It was a sad stumble for Winger -- a Canadian who started with Alberta-based transportation giant Trimac, that launched hazardous waste company Tricil in 1973 as a joint venture with chemical company CIL (now ICI). Winger was a Tricil director when Laidlaw Inc. bought the company in May 1991, and was put in charge of subsidiary LES a couple of years later. He led LES in a dramatic reverse takeover of hazwaste incineration company Rollins Environmental, and grew the business to an eventual market cap of $588 million (although it carried a large $3.2-billion debt). Parent company Laidlaw Inc. (founded by famous entrepreneur Michael Degroote) had resolved to leave the environmental services industry and focus on its core transportation businesses. To further dilute its holding in LES, Laidlaw succeeded in a hostile takeover of the Elgin, Illinois-based Safety-Kleen. The purchase was bitterly contested by Philip Services Corp. (PSC).
Complicated wrangling -- which included the use of shareholder 'poison pill' agreements -- eventually drove the price up two billion dollars. Under Winger's leadership, LES -- for a time renamed Safety-Kleen -- seemed to grow rapidly, and then imploded with the securities scandal, eventually filing for Chapter 11 bankruptcy protection on June 9, 2000, amid a half-dozen class-action shareholder lawsuits.
On December 24, 2003, after two-and-a-half years under the leadership of Ronald Rittenmeyer, the company's new chair, president and CEO, the company emerged from Chapter 11 bankruptcy protection. By then, Safety-Kleen had sold the former LES chemical services division, including assumption by the purchaser of more than US$250-million in potential liabilities, and resolved a long list of problems arising out of the accounting irregularities, shareholder lawsuits, and concerns from the State of South Carolina regarding the long-term care of a major hazardous waste landfill.
