Foundry-Sand-Recycling | Waupaca Foundry

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 iron castings does not have to end up

Recycling Sand from Foundry Casting Molds

The flowsheet shown in this study is particularly adapted to the requirements of the average foundry to reclaim foundry sand for re-use. Any foundry whose new sand delivered costs is too high should seriously consider reclamation with the flowsheet as illustrated. This reclaimed sand is usually equal to, or better than the original sand. Foundry sand once used must be thoroughly water scrubbed

Beneficial Uses of Spent Foundry Sands | Sustainable

The spent foundry sand is either recycled in non-foundry applications or landfilled. In 2007, the American Foundry Society estimated Exit that less than 30 percent of the 10 million tons of spent foundry sands generated annually are recycled. EPA believes a greater percentage of spent foundry sand can be safely and economically reused.

Introduction to Foundry Sand | American Foundry Society

In modern foundry practice, sand is typically recycled and reused through many production cycles. Industry estimates are that approximately 100 million tons of sand are used in production annually. Of that, four (4) to seven (7) million tons are discarded annually and are available to be recycled into other products and industries.
