Designing for the Toughest Critics: How PADNOS, Haworth, and Royal Technologies Built an Award-Winning Benchmark for Circularity

How can manufacturers build a successful closed-loop process for consumer products that meet strict quality standards? Many companies choose to collaborate – one example is the joint project between Haworth, PADNOS, and Royal Technologies for the Fern office chair. A recent wave of accolades for Haworth’s Fern chair marks a true success story at PADNOS that directly validates the closed-loop manufacturing process we built with our partners in 2025.

Over the past year, the Fern has consistently swept major design, business, and performance circuits, proving that circular manufacturing can hold its own against keen-eyed industry critics:

Whether judged by global design panels or consumer gear reviewers, the consensus is clear: sustainable materials can meet the highest engineering and aesthetic standards in the world, entirely without compromise. The lineup of awards also signals a permanent shift in manufacturing, emphasizing sustainability as a core requirement for award-winning product design.


The Engineering Challenge

Let’s take a look behind the scenes. Haworth came to us with a bold mission: take the Fern chair – already an industry benchmark for ergonomic design – and transition its major components to a circular model.

A project like this usually hits a wall at the sourcing phase. Recycled plastics are famously unpredictable while injection molding requires absolute consistency. A minor variance in the polymer can ruin a production run.

To solve this, we combined our strengths:

  • PADNOS took charge of the materials science, sourcing and formulating post-industrial and post-consumer plastics into a high-spec, consistent resin.
  • Royal Technologies brought their advanced injection molding expertise to the table, ensuring the recycled polymers behaved perfectly under pressure.
  • Haworth integrated these components seamlessly into the final chair, preserving the exact feel and performance users expect from a premium product.

By managing the loop from raw scrap back to the factory floor, we proved that circular supply chains can deliver the exact same reliability as virgin materials.


Let’s Build Your Closed-Loop Strategy

The success of the Fern chair is a blueprint for what is possible when manufacturers stop viewing scrap as waste and start viewing it as a resource. The same circular principles apply whether you are building consumer electronics, packaging, or industrial equipment.

At its core, closed-loop manufacturing matters because the traditional “take-make-waste” model is no longer economically or environmentally viable. Relying solely on virgin materials exposes your supply chain to volatile commodity pricing and mounting regulatory pressures, all while burying valuable, high-grade polymers in landfills. A circular approach completely flips that script. By treating production scrap and end-of-life products as valuable raw materials rather than liabilities, manufacturers can drastically lower their carbon footprints, insulate themselves from raw material shortages, and satisfy a market that increasingly demands corporate responsibility.

If your company is trying to figure out how to meet sustainability targets, reduce your reliance on virgin plastics, or redesign a legacy product for the circular economy, you don’t have to figure it out on your own. PADNOS provides the materials expertise, sourcing power, and technical auditing required to make closed-loop manufacturing work for your bottom line.
