Waste foundry sand. Environmental implication and characterization
Geologia USP. Série Científica, 2012 This paper presents the results of analyses using Scanning Electron Microscopy in field samples of waste foundry sand, as well as the results of granulometric, chemical and groundwater analyses. Field data allowed to characterize waste foundry sand and showed that there are elevated concentrations of metals in the groundwater (iron, manganese, boron ...

Thermal Reclamation of Foundry Sands Using Repurposed Sand Dryer Equipment
Archives of Foundry Engineering, 2018 One of the biggest problems for sand casting foundries must be the waste produced from disposable molds. Stricter environmental regulations make it harder to dispose of waste sand, so a truly competitive foundry does no longer only make great products, but also concentrates on a sustainable casting process.
