usage of spent foundry sand

Foundry sand is a high quality silica sand used as a molding material by ferrous and non-ferrous metal casting industries. It can be reused several times in foundries but, after a certain period, cannot be used further and becomes waste material, referred to as used or spent foundry sand (UFS or SFS). The majority of spent molding sands are ...

1. Introduction. The foundry industries are greatly involved in the worldwide automotive, agro-industrial, and military markets [].Moreover, the high demand for products derived from the casting of metallic materials results in a large volume of waste, especially spent foundry sand (SFS).

The sand is reused numerous times within the foundry operation itself. However, over time the sands become unusable and are referred to as spent foundry sands. The spent foundry sands are then reused in a number of ways, including as an ingredient in potting soil and as a foundation layer in roadway construction. The risk assessment results are ...

Plans are being made to hold a workshop on use of spent foundry sand for blended topsoils. The workshop will be held in State College on September 27, 2007. The target audience will be Pennsylvania foundry industry, landscaping, nursery and composting industry, and Department of Environmental Protection representatives. ...

Spent Sands Find Practical, Commercial Use in Soil Blending. Dec. 11, 2008. Blending spent sand into "manufactured soil" is a viable business and realistic alternative for foundries. Wally Huskonen. In 1986, Kurtz Bros. Inc. responded to the need for recycling spent foundry sand at Ford Motor Co.'s Cleveland Casting Plant.

However, because the use of spent foundry sand (SFS) is currently very limited in the concrete industry, this study investigates whether SFS can successfully be used as a sand replacement material in cost-effective, green, self-consolidating concrete (SCC). In the study, SCC mixtures were developed to be even more inexpensive and ...

The spent foundry sand considered in the study is silica-based material that has become ineffective as core or molding sand due to excess heat and abrasion after several cycles of use by iron, steel, and aluminium foundries. Sands used by …

Foundry sand can be used many times before it becomes spent and cannot be rehabilitated. This sand used to go into landfill, however the reuse and recycling of it has become a point of interest. The EPA suggests that used foundry sand that has come from the molding process can safely be used in soils, both potting soil and manufactured topsoil.

The sand is reused numerous times within the foundry operation itself. However, over time the sands become unusable and are referred to as spent foundry sands, according to EPA. The spent foundry sands are then reused in a number of ways, including as an ingredient in potting soil and as a foundation layer in roadway construction.

AFS has created a Safety Data Sheet (SDS) for spent foundry sand that applies to approximately 80% of foundry sand, covering sands from iron, steel, and aluminum foundries under specific circumstances. Typically, the required risk assessment will identify these sands as non-hazardous, industrial solid waste with a broad array of acceptable downstream uses.

In the United States alone, the foundry industry discards up to 10 million tons of sand each year, offering up a plentiful potential resource to replace sand in concrete products. However, because the use of spent foundry sand (SFS) is currently very limited in the concrete industry, this study investigates whether SFS can successfully be used as a sand replacement …

Creasey Castings is a non-ferrous foundry in Sittingbourne, They contacted NISP out of concern for the rising costs associated with the disposal of their spent foundry sand which is bonded wit h a furan resin. Creasey Castings were already using and re-using the sand within d to be replaced, this spent sand was being sent to landfill.

Of the 6 to 10 million tons of spent foundry sand generated annually, less than 15 percent is recycled. (6) Additional information on the production and use of spent foundry sand in construction materials applications can be obtained from: …

The spent foundry sand considered in the study is silica-based material that has become ineffective as core or molding sand due to excess heat and abrasion after several cycles of use by iron, steel, and aluminum foundries. Sands used by leaded and non-leaded brass and bronze foundries, and spent olivine sands were not assessed.

This paper discusses the agrotechnical use of foundry waste based on spent foundry sands (SFS). The advantage of foundry waste use is its high concentration of quartz sands and its similar physical properties to soils, including good permeability and filtration rate. An important component of...

Beneficial Uses for Spent Foundry Sands. EPA's risk assessment for the beneficial uses of spent foundry sands found that that silica-based spent foundry sands produced by iron, steel and aluminum foundries can be safely reused to save energy, reduce the need to mine materials, and reduce costs for both producers and end users. EPA supports the use of silica …

Spent Foundry Sand's Second Life: OK to Use in Some Soils. Writer(s): Molly Bean. April 14, 2015. COLUMBUS, Ohio — A study by scientists at The Ohio State University played a key role in a recent public health and environmental risk assessment of reusing spent foundry sands, or SFS, in certain soil-related uses. The sands are a byproduct ...

Spent moulds are typically ground down and re-used, especially if based on one of the more expensive sand types, though it is noteworthy that the US and UK send on average 500kg and 250kg respectively of sand to landfill for every tonne of cast metal(1). Studies have shown that spent foundry sand can be re-used in concrete production(3).
