More than 50,000 tons of charcoals are used annually in Iran, which will increase to 100,000 tons per year, taking into account the amount of charcoal exported to the Arab countries of the Persian Gulf. In order to produce the charcoal needed by the country in the traditional way, more than 300,000 tons of wood are cut and collected from the trunks and branches of trees every year, which will lead to the destruction of the country's forests and green resources. Agricultural by-products, especially rice, cocoa, rubber, pineapple and sugarcane, are produced in large quantities all over the world. Asia alone produces 4.4 billion tons of solid waste annually. The amount of agricultural solid waste produced in Ahvaz city is 2,500,000 tons, almost all of this amount is related to sugarcane cultivation and industries that exist in this province. Wood waste, sugar cane and grass are the most prominent sources of biomass energy and if managed properly, they can be used as a raw material to produce charcoal and create renewable and sustainable energy. The general purpose of this article is to investigate different methods of producing compressed coal from agricultural waste and the factors affecting its production.
