Today, fuel prices are very high. The beauty of these high fuel prices is that you can now save money by making fuel briquettes for use in your own home cooking and in addition you can still make a reasonable income by selling excess briquettes to your neighborhood. Making fuel briquettes can be a sustainable business since most of the raw materials used are almost free. Your customers will be happy to buy cheap and clean fuel from you, and your neighborhood will be happy with you for helping keep their environment clean.

Biomass as a renewable energy source is defined as biological material from living, or recently living organisms. In many countries, people are growing crops and keeping animals. The waste from crops and animals are biomass material that can be used in making fuel briquettes. Agricultural waste materials such as rice husk, coffee husk, coir pith, jute sticks, bagasse (sugarcane waste), groundnut shells, sawdust, mustard stalks, cotton stalks, maize/corn, wheat husk, cattle waste, grass, leaves and cassava can all be used in making fuel briquettes.

CONCLUSION
In future, charcoal briquettes may replace lump charcoal made from trees and firewood. Lump charcoal and firewood are natural and trying to compare lump charcoal and briquettes is wrong. The idea is to have people to stop using wood charcoal in favor of agricultural waste briquettes. By training the people, especially people in developing countries, on how to convert their agricultural waste into charcoal briquettes; we shall have moved an additional step towards the reduction of deforestation that is becoming very common in many countries. The beauty of briquetting agricultural waste into fuel is that if structured under the supervision of carbon credit consultant, it can earn people additional income from compensation from carbon credits. The market for carbon credits is poised to turn out as the most lucrative market in the future.
