starch content


The mixture of the fine particles and binder is compressed either with an automated extruder that uses a screw system or manual extruder that uses a piston system. These compress and mold the material into different forms of briquette which is taken for drying.


This takes 2-3 days depending on the weather conditions


Briquettes are then packed in paper bags for small consumers such as homesteads and in plastic crates for large consumers such as institutions.
