Wise management of industrial wastes is one of the most serious problems in today´s society. The aim of the present work is to suggest an alternative way to reuse the enameling waste of Company Portinari Company, Cecrisa S.A, as major component in ceramic masses to the manufacturing of electric insulators. Formulations with variable amounts of alumina, potassic feldspar and quartz were used, all containing at least 50% waste. The crude waste was firstly treated and then characterized by chemical and mineralogical analysis. The plastic molding process was used in order to produce the green samples, which were left to dry. The samples were submitted to a firing cycle previously indicated by a gresification curve for the waste. After that, the produced samples were submitted to a final test in order to estimate their dielectric rupture tension. The findings suggested a good technical compatibility of the waste considering its utilization as raw material for the production of electric insulators.
