Resumo: Brazil is one of the main producers of colored gemstones, and Rio Grande do Sul is the state with the greatest production of agates, amethysts and citrines. This sector is preponderant in the economy of the regions of the Upper Uruguai and Middle Plateau, but it faces technological difficulties, among which we can highlight the large volume of gemstones exported in rough state, with low added value, and the low efficiency equipment. Another problem is the sheer volume of waste generated without the adequate treatment and appropriate place for disposal. The purpose of this study is to conduct a diagnosis of the processing of the gems, identify the types of waste generated and the importance of the implementation of environmental management for this industrial sector and propose an alternative of SiO2 use (a residue from the processing of Agates) as a support material for the compounds based on iron oxides.
