FULL CIRCLE LITHIUM SUCCESSFULLY EXTINGUISHES PERSISTENT C&D LANDFILL LITHIUM-ION BATTERY FIRE

Full Circle Lithium Corp. suppressed on May 18, 2026, a persistent construction and demolition landfill fire in Evans county, Georgia, believed to have been ignited by an improperly disposed lithium-ion battery. The deployment marks another significant real-world validation of FCL-X's proprietary fire suppression technology in one of the most challenging environments facing the waste management industry today.

The incident

The fire at the Evans county C&D landfill facility burned for approximately three days despite continuous suppression efforts by local fire department crews. Deep-seated combustion within the waste pile created persistent hot spots that continued to reignite beneath the surface -- a hallmark of lithium-ion-battery-driven landfill fires that conventional water- and foam-based suppression tools are ill-equipped to address.

According to Matt Roper, vice-president of Roper Environmental Services and a waste industry expert involved in the response: "Lithium-ion batteries are becoming one of the most significant fire risks facing waste facilities today. When these batteries are crushed, punctured or damaged during collection and disposal operations, they can enter thermal runaway and ignite surrounding materials. Once that happens inside a landfill or debris pile, the fire can become extremely difficult to access and extinguish. I have responded to many landfill fires, and nothing I have used compares to the effectiveness of FCL-X."

Following multiple days of unsuccessful suppression, FCL-X was deployed. The results were immediate and definitive:

• Active fire fully extinguished in under one hour;
• Remaining hot spots suppressed in fewer than two hours;
• All smouldering areas completely resolved within three hours.

"This incident is exactly why FCL-X exists. Lithium-ion-battery fires in waste environments are fundamentally different from conventional fires -- they burn hotter, reignite more readily and penetrate deeper into the waste mass than anything traditional suppression systems were designed to handle. The Evans county result demonstrates that FCL-X is not just an incremental improvement. It is a category-defining solution to an industry crisis that will only grow. We are proud to be delivering real outcomes for first responders and facility operators who have been left without adequate tools for far too long," said Chad Carver, vice-president of sales and operations at Full Circle.

A growing national challenge, with no current sector-wide solution

The Evans county incident is not an isolated event. Lithium-ion-battery fires at U.S. waste and landfill facilities have reached alarming levels for which the industry currently has no proven, scalable suppression answer.

Studies estimate that 98.3 per cent of lithium-ion batteries ultimately end up in landfills. The U.S. Environmental Protection Agency has identified disposed lithium-ion batteries as likely hazardous waste due to ignitability (D001) and reactivity (D003) characteristics, and preliminary data from its 2023-2025 monitoring program found lithium contamination in approximately 25 per cent of public water systems surveyed -- underscoring that landfill fires are not merely an operational problem but an environmental one.

The U.S. market opportunity

The scale of the unaddressed problem translates directly into a significant commercial opportunity for Full Circle. Based on publicly available industry data, the company estimates the U.S. addressable market for specialized lithium-ion-battery fire suppression solutions across the waste management sector as follows.

With over 4,100 active landfill facilities operating across the United States -- including more than 1,500 C&D debris sites and 2,600-plus municipal solid waste -- alongside hundreds of transfer stations, material recycling facilities and tens of thousands of waste collection vehicles, the scale of unprotected lithium fire exposure is substantial and growing. The waste industry currently has no sector-wide solution. Conventional water suppression, foam and dry chemical agents are largely ineffective against deep-seated lithium thermal runaway. FCL-X is purpose-built for this environment.
