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

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 ...

Capillarity of concrete incorporating waste foundry sand

Construction and Building Materials, 2013
Abstract Currently, most of the waste foundry sand (WFS) generated in the UK and many parts of the world are sent to landfill. The rising cost of land-filling and the associated environmental problems have prompted the metal casting industry into reusing the WFS.

Waste foundry sand and its leachate characteristics

Resources, Conservation and Recycling, 2010
Abstract Solid waste management has become one of the global environmental issues, as there is continuous increase in industrial by-products and waste materials. Due to lack of land filling space and its ever increasing cost, utilization of waste material and by-products has become an attractive alternative to disposal.

Waste foundry sand in concrete: A review

Construction and Building Materials, 2017
Abstract Concrete is the most extensively used construction material in the world, second to water. Increasing rate of urbanization and industrialization has lead to over exploitation of natural resources such as river sand and gravels, which is giving rise to sustainability issues. It has now become imperative to look for alternatives of constituent

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.

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

Investigating the effect of the foundry sand and waste foundry sand on the fracture toughness of concrete

Arabian Journal of Geosciences, 2021
The use of recycled or waste materials in the composition of concrete materials is one of the most applicable solutions for compensating for the lack of initial sources. The effect of waste materials on the mechanical properties of concrete should be assessed before utilizing them in mix design of practical projects such as dam construction and ...

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.

[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 ...
