In many sectors, recycling waste foundry sand instead of materials can result in a slight decrease in the technical performances of the final products, which could still be acceptable depending on the needed application. Recycled waste sand could be used effectively as a partial or complete replacement of standard sand in suitable ...
A source of 150,000 tons of foundry sand stock near a secondary road under rehabilitation led to an investigation on the feasibility recycling of this waste within sub-base layer. The new road material has to satisfy geotechnical functions and environmental prescriptions, avoiding any important leaching of polluting elements.
The construction industry requires natural sand for many applications. The recycled sand obtained from industrial operations can also be utilized in construction activities. Many industries generate waste sand as a byproduct. The material generated from this discarded molds and cores is usually known as "used foundry sand," "waste foundry sand," or "spent …
Waste foundry sand (WFS) is the primary by-product of foundries. Due to metals present in WFS and negative public perception, this material is commonly discarded to landfill as a waste material. ... In this research, the environmental and engineering properties of WFS, obtained from a recycling facility in Melbourne, Australia, were evaluated ...
However, the use of recycled sand also presents challenges such as the management of waste produced by the sand recycling process and the need to ensure the quality of recycled sand. Therefore, it is important for the foundry industry to develop an effective strategy for the use of recycled sand that takes these challenges into account and ...
