RDF is fuel derived from waste, which is used to fire industrial kilns. Thanks to a machine known as the Tyrannosaurus, which has the capacity to grind large amounts of waste, it is possible to reuse what is nonorganic and nonrecyclable. In practice, this waste becomes fuel, giving rise to a new value chain.
Before becoming fuel, solid urban waste (household and commercial) and nonhazardous industrial waste (Class IIA and IIB) undergo selection and mechanical homogenization to obtain the best proportion of wet and dry materials.
Located in Paulínia, in upstate São Paulo, the Tyrannosaurus has a daily processing capacity of 1,000 to 2,000 metric tons.
RDF can be used in cement kilns, boilers and biomass plants. In addition to generating efficient heat for the operation, it completely destroys the waste, without generating environmental liabilities while also preserving natural resources such as coking coal.
