Investigating alternative uses for Spent Foundry Sand
After an extensive literature review by TransFIRe researchers, a number of potential applications for re-using huge quantities of Spent Foundry Sand (SFS) have been identified. As part of Work Stream 2 of the TransFIRe project, which focusses on creating new materials and process opportunities for the foundation industries, TransFIRe researchers have been undertaking a case study focussing on potential uses of Spent Foundry Sand (SFS), a waste product of UK metals foundries leftover after the production of sand moulds or cores for casting of metals. A literature review, carried out with input from the Cast Metals Federation, John Winter Ltd and Wm Lee Ltd, was undertaken to identify potential opportunities for re-using SFS and several applications were identified within ceramics, glass, cement, fillers in concrete and asphalt; and several others. Although SFS can be successfully recycled and used numerous times, the sand grains eventually degrade and their ability to [...]
