When John Hamilton came to the Onyx Company as a consultant in 2010, he’d been looking for the chance to do sustainable, business-driven work. He found it and turned a traditional janitorial goods company into a leading supplier of sustainable food service products. Under his leadership, Onyx has helped mainstream the sustainable packaging supply chain by educating customers on the benefits of using green products as it tailors pricing to their needs. The company credits its high staff retention rate to talented local professionals and job training programs available in its Pilsen neighborhood of Chicago.
