This paper describes the development of an inorganic alternative to coal or coal replacement for bentonite bonded molds (greensand molding) and the realization in an operating foundry. Through a time period of 1.5 years, Componenta Foundry changed in many steps from a classical green sand system to a coal free system, based on ENVIBOND developed in the GO-APIC project and further development as an S&B project. At Componenta Foundry, the percentage of casting defects or scrap did not increase. There was a tendency of an increase in stress (scabbing) defects and of a decrease in penetration defects. Benzene emission is reduced by 40%, odor emission has lower values (not statistically proven). Visible is less smoke in the foundry, especially at the cooling line. The benefits for health and emissions are clearly seen. 展开更多
