Mitsubishi UFJ Financial Group-backed First Sentier Investors, a private equity firm, completed the acquisition of the UK division of Macquarie Infrastructure Partners-backed Wheelabrator Technologies, a waste-to-energy business in the UK and is a developer, owner, and operator of strategically located waste-to-energy facilities. Financial terms were not disclosed. “I look forward to the business continuing to execute on their strategy for continued development of critical waste infrastructure in the UK with their new shareholder and partner. The buildout of the largest, pure play waste-to-energy business in the UK is the result of many years of commitment, hard work, and strong partnerships with our customers and partners, and our ability to leverage our operational excellence from the US and embed it into the UK,” Robert Boucher, Wheelabrator Technologies President & CEO.
