6 terms

per- and polyfluoroalkyl substances medical

"on the destruction and remediation of per- and polyfluoroalkyl substances (PFAS), also known as"

Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals known for resisting water, grease and heat, used historically in products like nonstick cookware, firefighting foams and stain-resistant fabrics. They matter to investors because PFAS can persist in the environment and people, prompting strict regulations, cleanup costs, product liability and shifting consumer demand — like a hidden leak that can suddenly require expensive repairs and change a company’s future cash flow and reputation.

pfas medical

"different methodologies for removing PFAS from drinking water supplies and addressed issues"

PFAS are a group of human-made chemicals used in many everyday products, such as non-stick cookware, water-repellent clothing, and food packaging, because they resist heat, water, and grease. They are often called "forever chemicals" because they do not break down easily in the environment or the human body, potentially leading to health concerns. For investors, the presence of PFAS-related risks can impact companies’ reputations, legal liabilities, and future costs.

adsorbent technical

"Our FLUORO-SORB® adsorbent has a proven track record of helping municipalities"

An adsorbent is a material that captures and holds gases, liquids, or dissolved substances on its surface rather than soaking them into its bulk—think of it like a very fine, sticky sponge that works on the outside. For investors, adsorbents matter because their effectiveness and cost affect products and operations in water and air purification, chemical processing, batteries, and drug manufacturing, influencing revenue potential, regulatory compliance, and competitive advantage.

permeable reactive barrier technical

"It can be used as a flow-through filtration media, in a permeable reactive barrier, in situ"

A permeable reactive barrier is an installed underground zone filled with materials that chemically or biologically neutralize contaminants as groundwater flows through it, functioning like a buried filter that cleans polluted water in place. Investors care because it can lower long-term cleanup costs, reduce regulatory and legal risks, protect property value, and shorten remediation timelines compared with more disruptive, expensive cleanup methods.

sediment capping technical

"in situ stabilization, soil solidification, and sediment capping. FLUORO-SORB® is"

Sediment capping is a cleanup method that places a layer of clean material—like sand, gravel, or engineered mats—over contaminated mud at the bottom of rivers, lakes, or harbors to trap or isolate pollutants and prevent them from spreading. Think of it as putting a protective blanket over a stained carpet to stop the stain from spreading and reduce immediate exposure; for investors, it can lower remediation costs, shorten regulatory timelines, reduce ongoing liability and monitoring needs, and affect the value and future use of waterfront assets.

nsf/ansi/can standard 61 regulatory

"All FLUORO-SORB® adsorbent products are NSF/ANSI/CAN Standard 61-certified."

NSF/ANSI/CAN Standard 61 is a certification that tests and approves materials and products that come into contact with drinking water to ensure they do not leach harmful levels of chemicals or contaminants. For investors, it matters because certified products are more likely to meet regulatory requirements, win contracts, enter markets, and avoid costly recalls or liability—think of it as a food-safety label for plumbing and water-system parts that signals reliability and market access.

(NYSE: MTX) (“MTI”), a leading, technology-driven specialty minerals company, announced that last week CETCO, an MTI company, participated in a U.S. Environmental Protection Agency (EPA) roundtable on the destruction and remediation of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals,” in Washington, D.C.

CETCO was represented by Global Director of Water and Remediation Barry Shadrix, who was joined on a roundtable panel by EPA Administrator Lee Zeldin, U.S. Department of Health & Human Services (HHS) Secretary Robert F. Kennedy, Jr., and four other representatives from companies focused on PFAS remediation.

The roundtable discussion highlighted different methodologies for removing PFAS from drinking water supplies and addressed issues of innovation and cost effectiveness.

“It is an honor to be able to join the government and other industry leaders in this critical conversation about PFAS remediation, which impacts millions of households across the country,” said Shadrix. “Our FLUORO-SORB® adsorbent has a proven track record of helping municipalities achieve their PFAS remediation goals effectively and cost-efficiently, as it allows for lower-capital installations, low change-out frequency, and very high capacity. We are proud to be part of the solution for PFAS contamination across the United States and globally.”

CETCO’s proprietary, bentonite-based FLUORO-SORB® adsorbent technology is a proven approach to remediate PFAS in water and soil, easily fits into existing remediation efforts, and is specifically formulated to bind across the entire spectrum of PFAS. It can be used as a flow-through filtration media, in a permeable reactive barrier, in situ stabilization, soil solidification, and sediment capping.

FLUORO-SORB® is commercially available, has been installed in numerous full-scale applications, and has been vetted by leading research universities and numerous field pilot studies that determined it to be a highly effective treatment medium. All FLUORO-SORB® adsorbent products are NSF/ANSI/CAN Standard 61-certified.
