The recycled-box rally is still going strong. Prices for old corrugated containers, or OCC, have been climbing as several newly opened mills vie for old boxes to turn into new packaging. In the Southeast, prices for OCC rose 6.6% in January, according to TTOBMA, a pulp and paper consulting firm that tracks sales and prices. The hunt for old boxes has spilled into adjacent markets, pushing up the prices mills paid for OCC in the Midwest and central Canada roughly 14% last month, the firm said. [END]
