In resource-intensive economies substantial quantities of secondary raw materials cannot be utilised in a closed loop because of the way their materials are engineered. Significant amounts of tin-coated copper and brass or zinc-coated steel scrap cannot be remelted directly because the coating materials disturb the cast analysis.

To facilitate a generation of high-performance secondary raw materials, PROASSORT reconditions the secondary resources by chemically removing the coating material from the base material. As a side effect, the detached coating materials can be regained and

sold as a byproduct.

Using this process creates a new product family within the commodity industry: Premium Secondary Raw Materials.
