Canadian waste management firm Terrapure Environmental Ltd. is exploring an initial public offering, according to people familiar with the matter.

The Burlington, Ontario-based company is working with banks on the potential share sale, which could raise about $300 million, said the people, who asked not to be identified because the matter is private. The company could file with regulators for the IPO as early as next month.

Private equity firm Birch Hill Equity Partners Management Inc. acquired Terrapure, which was carved out of Newalta Corp., in 2015 for $300 million. In June, Terrapure acquired Envirosystems Inc. for an undisclosed sum.

Representatives for Birch Hill and Terrapure declined to comment.

Terrapure provides waste management solutions for industrial companies, including collecting and disposing of industrial waste, wastewater treatment and processing and battery recycling, according to its website.

On Wednesday, another Canadian waste management firm, GFL Environmental Inc., agreed to acquire Waste Industries USA Inc. for $3.65 billion. GFL had considered its own IPO earlier this year before BC Partners and Ontario Teachers’ Pension Plan agreed to recapitalize the company in April in a transaction that valued it at about $5.13 billion.
