Igneo acquires two U.S. based businesses to form new medical waste management platform
All Press releasesNew York, 14 July 2026: Igneo Infrastructure Partners (Igneo), a global infrastructure investment manager with US$24.5 billion* has today announced the acquisition of two medical waste management businesses, Cyntox Biohazard Solutions (Cyntox) and AdvoWaste Medical Services (AdvoWaste).
The transactions support Igneo’s North American strategy, representing strategic entry into a regulated medical waste management platform with integration across collection, treatment and disposal.
Cyntox and AdvoWaste operate complementary medical waste management businesses across the United States with notable overlap across the Central, Midwest and Northeast regions. They present opportunities to expand across the medical waste value chain for small and medium quantity waste generators such as physician offices, clinics, veterinary clinics, nursing homes and ambulatory care centers.
Igneo has appointed a management team for the new platform, including Loan Mansy as Chief Executive Officer, and Bill Massa as Executive Chair, who both have deep expertise in medical and hazardous waste and environmental services.
John Ma, Partner and Co-Head North America at Igneo said: “These initial acquisitions, together with an experienced management team, present a compelling opportunity to build a scaled medical waste management business within a waste sub-sector that is underpinned by strong end-market demand, strict compliance and regulatory requirements, and supported by favourable long-term demographic and healthcare trends.”
Loan Mansy, Chief Executive Officer of the new platform said: “These two quality businesses and the broader sector present significant opportunities and I am excited to partner with Igneo to build a business focused on customers and meeting the evolving needs of the healthcare and related industries.”
