This booklet is intended to guide those who can benefit from foundry sand reuse, both suppliers and users, by outlining what beneficial reuse of foundry sand offers, how Indiana regulators view the sand, and where to find additional resources to help individuals take
Foundry S is a jobbing foundry specializing in truck and marine diesel and gasoline engine blocks and heads together with related items, such as flywheels, manifolds, transmission cases, and clutch housings. Since heavier sections than in Foundry F are being made, test bar castings up to 4 in. diameter are cast.

289.05(4) (4) The department shall promulgate, by rule, standards for the reuse of foundry sand and other high-volume industrial waste, including high-volume industrial waste that qualifies for an exemption from regulation under s. 289.43 (8). The department shall design the rules under this subsection to allow and encourage, to the maximum ...
Committed to Foundry Sand Recycling. Waupaca Foundry's casting processes require large volumes of sand, which is continually used, reconditioned and reused. Sand shaken off of completed castings is recaptured and recycled in the process. More than 800,000 tons of sand is re-used each year. Sand that can no longer be used for creating quality ...
A number of small foundries do not reuse their sand while some reuse it. In this paper we explore how the EffSAfound a German project in collaboration with the Metal Casting Technology Station (MCTS) at the University of Johannesburg reused spent foundry sand in a small foundry. We look at economics of reuse and quality of the reusable sand.
To petition for a BUD for foundry sand, the generator or end-user must submit to DEC: (1) A description of the waste and the proposed reuse; (2) A demonstration that the management of the solid waste will not adversely affect human health and safety, the environment, and natural resources; (3) A solid waste control plan, including, but not ...

Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

The exponential rise in the production of plastic and the consequential surge in plastic waste have led the scientists and researchers look out for innovative and sustainable means to reuse/recycle the plastic waste in order to reduce its negative impact on environment. Construction material, converting waste plastic into fuel, goods, fabric and clothing are some of the …

The metal casting industry generates spent foundry sands. Foundries purchase new, sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand is continuously removed and replaced with sand.
The foundry received an energy savings rebate from Wisconsin Power & Light Co. for installing this variable frequency drive. System Effectiveness The foundry reports that 25% of the treated sand is suitable for foundry reuse in either core or floor molding while 72%, although not reusable, is nontoxic and suitable for a standard landfill.
Local and national governments and planning authorities should encourage greater use of alternatives to sand, such as crushed rock, industrial slag and waste (including copper, fly ash and foundry ...
----- • Used foundry sand is a high volume industrial waste that can be more widely reused as an alternative to landfill disposal. A brief look at three factors supports this finding: (1) foundries generate substantial volumes of used sand that is non-hazardous, consistent in composition, and available in ample supply; (2) foundry sand exhibits physical and engineering characteristics ...

2.6 Foundry Moulding Sand - The term may include high silica sand, natural moulding sand, synthetic moulding sand imixtures and reclaimed sand placed in heaps on the foundry floor for reuse. 2.7 Sub-lot - The quantity of sand in each of the groups into which a lot or a bed of sand …
The objects of this study were to use waste foundry sand (WFS) to manufacture reclaimed resource tiles and to determine the effects of different kiln temperatures on the properties of the reclaimed WFS tiles. In this study, clay was replaced with 0 or 15 % WFS to manufacture tile specimens. Four different kiln temperatures (1000, 1050, 1100, and 1150 °C) were used in this study …
The foundry produces nearly 200,000 tons of usable sand annually, as well as approximately 35,000 tons of cupola slag, which is being recycled. Environmental Manager Larry Bowers describes the success of his program in the following way: "We now reuse over 95% of our solid byproducts with an annual savings of more than $5 million."
problem in foundries (Twarog, 1992). Molding and core sand make up 66-88% of the total waste from ferrous foundries (USEPA, 1992). b. Sand waste Green foundry sand is routinely reused. After the sand is removed from the metal piece, it can easily be remolded. However, sand fines develop with reuse.

Because spent foundry sand is composed primarily of natural materials (chemical binders added to the sand essentially are burned off during the molten metal pour), it is well-suited for beneficial reuse. Some of the spent sand can be reclaimed and reused within the foundry. The rest must be shipped of offsite for beneficial use or disposal.
Discussion of the end market demand for the spent foundry sand. Spent foundry sand is a viable and economically beneficial material which will be used in the construction industry. 5. Discussion of how spent foundry sand reuse/recycling will not be detrimental to the environment. Recycling and reuse of spent foundry sand will prevent these ...
FOUNDRY SAND WASTE. Foundries create metal castings for use in the automotive, art, construction, agriculture, and mining industries. In this process, molten metal is poured into a mold, usually made from sand or ceramics. As castings are created, the sand has to be removed and replaced due to abrasion from the high heat and mechanical stress.
The aim of this study is to identify the potential re-use of Waste Foundry Sand as an alternative material to fine aggregate in concrete, to reduce the depletion of natural resources. The performance of concrete prepared with seven different percentages (10%, 20%, 30%, 40%, 50%, 75% and ) of waste Foundry Sand is investigated.
