Abstract

At one of the steps involving the casting of metals are used molds that give the desired shape and volume to the liquid metal to be fused. These molds are constituted by sand and some organic or inorganic binders to improve the adhesion of the sand. This process is generated the waste foundry sand (WFS), which is primarily discarded in landfills themselves or others, becoming an environmental liability of large proportions, causing environmental and economic problems. Brazil is one of the largest producers of fused, generating approximately 2 million annual WFS (ABIFA, 2012). The objective of this research is to verify the environmental and economic viability in the use of soil + WFS in layers of cover of solid waste landfills. Will be carried tests physical, chemical and mechanical characterization of a sample of WFS and soil + WFS mixtures proposed. A Technique of economic and environmental analysis will be used to evaluate these parameters. The results expected to establish the feasibility of the application of soil+WFS in layers of cover solid waste landfills studied in this research. (AU)
