The Use Of Sugar Factory Sludge As Alternative Raw Materıal For Sustainable Cement Producing With Industrial Symbiosis

Abstract

Construction increases in parallel with the population growth and development in the world. The expansion of the reinforced concrete construction system and the rapid development of its techniques have been increasing the need for cement, which is the most important component of concrete, day by day. Cement industry is the leading-sector among the sectors where natural resources are most used. The scarcity of natural resource is the one of the biggest obstacles in the industry. During sugar production, unwanted substances present in the raw sugar are precipitated with lime milk [Ca(OH)2] and CO2 gas. Lime-containing sludge is occurred with this process. The quite amount of this sludge causes environmental problems. The use of sludge, originating from the sugar factory, as an alternative raw material in the cement industry reduces the use of non-renewable natural resources and prevents the rapidly depletion of natural resources. The purpose of this study is to demonstrate the sustainable production of cement will be achieved with industrial symbiosis.
