Technological innovations drive progress and efficiency, but often they also bring unforeseen risks. cross-ING helps companies overcome such challenges by providing expertise in materials science, sustainable development and regulatory requirements. We help industrial companies to develop innovative solutions that are both technically and environmentally viable.
What is PFAS?
Discovered in the 1940s and popularised by their use in DuPont's Teflon, PFAS were considered a breakthrough in materials science. With properties such as resistance to heat, stains and water, they found applications in numerous industries:
Cookware: non-stick pans and other cooking utensils use PFAS to prevent food from sticking and make cleaning easier.
Textiles: Waterproof jackets and stain-resistant clothing benefit from PFAS to improve durability and wearability in adverse conditions.
Aerospace and automotive: PFAS are used in hydraulic lines, seals and gaskets due to their resistance to extreme temperatures and corrosive substances.
Ecological and health effects of PFAS
PFAS are characterised by their incredible persistence, which leads to serious ecological problems. These chemicals can remain in the environment indefinitely, contaminating soil, water and even the atmosphere. Their stability allows them to spread in ecosystems and accumulate in living organisms. This leads to increasing concentrations in wildlife and the human population, which can have far-reaching consequences:
Cancer risks: PFAS exposure has been linked to various cancers such as kidney and testicular cancer.
Developmental disorders: Exposure during pregnancy can lead to developmental delays and low birth weight.
Impairment of the immune system: PFAS can weaken the immune system and reduce resistance to disease.
Organ damage: Long-term exposure can impair liver and kidney function.
Innovations and alternatives
The search for alternatives to PFAS has fuelled innovation in various sectors:
Textiles: companies are exploring silicone-based and other fluorine-free coatings that offer water and stain resistance.
Packaging: Biodegradable polymers and cellulosic materials are being tested as replacements for PFAS in food packaging.
Fire protection: Effective fluorine-free extinguishing foams are being developed.
However, each alternative brings its own challenges, from performance to economic viability and environmental sustainability.
Challenges in the transition
The transition from PFAS to sustainable alternatives is complex:
New materials often do not achieve the same performance as PFAS, especially in critical applications such as fire protection and aviation.
The development and implementation of alternatives can be costly and place a disproportionate burden on smaller companies.
The speed at which regulations are introduced often outstrips the development of suitable alternatives, increasing the pressure on the industry.
Technological advances can also create major environmental and health challenges. The EU and Switzerland are at the forefront of efforts to reduce and ultimately eliminate the use of these chemicals. Their proactive approach serves as a model for the rest of the world.
For companies affected by PFAS regulations, cross-ING offers crucial support. Our expertise in regulatory compliance, materials science and sustainable alternatives is helping companies navigate the transition. Together we can show that it is possible to combine technological goals with environmental responsibility.
