Sanitser, an innovative sanitary ware body, formulated with waste glass and recycled materials

摘要

Abstract In the present paper, the results of ?￠????Sanitser?￠???? Life European project are presented. The aim of this study was to reduce the firing temperature for ceramic body (from 1250 to 1170 ???°C). This was achieved substituting feldspar and quartz with recycled blend materials and a little percentage of flux (less than 3%); in a sanitary ware vitreous china formulation a waste glass, granitic materials and fired broken ceramic pieces were introduced. Tests performed on the Sanitser formulation showed that it has the same final physical-chemical characteristics of the industrial vitreous china (VC) body. Besides, different ceramic pieces (wash basin, bidet and WC pan) were compared with VC production. The results showed that Sanitser body can replace vitreous china in the sanitary ware production. In this project, the firing temperature of the ceramic body is reduced significantly with a supposed decrease of the CO 2 emissions. In Sanitser formulation, about 43.6% of recycled materials that would end in dumps were utilized.
