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 in a landfill. Over 70% of the sand used for making castings is recycled every year. This ‘spent’ sand finds new life in applications from road and general construction, and agricultural use to and geotechnical fill. It adds up to over 400,000 tons! It keeps the sand out of landfills and reduces the need for mining new materials.
The sand used in the casting process could be the roadbed you drive on to get to one of the plants.
