Kurita's Big Bet on a 'Forever Chemical' Fix with Cyclopure Tech

MINNEAPOLIS, MN – April 20, 2026 – A landmark investment by global water treatment giant Kurita Water Industries is set to accelerate the battle against “forever chemicals” in U.S. water supplies. The Tokyo-based firm has deepened its partnership with Illinois-based Cyclopure Inc., securing exclusive rights to deploy a novel, plant-derived filtration technology just as stringent federal regulations create a multi-billion-dollar cleanup mandate for thousands of American communities.

The strategic move positions Kurita and Cyclopure at the forefront of a technological gold rush, fueled by the U.S. Environmental Protection Agency's (EPA) aggressive new standards for per- and polyfluoroalkyl substances (PFAS) in drinking water. By investing in Cyclopure and its DEXSORB adsorbent, Kurita is betting it has found a more effective and sustainable answer to a problem that has vexed engineers and environmentalists for years.

A Regulatory Reckoning Creates a Market Boom

The urgency behind this partnership is rooted in the EPA’s sweeping National Primary Drinking Water Regulation, finalized in 2024. For the first time, the federal government established legally enforceable limits, or Maximum Contaminant Levels (MCLs), for several of the most notorious PFAS compounds. The rules target PFOA and PFOS—once common in products like Teflon and firefighting foam—with a near-zero limit of 4.0 parts per trillion (ppt). That’s equivalent to about four drops of water in an Olympic-sized swimming pool.

The regulations sent a shockwave through the nation's water sector. Public water systems have until 2027 to complete initial monitoring and until 2029 to implement treatment solutions and comply with the new MCLs. The EPA estimates that between 6% and 10% of the country’s 66,000 public water systems will need to take action, affecting the drinking water of up to 100 million people. The financial scope is staggering, with analysts projecting the total U.S. market for PFAS treatment could exceed $100 billion over the next three decades.

This regulatory cliff has created an unprecedented demand for effective and cost-efficient remediation technologies. While the EPA has allocated nearly $1 billion through the Infrastructure Investment and Jobs Act to help with initial costs, the long-term financial burden on municipalities and industries will be immense, driving a fervent search for the best available solutions.

The Challenge with Existing Cleanup Tech

For years, the primary weapons against PFAS have been Granular Activated Carbon (GAC) and Ion Exchange (IX) resins. GAC, a porous charcoal-like material, is a well-understood and relatively inexpensive option that adsorbs long-chain PFAS like PFOA and PFOS. However, its performance drops significantly when dealing with the newer, short-chain PFAS compounds that are increasingly prevalent. Its effectiveness can also be hampered by other organic matter in the water, leading to frequent and costly media replacement.

Ion Exchange resins offer a higher-tech alternative, showing better performance against a wider range of PFAS, including short-chain variants. They often require a smaller footprint than GAC systems but can be more expensive. Both GAC and IX face a critical challenge: what to do with the spent media? Regeneration is possible but can be energy-intensive, and the disposal of the concentrated PFAS waste remains a complex environmental problem. Other methods like Reverse Osmosis (RO) are highly effective at separating PFAS but produce a concentrated brine waste stream that requires its own costly secondary treatment.

This technological gap—the need for a solution that is effective on all PFAS, is not impacted by water chemistry, and offers a sustainable end-of-life pathway—is precisely what the Kurita-Cyclopure partnership aims to fill.

A Breakthrough from Corn: The DEXSORB Difference

At the heart of the collaboration is Cyclopure’s DEXSORB technology. Unlike carbon or synthetic resins, DEXSORB is derived from beta-cyclodextrin, a donut-shaped molecule made from corn starch. This natural, plant-based origin is just the start of its unique properties. The tiny, uniform cavities of the cyclodextrin molecules are engineered to be the perfect size and shape to trap a wide variety of PFAS molecules through a hydrophobic interaction.

According to independent research, including a 2020 study led by Cornell University, this molecular-level selectivity gives DEXSORB significant advantages. It has demonstrated superior performance in capturing both long- and short-chain PFAS, a critical weakness of older technologies. Furthermore, its performance appears largely unaffected by the presence of other natural organic matter or minerals in the water, which can quickly foul GAC and IX systems. This means it can maintain its effectiveness longer, even in challenging water conditions. The material is also certified under NSF/ANSI 61, confirming it is safe for use in drinking water treatment.

The most compelling feature, however, may be its reusability. The partnership agreement includes collaboration on a new industrial-scale regeneration plant planned for Michigan. This facility will be designed to wash the captured PFAS from the spent DEXSORB media, restoring it for reuse and creating a highly concentrated PFAS waste stream that is smaller and more manageable for final destruction. This creates a circular economy for the filtration media, drastically reducing solid waste and lowering the long-term operating costs for water utilities.

A Strategic Play for U.S. and Global Leadership

For Kurita, this is more than just a new product offering; it is a strategic maneuver to establish a dominant position in the burgeoning American PFAS remediation market. By securing exclusive U.S. sales rights for industrial and certain municipal applications, Kurita America can leverage its vast engineering expertise and customer network to deploy DEXSORB-based systems at scale. The company will not only integrate the media into treatment solutions but will also help design and build the critical regeneration infrastructure in Michigan.

This move provides Kurita with a powerful, differentiated solution to offer to its clients, from industrial facilities facing discharge permits to municipal water utilities scrambling to meet the 2029 compliance deadline. By building a track record of success in the highly regulated U.S. market, the Kurita Group aims to create a blueprint for global expansion. With PFAS regulations also tightening in Europe and Japan, the partnership with Cyclopure provides a springboard for the company to export its newfound expertise and technology worldwide, turning a response to an American environmental crisis into a global business opportunity.
