Robert “Bob” C. Boucher Jr. officially has stepped in as president and CEO of Hampton, N.H.-based Wheelabrator Technologies. Boucher succeeds Mark A. Weidman.

Weidman is retiring after 25 years with the company. Weidman will remain with Wheelabrator in a consulting role to ensure a smooth transition with the company's customers, partners and communities.

Wheelbrator, which had been a subsidiary of Waste Management, was sold to private equity firm Energy Capital Partners for $1.94 billion in a deal announced last June.

"We thank Mark for his leadership and dedicated service to Wheelabrator," board chairman and Energy Capital Partners (ECP) partner Tyler Reeder said in a statement. "He has driven a best-in-class operating culture that permeates all Wheelabrator facilities and teams. Mark also led the company's successful international expansion, leaving behind the nearly-complete, state-of-the-art Ferrybridge energy-from-waste facility and a strong development pipeline in the U.K."

Robert "Bob" C. Boucher Jr. was previously the CEO and executive director of Transpacific Industries Group Ltd., a publicly-traded waste management business in Australia. Prior to Transpacific, Boucher worked across the U.S. waste management industry for more than 20 years, serving in senior executive positions with Republic Services and Synagro Technologies and management roles with Waste Management and American Waste Systems.

"Bob's extensive waste industry experience and track record of commercial success in growing and managing large disposal businesses complements ECP's electricity and risk management focus. We look forward to partnering with him," continued Reeder.

"I am excited to be joining such a talented and entrepreneurial team,” Boucher said in a statement. “I have long respected Wheelabrator's operations and attractive asset base. The Wheelabrator team has created a leading energy-from-waste business in the U.S. and positioned the company for growth in the U.K. Together, I look forward to continuing the world-class environmental services and operations for the benefit of our customers and communities."

Wheelabrator has a platform of 16 energy-from-waste facilities, four independent power-producing facilities, four ash monofills and three waste transfer stations. Wheelabrator has an annual waste processing capacity of over 8.1 million tons, and a total combined electric generating capacity of 836 megawatts.
