Committed to Foundry Sand Recycling - Iron Castings

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.
