Burlington, Ont.-based Terrapure Environmental Ltd. last week said it has purchased the Canadian industrial services and waste management operations of Envirosystems Inc., a private-equity-backed company based in Dartmouth.

Terms of the deal were not disclosed.

Envirosystems specializes in providing industrial and waste management services to such industry sectors as petrochemical, refinery, marine, mining, municipal, and pulp and paper. The company had more than 1,000 employees and 25 locations across Canada.

According to PE Hub Canada, Terrapure was launched in 2015 by Canadian private equity firm Birch Hill Equity Partners. It added that Envirosystems was acquired in the same year by another private equity group TorQuest Partners.

“This acquisition represents the combination of two Canadian leaders in environmental and industrial services,” said Terrapure President and CEO Todd Moser in the statement. “By welcoming the Envirosystems team to Terrapure, we are creating a more comprehensive and resourceful organization to serve our blue-chip customers across the country with a broad and diverse suite of resource recovery and environmental solutions. This makes us an undisputed leader in the Canadian market.”

Terrapure said it is working closely with the Envirosystems senior management team to finalize integration plans for the two organizations and is committed to ensuring a seamless transition for its customers, including the eventual re-branding of Envirosystems to Terrapure.

Envirosystems’ former ownership group is retaining the company’s catalyst changeout business as well as its U.S. specialty industrial services businesses, which are in the process of being rebranded as Maviro. Maviro is headquartered in Houston, Texas, and has 13 locations across the United States.
