Circular Design Principles: Lessons From Dutch Design Week 2026

Circular design principles are the rules designers use to keep products and materials in use and out of the waste stream: design out waste, keep things circulating at their highest value, and work with natural systems. Dutch Design Week 2026, which ended on 25 October in Eindhoven, is a good moment to restate them, because its theme R.A.W. put unfinished, experimental thinking at the centre.

Key takeaways

• Circular design principles start from three aims set out by the Ellen MacArthur Foundation: eliminate waste and pollution, circulate products and materials, and regenerate nature.
• Dutch Design Week 2026 ran from 17 to 25 October in Eindhoven under the theme R.A.W., Rebel Authentic Worth.
• The European Commission has said the Circular Economy Act is due before the end of 2026, so designers should expect more rules on recycled content and producer responsibility.
• Design decisions come first: a widely cited estimate in Commission ecodesign documents puts up to 80 per cent of a product’s environmental impact at the design stage.
• Practical circular design means disassembly, repair, single-material parts and honest information about what a product is made of.

What are the circular design principles?

The Ellen MacArthur Foundation, which has shaped the field, describes a circular economy as one driven by design with three principles: eliminate waste and pollution, circulate products and materials at their highest value, and regenerate nature. Circular design applies those aims to a specific object, building or service. It asks where the material comes from, how long the thing will be used, and what happens when the user is done with it.

Circular design is different from recycling. Recycling deals with material after it has become waste, and often at lower quality. Circular design works earlier, so that the product can be repaired, reused, remade or taken apart cleanly, and recycling is the last option rather than the first.

Why does the design stage matter so much?

Most choices that fix a product’s footprint are made before it is manufactured: the materials, the way parts are joined, the number of components and the expected life. Commission ecodesign documents have long cited an estimate that up to 80 per cent of a product’s environmental impact is determined at the design stage. It is an estimate rather than a measured figure, but it explains why regulation targets design directly.

What did Dutch Design Week 2026 show about circular design?

The week took place from 17 to 25 October 2026 across Eindhoven. According to the Dutch Design Week site, R.A.W. stands for Rebel Authentic Worth and marks a return to the core of design. In our preview of the 2026 programme we noted that the theme favours unpolished and experimental work over finished products.

That fits circular design well. Early prototypes show their materials and joints openly, which makes it easier to judge whether a part can be separated, repaired or reused. A polished surface can hide how a product is made; a raw one cannot. When you visit a festival like this, a good test is simple: ask what the object is made of, how it comes apart and where it goes next. Our 2025 recap of the previous edition offers the same questions for comparison.

Which principles are worth testing at an exhibition?

• Material choice: is the material renewable, recycled or easy to recycle, and is it a single material rather than a laminate?
• Disassembly: can a person with basic tools take the product apart without damaging it?
• Repair and upgrade: are parts standard, replaceable and documented?
• Information: does the maker say what is in the product and how to return or recycle it?

The last point is becoming a legal matter. Our explainer on the EU Digital Product Passport covers how product information is meant to travel with an item, and our report on materials at London Design Festival shows how material stories are told in practice.

What does the Circular Economy Act mean for designers?

The European Commission has said it will present a Circular Economy Act before the end of 2026. Its content was not final at the time of writing, and the date has been moving. Trade reports expect it to deal with the market for recycled raw materials and with how producers take responsibility for products at end of life, but designers should treat those details as expectations until the proposal is published.

What is already clear is the direction. The Ecodesign for Sustainable Products Regulation sets the frame for products on the EU market to be more durable, reusable and recyclable. A designer who documents material choices, avoids glued composites and plans for repair will be ready for either outcome.

How can a small studio prepare now?

Start with a short material and disassembly sheet for each project. List every material, the way each part is joined and the tool needed to separate it. That one page answers most of the questions that clients, buyers and future rules are likely to ask, and it costs very little time when done during design rather than afterwards.

Frequently asked questions

What is circular design?

Circular design is an approach that plans for a product’s materials to stay in use. It aims to eliminate waste at the source by choosing durable materials, making repair easy and allowing clean disassembly, so that recycling is a last step rather than the main plan.

What are the main circular design principles?

The three most cited are eliminating waste and pollution, circulating products and materials at their highest value, and regenerating nature. In practice, designers translate them into choices about materials, joints, repair, reuse and clear product information.

When is the EU Circular Economy Act due?

The European Commission has said it will present the act before the end of 2026. Its contents were still being settled at the start of November 2026.
