We are a team of pioneers. 

We are REPEAT Materials. A young, dynamic, and energetic team of enthusiastic professionals. Together, we are dedication to create holistic products. Our goal is to reform the linear "take-make-use-dispose" pattern into the circular "recycle-use-repeat", and help make the construction industry more sustainable.


The European commission state that 80% of the product's environmental impacts are determined at the design phase. This was our ‘Aha!’ moment. Where most producers do not have sufficient incentives to make their products more circular, REPEAT Materials® was founded to contribute to a more circular building environment.

We do this by offering competitive, circular alternatives to traditional building materials, by combining traditional engineering with state-of-the-art circular manufacturing processes. The same performance at a greatly reduced environmental impact. 


We’re excited to start a dialogue, learn about you, and make something beautiful together!

Materials / R&D


My focus is on material design and technical problem solving. After a Bachelor in Aerospace Engineering at TU Delft and Master in Novel Aerospace Materials at the same university, I worked in product development for semi-prefab construction. At REPEAT Materials® I work on sustainable innovation and user-oriented development.

Sustainability Expert / Marketing


I have a strong focus on design for circular economy in the built environment area, its integration, and management. After my Bachelor Earth Science & Economics at the VU Amsterdam, Master Urban & Industrial Ecology at the Autonomous University of Barcelona, and work experience as a sustainability and marketing manager at different companies, I work with pleasure and dedication to create a fact-based approach concept for  REPEAT Materials®.
