The CIRCATEX-project is taking on this challenge by developing a PFAS-free, circular alternative to traditional non-stick coatings — without the use of added materials — by redesigning surfaces at the microscopic level. Through mechanical and laser texturing techniques, CIRCATEX is helping to shape the next generation of safe and sustainable product design.
The Goal: Eliminate PFAS, Maintain Performance
CIRCATEX is currently applying its innovations to two specific use cases:
- The non-stick surface of frying pans, a common consumer product where food safety is paramount.
- The stainless-steel glide surface of skis, where friction and durability are critical.
In both cases, the project seeks to replace PFAS-based coatings and waxes with a mechanical solution — that is, one that alters the texture of the surface itself, instead of applying chemical treatments.
This approach not only reduces environmental impact but also fits perfectly within the principles of the circular economy: fewer added materials, less waste, and longer product life.
Innovative Techniques: Engineering the Surface, Not the Coating
To achieve non-stick performance without chemical coatings, CIRCATEX explores advanced forms of laser surface texturing and abrasive blasting technologies. An extensive "longlist" of techniques has already been tested, including:
- LIPSS (Laser-Induced Periodic Surface Structures)
- Micro- and macro-textures
- Innovative blasting methods, such as wet blasting and Sublimotion, a highly controlled surface treatment
These treatments were applied to stainless steel samples, which were then subjected to a range of tests to measure their non-stick properties.
At Ghent University, a new test methodology was developed to measure adhesion forces, helping to identify which types of surface textures most effectively prevent sticking. These insights are now feeding into a new round of testing, where parameters are fine-tuned to optimise performance.
Importantly, none of these processes involves adding new materials to the product. Instead, they transform the surface itself, offering a more resource-efficient and durable solution that’s easier to recycle and safer to use.
Safe and Sustainable by Design (SSbD): Built into the Process
Beyond performance, CIRCATEX places safety and sustainability at the core of its innovation strategy. From the earliest stages, a Safe and Sustainable by Design (SSbD) assessment has been launched to evaluate:
- The processes used in texturing and blasting
- The materials involved
- The overall environmental and human health impacts
This analysis is aligned with the EU’s “Do No Significant Harm” (DNSH) principle, ensuring that the solutions developed are not only effective but also future proof from a regulatory standpoint.
By embedding SSbD principles directly into the R&D process, CIRCATEX aims to deliver a solution that meets both today’s performance demands and tomorrow’s sustainability standards.
A Model for SMEs: Innovation Without Compromise
For small and medium-sized enterprises, the shift away from harmful substances like PFAS can feel overwhelming. Regulations are tightening, customers are demanding greener alternatives, and the cost of innovation can be high.
But CIRCATEX demonstrates that with the right R&D partnerships and a clear focus on circularity, it is entirely possible to develop next-generation products that are both safe and competitive.
The project shows that radical innovation doesn’t have to mean radical cost, especially when it leads to longer-lasting, safer, and easier-to-recycle products. For SMEs, this is a chance to differentiate themselves, respond to emerging market trends, and contribute meaningfully to a cleaner, safer economy.
R&D Driving the Circular Transition
At its core, CIRCATEX is a story of research and development as a driver of transformation. By investing in deep technical expertise — from laser physics to material science and product testing — the project shows how new ideas can replace outdated solutions and open the door to more sustainable design across multiple sectors.
Looking Ahead: Toward Scalable, Market-Ready Solutions
As the project progresses, CIRCATEX continues to refine its techniques and expand testing, moving closer to market-ready solutions. With continued collaboration between research institutes, manufacturers, and industry partners, the innovations developed here could soon be applied far beyond frying pans and skis — across a broad range of products where non-stick performance is essential.
For businesses ready to future-proof their products and reduce reliance on harmful substances, CIRCATEX offers not just a technology, but a mindset: rethink, reduce, and redesign with circularity and safety at the core.
