Identification of Significant Impact of Silicon Foundry Sands Mining on LCIA
This paper presents a case study based on a LCA (Life Cycle Assessment) research program of the silicon foundry sand (SFS) due to the large quantity of produced waste foundry sand (WFS). The foundry waste is a high priority sector within the growing European foundry industry. It is necessary to understand the full life cycle of the foundry waste in order to correctly identify magnitude and type...
متن کاملAmelioration of physical strength in waste foundry green sands for reuse as a soil amendment.
To avoid increasing costs of landfill disposal, it has become increasingly important for U.S. foundries to identify beneficial reuses for the 8 to 12 million tons of waste foundry sand (WFS) generated annually. A major drawback to the reuse of some WFSs as a soil amendment is their high soil strength, under dry conditions, where root growth may be limited. Fifteen WFSs were analyzed for strengt...
متن کاملGeoenvironmental behavior of foundry sand amended mixtures for highway subbases.
The high cost of landfilling and the potential uses of waste foundry sands have prompted research into their beneficial reuse. Roadways have a high potential for large volume usage of the foundry sands. A laboratory testing program was conducted on soil-foundry sand mixtures amended with cement and lime to assess their applicability as highway subbase materials. The mixtures were compacted in t...
متن کاملSuperfund dredging restoration results in widespread regional reduction in cadmium in blue crabs.
A nickel-cadmium battery factory released about 53 tons of mostly cadmium and nickel hydroxide suspended solid waste between 1953 and 1979 into Foundry Cove, which is tidally connected to the Hudson River estuary. A major Superfund dredging cleanup in 1994-1995 removed most of the cadmium from the sediment from within Foundry Cove. Here, we demonstrate that the cleanup reduced cadmium tissue co...
متن کاملHazardous solid waste from metallurgical industries.
Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...
