GreenSpace Waste Solutions appoints chief operating officer

GreenSpace Waste Solutions, a Brantford, Ontario-based waste management and recycling company serving customers across Canada and the U.S., has announced that Liberatore (Lib) Trombetta has joined the organization as chief operating officer (COO), effective Dec. 15, 2025.

According to GreenSpace, Trombetta brings more than 30 years of leadership experience across strategy, operations, sustainability and innovation. His expertise lies in the circular economy; environmental, social and governance advancement; and regulatory compliance. Trombetta holds a master’s degree in business administration and serves on the board of directors of the Mohawk College Foundation, Hamilton, Ontario.

“What drew me to GreenSpace was the people,” Trombetta says. “This is a team that shows up for each other and for its customers. I’m excited to join a group that cares deeply about doing the right thing and isn’t afraid to think differently about waste and circularity. My goal is simple: listen, learn and help strengthen the foundation the team has already built.”

In his role as COO, Trombetta will oversee the company’s day-to-day operations, strengthen internal systems and processes and oversee GreenSpace’s growth. His focus will be on supporting the team, reinforcing operational structure and positioning the company for its next stage of expansion across Canada and the U.S.

“From the moment we met Liberatore, it was clear he was the right fit—not just because of his experience, but because of how he carries himself,” the co-founders of GreenSpace say in a statement. “He’s thoughtful, steady and approachable. He asks the right questions and genuinely cares about people. We’re a small team, and culture matters. Lib gets that.”
