Mechanical and thermal methods for reclamation of waste foundry sand

Journal of Environmental Management, 2021
Binder material (e.g. bentonite, polymeric resins) is used for producing molds and cores in foundries. It deactivates upon exposure to the high temperature (~1400°C) of molten metal. As a result, these binders form either loosely or strongly bound deposits on the surface of sand grains, leaving them unsuitable for further use. Disposal of Waste Foundry

Geotechnical behavior of a compacted waste foundry sand

Construction and Building Materials, 2021
Abstract Brazil produces more than 3 million tons of waste foundry sands (WFS) each year. Although this material presents characteristics that fulfill the environmental requirements to be recycled and used as a building material, the lack of information regarding its geotechnical behavior inhibits its use, mainly in applications that require good ...

Waste foundry sand used to cover organic waste in landfills

Journal of Material Cycles and Waste Management, 2021
Waste foundry sand (WFS) is a waste generated during the molding of metal parts and primarily discarded in landfills, which generates environmental and economic impacts. Studies show that this waste presents a texture suitable for the granulometric stabilization of clayey soils, enabling its use as a cover for the daily and intermediate layers of solid

Recycling of waste foundry sands

Science of The Total Environment, 1992
Abstract Waste foundry sands are industrial wastes of important quantity. Because of the partially very high contamination of these sands with polyaromatic hydrocarbons (PAH), some of them potent carcinogens, dumping of these sand in landfills without appropriate safety measures, or use in road and landscape construction is very problematic.

Physicochemical and microbiological characteristics of waste foundry sand used in landfills

Environmental Monitoring and Assessment, 2022
Biodegradation of solid waste is a process that depends on the characteristics of waste and soil, and these characteristics may create a waterproof barrier in the landfill, changing its performance. Some residues, such as waste foundry sand (WFS), whose final destination is the sanitary landfill, can create waterproofing and alter the performance of ...

[Environmental toxicity of waste foundry sand].

Huan jing ke xue= Huanjing kexue, 2014
The metal leaching characteristics and volatile organic compounds (VOCs) of five different types of waste foundry sands were analyzed with the toxicity characteristic leaching procedure (TCLP) and head space-gas chromatography (HS-GC). Microtox and soil dehydrogenase activity (DHA) tests were then used to evaluate the bio-effects of these waste sands ...

Properties of Thermoplastics Reinforced with Foundry Sand Waste

Practice Periodical of Hazardous, Toxic, and Radioactive Waste Management, 2009
Thermoplastic rejects are unrecyclable plastics that are often burned causing harmful emissions. Foundry sand waste is a hazardous waste that poses significant health risks. This paper investigates the mechanical and environmental properties of thermoplastic rejects reinforced with foundry sand waste.
