Analaysing composition of the production of coal briquettes

The unsustainable nature of agricultural and rural waste results in environmental pollution and may ultimately lead to complete depletion of the natural resources. Agricultural wastes are recognized as having “hidden” economic value. The uses of agricultural residue include direct burning as a fuel for domestic and industrial cooking/heating and production of biogas and biomass for power generation. In addition to its use in raw forms as fuel, agricultural wastes are a form of renewable biomass and can be processed into other solid forms (for e.g. briquettes, charcoal, pellets) or into liquid fuel through pyrolysis or gaseous fuel through gasification or biogas. Different technologies for handling this type of waste, such as composting, animal fodder, briquetting, biogas, construction materials, and silicon carbide, are discussed in this chapter.
