Clean Harbors Highlights Long-Term Growth Themes at Waste360/Stifel Investor Summit

Clean Harbors, Inc. (NYSE: CLH) presented at the Waste360/Stifel Investor Summit on June 10, 2026, with senior executives Michael Battles, Co-CEO, Co-President and Director, and Eric Dugas, Executive Vice President and CFO, representing the company.

The discussion focused on major industry trends that could support Clean Harbors’ business over the coming years. These included PFAS-related waste management, reshoring and onshoring of industrial activity, and the possible closure of captive disposal facilities.

Key Business Themes Discussed

Clean Harbors operates in environmental and industrial services across North America. Its business includes hazardous waste management, emergency spill response, industrial cleaning, recycling services, and used oil re-refining through its Safety-Kleen subsidiary.

During the investor session, the company’s leadership addressed how rising environmental standards and stronger industrial activity may create long-term demand for specialized waste services. Investors are watching closely because Clean Harbors serves many industries that must follow strict environmental rules.

PFAS Waste Management Remains a Major Opportunity

One of the central topics was PFAS, often called “forever chemicals.” These substances are difficult to break down and have become a major focus for regulators, manufacturers, municipalities, and environmental service providers.

For Clean Harbors, PFAS-related work may create demand for testing, transportation, treatment, and disposal solutions. As regulations become clearer, companies may need trusted partners with the right permits, facilities, and technical knowledge to handle complex waste streams safely.

Reshoring and Onshoring Could Support Industrial Demand

The summit also highlighted reshoring and onshoring. These trends refer to companies moving production back to North America or closer to domestic markets. If more factories, chemical plants, and manufacturing sites are built or expanded, they may generate more industrial and hazardous waste.

This could support demand for Clean Harbors’ field services, waste disposal network, industrial cleaning operations, and emergency response capabilities. The company’s broad footprint gives it a strong position to serve customers that need reliable environmental compliance support.

Captive Disposal Closures May Shift Volume to Third-Party Providers

Another important topic was the potential closing of captive waste facilities. Some companies operate their own internal disposal sites, but aging assets, stricter regulations, and higher compliance costs may make those facilities less attractive.

If more companies decide to shut down or reduce captive operations, waste volumes could move toward third-party providers such as Clean Harbors. This may help companies lower risk while using specialized infrastructure already designed for regulated waste handling.

Clean Harbors’ Strategic Position

Clean Harbors is positioned as a key player because it combines collection, transportation, disposal, recycling, industrial cleaning, and emergency response. This full-service model can be valuable for customers that want one provider to manage complicated environmental needs.

The company also benefits from Safety-Kleen, which plays an important role in used oil collection, re-refining, parts washers, and environmental services for commercial, industrial, and automotive customers.

Investor Takeaway

The Waste360/Stifel discussion showed that Clean Harbors is closely tied to several long-term themes in environmental services. PFAS regulation, industrial reshoring, and changes in disposal infrastructure may all support future growth.

While the company did not frame these themes as short-term guarantees, they remain important drivers for investors following the environmental services sector. Clean Harbors’ scale, technical expertise, and North American network give it a strong foundation as demand for compliant waste solutions continues to evolve.

Overall, the presentation reinforced Clean Harbors’ role as a major environmental services provider at a time when industrial customers face growing pressure to manage waste safely, responsibly, and efficiently.
