Abstract

The agro and industrial activities are actually responsible for the production of large amounts of solid wastes in Brazil. The use of industrial wastes as alternative raw materials into ceramic products has been widely developed. The typical materials used in the ceramic formulations present a large diversification of chemical compositions, what allow the incorporation of different types of waste materials in the ceramic mixture. Brazil produces a massive amount of coffee and the lack of adequate landfill areas available to dispose the coffee’s husk ash reject material are causing an ambiental problem for the agro-industry. This work describes research carried out on the thermal characterization and X-ray diffraction of coffee’s husk ash reject and its possible use in the ceramic industry.
