Can You Reuse Sand from Sand Blasting?

Sandblasting is a way to clean dirt, corrosion, paint and other coatings from a variety of surfaces including cars, boats, planes and other vehicles. A problem presented with used abrasive blast matter such as sand is that it may contain materials which were cleaned off the surface, which can be hazardous and cause contamination to the grit.

Sand cannot be reused after sandblasting for this reason, but it can be recycled into other materials such as cement or concrete if you do insist on reworking it.

Materials which can be reused however include garnet, steel shot, and glass beads. These materials can be screened and separated from the mix of dirt and shot material, in order to capture the recyclable pieces.

Issues with the management of waste streams such as used abrasive blast materials is that it goes unnoticed as a solid waste material, and the need for testing for hazardous characteristics has not been recognised. The effect of shot blasting machine manufacturer is high quality rust removal, often using glass beads fired at a high speed to remove the worst of the rust. When silica sand has been used, the waste looks very much like sand and is not easily seen as solid waste. This would then be spread around or disposed of appropriately.
