Once a foundry decides to recycle spent sand, it is recommended that the sand be managed in a way that will prevent contamination and provide a quality product to the end user so that it is more likely that foundries will be successful in finding reuse and recycling markets for the spent sand.
RECYCLE - With all units being set recycling targets for the use of foundry sand and rap materials we aim to make a 20% saving on virgin aggregate. Working with our fuel suppliers all of our asphalt plants now use waste oil (PFO) rather than gas oil with targets set to improve burn rate and initiatives put in place such as improved burner ignition.
Recycling foundry sand. The recycling of non-hazardous, spent foundry sand can save energy, reduce the need to mine virgin materials and may reduce costs for both producers and end users of foundry sand. Recycled foundry sand typically finds use in construction applications but can also be used in the following ways

2 ABSTRACT46 47 Waste foundry sand (WFS) is the primary by-product of foundries. Due to metals present in 48 WFS and negative public perception, this material is commonly discarded to landfill as a waste 49 material. WFS can however be potentially reused as a construction material in civil engineering 50 infrastructure projects. In order to use WFS in a sustainable manner, the engineering ...
A significant portion of foundry sand is reused internally in the casting process however some wastage is generated in maintaining the appropriate properties of the sand. This wastage can also be recycled as a raw material substitute for freshly quarried sand.
FOUNDRY SAND RECYCLING. Some state and local agencies regulate the beneficial uses of recycled foundry sand. The following uses are common throughout the country. 1. Use in other Raw Materials Foundry sand can be used in the manufacturing of other raw materials, such as asphalt, bricks, cement, grout, and concrete blocks. 2.

Reclamation of sand protects our natural resources. By selective shake-out, the green and core sand fractions can be largely separated from each other in the production of core-intensive castings such as engine blocks. By separating the fractions both a high green sand quality and a high recycling rate in the core production can be achieved.
