Blasting grit is an industrial abrasive used to shape, cut, sharpen, or finish a variety of other surfaces and materials. Abrasives are used in many industries, including construction, automotive, and landscaping and can be fashioned for use on metals, ceramics, carbides, composites, glass, and plastics.
Recommended Recovered Materials

EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing blasting grit as shown in the table below.
|Material||Postconsumer Content (%)||Total Recovered Materials Content (%)|
|Copper and Nickel Slag||--||100|
|Fused Alumina Oxide||100||100|
šThe recommended recovered materials content levels for steel in this table reflect the fact that the designated item may contain steel manufactured in either a Basic Oxygen Furnace (BOF) or an Electric Arc Furnace (EAF), or a combination of both. Steel from the BOF process contains 25% - 30% total recovered steel, of which 16% is postconsumer. Steel from the EAF process contains 100% total recovered steel, of which 67% is postconsumer. According to industry sources, blasting grit containing a combination of BOF and EAF steel would contain 25% - 85% total recovered steel, of which 16% - 67% would be postconsumer. Since there is no way of knowing which type of steel was used in the manufacture of the item, the postconsumer and total recovered material content ranges in this table encompass the whole range of possibilities, i.e., the use of EAF steel only, BOF steel only, or a combination of the two.
EPA did not find any specifications that would preclude the use of recovered materials in blasting grit. EPA recommends that procuring agencies exercise OSHA or other required standard safety practices when using blasting grit, particularly when using blasting grit containing slag materials.
