First-quarter earnings results are in for the U.S. waste and recycling industry, one year after the pandemic's effects began impacting their operations, and the incremental recovery continues. Multiple companies reported volumes turning positive in recent months as more local economies reopen, and say they're seeing boosts from higher recycled commodity values. M&A activity is also still active for many, especially ahead of potential tax changes under the Biden administration. Further consolidation is expected in the months to come.

Catch up on results and takeaways from Waste Management, Republic Services, Waste Connections, GFL Environmental, Covanta and Casella Waste Systems.
