Designer Iris Veentjer, owner of Studio i Focus, is dedicated to innovative material research and experimental design to foster a regenerative world. Since 2018, she has created products raising awareness about environmental and social issues. The Netherlands faces significant soil subsidence and greenhouse gas emissions due to peatlands being drained for cattle grazing, which leads to plant decomposition and CO2 release. To address this, alternative agricultural methods like wetland cultivation are being explored.
A type of plant that thrives in wet conditions are cattails, the cultivation of which is currently not profitable for farmers, which is why its fibres are typically used for low-value products like insulation. Iris’s project, RietGoed, aims to develop high-quality textiles from cattails.
Iris developed a machine to mechanically extract fibers from cattails, allowing them to be processed like linen. This innovative approach can help reduce soil subsidence and emissions while creating a biocircular production process utilizing all parts of the plant.
With RietGoed, Iris aims to inspire broader adoption of sustainable practices and scale up textile production.
“Textiles made from cattails could potentially replace synthetic oil-based yarns. I aim to have the process from plant to fiber to product be fully biocircular. After multiple recyclings, textiles can return to the fields, contributing to peatland restoration,” she summarizes.




“RietGoed can be a solution to the nitrogen problem in peat meadow areas. By draining these areas, the soil sinks and nitrogen is released into the air. If we grow cattails on peat meadows in watery peat soil and make clothing from them, farmers will have the opportunity to earn money with this new crop.” – Iris Veentjer

MATERIA FUTURA – SUSTAINABLE INNOVATIONS
18. January 2026
Materia Futura is not proposing a new bio-material category, nor a finished commercial textile. What distinguishes the project is its design-led investigation into the emotional and aesthetic dimensions of bio-based materials, an area often sidelined in sustainability discourse.
THREADED PROTOCOLS – SUSTAINABLE INNOVATIONS
17. January 2026
Threaded Protocols is not a textile innovation in the commercial sense, nor a digital tool disguised as craft. What makes the work distinct is its material investigation into how computational logic originates in textile practice and what is lost when those logics are abstracted into opaque technological systems.
