PFAS Filtration Market: Growth Drivers

Growing rate of PFAS-based contamination in soil and water bodies to drive the market growth rate

The global PFAS filtration market is expected to be led by the rising rate of PFAS contamination across the globe in soil and water bodies. In a recent event, Australia encouraged increased levels of PFAS as per the national guidelines concerning the permitted limit in two dams situated in the Blue Mountains area. Forever chemicals, according to market experts, cannot be ignored as they are commonly found in the ecosystem.

For instance, PFAS can originate from cosmetic products and non-stick cookware as well. However, per and polyfluoroalkyl substances do not easily break down in the environment due to the presence of strong carbon-fluorine bonds. They can persist in the environment for a long time. Studies indicate a clear link between the accumulation of PFAS in human bodies and the risk of developing several diseases some of which can be fatal.

As the sources of PFAS-based contamination are increasing worldwide, there is an urgent need to develop new mechanisms that can tackle and reduce PFAS pollution in the environment.

Growing emphasis by regional governments to reduce PFAS contamination to fuel growth rate in the industry

Regional official bodies and governments are realizing the seriousness of PFAS contamination, leading to the agencies drawing new initiatives and efforts to dilute and prevent further impact of per- and polyfluoroalkyl substances on the ecological systems around the globe.

For instance, in April 2024, the US Environmental Protection Agency (EPA) announced a new and critical rule deeming PFOA and PFOS, two widely used PFAS, as hazardous according to the Comprehensive Environmental Response, Compensation, and Liability Act. The novel measure has led to improved accountability and transparency related to cleaning PFAS contaminants from communities.

Additionally, the agency along with the General Services Administration mandated the use of PFAS-free cleaning products for federal buildings in the US. Such government-backed initiatives are likely to work in the favor of the global PFAS filtration market in the coming years.

PFAS Filtration Market: Restraints

Lack of studies backing the long-term effectiveness of current filtration techniques to limit market expansion

The global PFAS filtration industry is expected to be restricted by the lack of sufficient real-time studies confirming the long-term effectiveness of current techniques employed by end-users.

For instance, commonly used techniques such as ion exchange resins and activated carbon, although currently effective, do not enjoy the perks of performance clarity over longer periods as per- and polyfluoroalkyl substances become more complex and difficult to manage. On the other hand, the industry currently requires more efficient filtration techniques since the current methods are inept at destroying the contaminants.

PFAS Filtration Market: Opportunities

Ongoing innovation in PFAS filtration techniques to generate new expansion possibilities

The global PFAS filtration market is projected to generate growth opportunities due to the ongoing rate of novel innovations in the market. For instance, in September 2024, scientists at the Massachusetts Institute of Technology (MIT) announced the development of a new nature-based solution for managing contamination caused by PFAS.

A recent study by the US Centers for Disease Control (CDC) confirmed that around 98% of people tested by the agency had detectable levels of PFAS in their bodies. MIT has now developed a filtration material made of natural silk and cellulose that can remove several contaminants including heavy metals and forever chemicals. In addition to this, the antimicrobial properties of the material can further help the filters from fouling.

In March 2024, MIT researchers made yet another breakthrough innovation by designing a sensor that detects small traces of PFAS chemicals in nonstick cookware, food packaging, and many other products. According to the researchers, the sensor technology is equipped to detect PFAS levels as low as 200 parts per trillion in water samples.

According to market analysis, using biological filtration solutions will be key to future growth in the industry. These techniques are likely to consist of bioremediation, biodegradation, phytoremediation, and biosorption-based solutions.

PFAS Filtration Market: Challenges

Lack of standard testing models and complex chemical properties of PFAS to challenge market revenue

The global PFAS filtration industry is projected to be challenged by the lack of standard testing models confirming the efficiency of PFAS filter techniques.

In addition to this, certain PFAS are difficult to filter due to the presence of complex chemical properties making them immune to current methods of filtration. The growing expenses associated with PFAS filtration solutions may also impact overall revenue for the industry players.
