Citadel buys again, this time a supplier of recyclate-based compoundsCitadel buys again, this time a supplier of recyclate-based compounds

For its sixth acquisition in just three years, Citadel Plastics Holdings Inc. chose QTR Inc., which markets custom compounds based on recycled polycarbonate and other engineering thermoplastics. QTR's brand lives on even as the company is being integrated into The Matrixx Group, another Citadel holding. QTR had annual sales of approximately $15 million, more than half out of the automotive market, and ran its compounds off of three twin-screw and to single-screw extrusion lines.
