Cement plants are already expanding or modernizing their capabilities to introduce bulk solids into the combustion chamber. A number of cement plants are testing and/or constructing pyrolosis systems to be recycled for both fuel value as well as the silicon and aluminum present in most soils. Low organic level aqueous streams are being evaluated.

The shape of the article effects how deeply it cuts into the coating and underlying substrate. Shapes are classified according to angularity. Angular particles cut through soft coatings and rust, cleaning faster, and producing sharper anchor patterns. Rounded particles produce a more even, peened surface, good for breaking away hard brittle coatings and mill scale.
