New techologies--Turning stone waste to glass
According to the Brazilian Ministry of Science Web site report, the Brazilian Ministry of Science and Technology Research Institute, has recently developed technologies of using the used of decorative stone (eg marble, granite, etc. scraps as raw material) to manufacture glass. The invention also solve environmental problems when cutting stone.
The invention by the Brazilian military academy materials science experts, physicists Micceri Babisike chair. The use of marble and granite scraps in manufacturing glass, need to add some oxides, such as calcium carbonate, commonly used in the production of glass, silica, and scraps of stone, sand, calcium carbonate, etc., together with a certain proportion of mixed to enable them to maximize the glass close to the commercial element.
Take advantage of these scraps, it could significantly reduce environmental pollution, In addition, it can also reduce the use of sand, to reduce the destruction of sand resources, and the third is the environmental benefits of the cutting process of stone left in the soil by iron filings , steel scrap formation of iron oxide, can be reused, this material can be glass, the coloring agent, manufacture of green glass, sell very well in the market.
Micceri Babisike have used this technology to create four models of glass products, water resistance, light transmission, etc. have passed the performance appraisal
