Brazil is the largest worldwide producer of alcohol and sugar from sugar-cane and has an extensive alternative program for car fuel which is unique. In the bagasse burning process, black fumes are expelled through the chimney (fly ash recovered in the gas washer), and a clearer ash falls to the bottom of the boiler (bottom ash). Tens of thousands of tons of this fly ash (principally carbon and silica) are released into the atmosphere (airborne fly ash) every year and can be a health hazard In the production of charcoal, this residue is not dumped on the soil but is used to produce energy, and trees are saved. Conventional charcoal production in Brazil is a destructive element of natural forests. Therefore, the objective of this study is to demonstrate the feasibility of recovering fine charcoal from fly ash to produce charcoal briquettes. Results also show that the procedure adopted for the production of briquettes based on charcoal powder from the ash of sugar-cane bagasse and cassava starch as the binder is efficient, yielding briquettes with properties that meet market technical requirements.Moreover, the most representative parameters are compatible with or better than those parameters obtained utilizing other sources of charcoal. The average briquette properties obtained are: a calorific value of 25,551 kJ/kg, a density of 1.12 g/cm3, a mechanical resistance to compression of >7 MPa and a residual ash of 13.2% after burning.
