This component of spent foundry sand was used to form the inside shapes of the part and needed further crushing, separation, and screening before recycling. â ¢ Post-processing needed to include the removal of gen- eral refuse and other contaminates, metals, and sizing. â ¢ Green sands were used to form the external modeling lines and were ...
from the beneficial reuse of spent ferrous foundry sands. Ferrous foundry sands (or green sand molding sands) comprise 85 to 95 per-cent of the 408 150 Mg (450,000 tons) of WFS produced annually by Indiana foundries and have been found to be generally "cleaner" than waste sands resulting from chemically bonded and shell mold-ing processes.
having permit approval to use foundry sand may be obtained by calling 317/233-2711. Please note that permit conditions, which allow the use of foundry sand may vary between the landfills permitted to use foundry sand. MSWLF's not currently approved to use foundry sand must obtain a permit modification prior to any use of
In many cases, foundry sand reuses involving a single foundry or end user may not be economically or operationally feasible, particularly when transportation costs are prohibitively expensive or when individual foundries generate relatively small quantities of sand.

California allows for recycling of Non-RCRA regu-lated hazardous waste without permits or manifests if the conditions in HSC 25143.2 are complied with. The chemical composition of spent FCC fines for instance is ideal for the manufacture of Portland ce-ment clinker. Beneficial reuse of spent FCC fine
Once a foundry decides to recycle spent sand, it is recommended that the sand be managed in a way that will prevent contamination and provide a quality product to the end user so that it is more likely that foundries will be successful in finding reuse …
This information will potentially make the process of permitting more cost effective ... Economic and environmental concerns dominate the issue of recycling foundry sand. ... (reuse = refill ...
approving reuses can enhance the opportunities for safe, beneficial reuse of foundry sand. The key factor in increasing foundry sand reuse appears to be the strong support and encouragement of the state regulatory agency. This support can be seen in some states' efforts to streamline the approval process for reuse projects.
The research is applied to an Italian foundry, supported by a European project—the Green Foundry LIFE project (LIFE17 ENV/FI/000,173) introduces novel technologies for sand‐moulding systems to cut emissions, improve indoor air quality and support the circular economy through the reuse of foundry sand that is nor mally disposed in landfills.
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.

In order to bring a solution to the problem of waste foundry sand (WFS) in the foundry sector and achieve its reuse, geopolymer building material (as a cementless technology) was produced from the WFS for the first time in the literature in this study. The physical and mechanical characteristics of this material were determined. In the first part of the …
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 ...
Always try to choose materials you can reuse whenever you can. 4. Recycle. It's hard to imagine that the United States landfilled or burned the paper of 387 million trees in 2014. You and your employees can help reduce this number by recycling, and it doesn't need to be hard. Set achievable recycling goals everyone can accomplish.
reuse foundry sand and other solid wastes. Indiana statute allows for specific reuse of type III foundry sand without having to get a permit from IDEM (IC 13-19-3-7). Indiana's Solid Waste Rule (329 IAC 10-3-1) allows for other uses of spent foundry sand and other solid waste when the reuse is determined to be "legitimate."
Foundries and foundry sand recyclers should consult state regulators to ensure that planned uses are consistent with state beneficial use and waste management programs and that the chemical and physical properties of the sand meet applicable state environmental limits, engineering performance criteria and other state requirements.
