Circular Textile Days 2025

    Where traceability meets transformation

    Stitching accountability into every seam

    Step into the beating heart of textile innovation, where circularity isn’t just a concept—it’s a dynamic journey fueled by creativity, credibility, and purpose.

    At Circular Textile Days 2025, our Textile Team from Control Union Certifications—represented by the purpose-led Marilina Paz and Jeroen Bos—will join the global dialogue reshaping the future of fashion.

    Together with pioneers across the value chain, we’ll explore what it truly means to close the loop—from recycled fibers and regenerative materials to digital traceability, verified impact, and next‑gen circular business models. This isn’t about ticking boxes or following trends. This is about driving meaningful, measurable change.

    As an independent certification body with a global reach, we work alongside leading brands, suppliers, and innovators—from Europe to Asia and Latin America—to ensure that sustainability claims are backed by data, audits, and transparency. Our approach is rooted in integrity: combining technical depth, local presence, and global perspective to empower businesses in navigating the evolving landscape of textile regulations and standards.

    Marlina and Jeroen are ready to listen, learn, and spark bold conversations. We invite you to connect with us in ’s‑Hertogenbosch—to ask bigger questions, explore practical solutions, and co-create a textile system that honours both people and planet.

    Let’s stitch accountability into every seam—and weave a future we can stand behind.

    Marilina Paz
    Certifier in the Circular Textile Industry
    In an industry where “circular” and “sustainable” are often used as buzzwords, Marlina Paz works to ensure they are more than just promises. As a certifier at Control Union Certifications, she examines every layer of a product’s story—documentation, supply chain traceability, on-site practices—to determine whether initiatives truly meet rigorous circularity standards.

    “Certification helps people trust that what they’re buying or supporting is actually making a difference,” says Marlina.

    Her expertise covers:

    • Verification of sustainability and traceability claims
    • Navigating complex supply chains
    • Applying global standards in evolving markets
    • Exploring innovations like digital product passports

    Passionate about honest impact, Marlina sees every audit as part of a bigger mission: building a textile industry that is transparent, inclusive, and sustainable.

    At the event, you’ll find her at the Control Union stand ( number needs to be included) —ready to share field insights, discuss challenges, and hear how she and her colleagues are pushing the boundaries of circularity.
    Jeroen Bos
    Auditor in the Circular Textile Industry
    From Nettle Fields to Global Standards – Meet Jeroen, Auditor in the Circular Textile Industry

    When it comes to sustainability claims, Jeroen’s job is to separate fact from fiction.

    With a background that spans textile innovation—yes, he’s even helped create garments from nettle fibers—Jeroen now works at Control Union Certifications ensuring companies meet rigorous standards like GRS, RCS, and GOTS.

    His focus: safeguarding the chain of custody so certified materials truly reflect what they claim to be and assessing the operational procedures that keep sustainability both reliable and transparent.

    “Certification isn’t just a box-tick. It’s a practical tool that supports continuous improvement and helps raise public awareness about the impact of the textile industry,” says Jeroen. “It plays a role in building trust and in driving the positive changes our industry needs.”

    His expertise includes:
    • Independent auditing against leading global textile standards
    • Safeguarding supply chain integrity through chain of custody checks
    • Reviewing procedures that form the backbone of sustainability
    • Bringing a grounded view of what circularity can—and can’t—achieve

    At the event, you’ll find Jeroen at the Control Union stand—ready to share field insights, discuss the realities of circular fashion, and show how certification can be a catalyst for a more responsible textile industry.
