Interview with Frank Brouwer from Stahl: bio-based materials on the rise
Frank Brouwer, Renewable Chemistry Specialist at Stahl, spoke to our European Coatings-editor Bettina Hoffmann about the growing demand for bio-based materials and the future of sustainable coatings.
The demand of bio-based materials is growing. For which application do you see the greatest needs for materials?
Brouwer: Across various industries, there is a growing emphasis on bio-based materials as a key solution to combat climate change and plastic waste. Sectors like fashion, automotive, and packaging are leading the way in adopting sustainable alternatives, with the greatest needs for bio-based materials currently observed in the fashion industry. In traditional industries like leather and synthetics, there is a demand to maximise the bio-based content of products, while in emerging markets of advanced substrates (vegan leather), there is a significant demand for non-animal and non-plastic materials as consumers prioritise eco-friendly products. These trends are driving the need for sustainable sourcing of raw materials in the fashion sector amongst others. Additionally, the automotive industry is showing a growing interest in bio-based coatings as a way to reduce environmental impact and meet sustainability goals.
What does R&D in bio-based coatings currently focus on?
Brouwer: Research and development efforts in bio-based coatings are currently concentrated on enhancing both: sustainability and performance. A primary focus area is the utilisation of renewable materials sourced from sustainable, low carbon footprint sources to reduce the environmental impact associated with coating production. This shift we are seeing towards renewable resources aligns with the overarching goal of conserving finite resources and reducing reliance on non-renewable materials. All of these combined are leading to environmental benefits. The integration of renewable materials is driving innovation in product development and manufacturing processes within the coatings industry, including exploration of non-isocyanate routes and energy curing methods. Embracing renewables not only fosters innovation but also enhances the industry’s resilience to market fluctuations and regulatory changes, promoting a more sustainable and adaptable approach to coatings production. Stahl offers a range of bio-based products, including segregated and mass-balanced options. The mass balance approach is recognised for its cost-effectiveness and scalability in transitioning towards renewable materials, laying the groundwork for future advancements and broader market acceptance in the bio-based coatings sector.
