The Chemistry of Color: Why R.U.M. Only Comes in Green, Black, and Blue
Introduction
In a world of fast furniture, "choice" is often a mask for waste. At Wehlers, our color palette isn't decided by a design trend—it’s dictated by the planet. To maintain a Full Circular model, we refuse to use dyes or mixed "material cocktails" that make furniture impossible to recycle again.
Instead, we let the waste stream lead the way.
1. Fisherman’s Green: Giving the Ocean a Break
Derived from discarded maritime gear and fishing nets (Polyamide), this material represents our commitment to the sea.
-
The Origin: Post-industrial nylon collected from the North Sea.
-
The Circular Edge: By keeping the polymer pure, the Fisherman’s Green R.U.M. can be granulated and reborn as a new chair, over and over.

2. Keyboard Black: Transforming the E-Waste Crisis
Electronic waste is the fastest-growing waste stream on earth. Keyboard Black is our answer to the ABS plastic found in the technology we discard.
-
The Origin: Recycled computer keyboards and electronic housings.
-
The Circular Edge: High-impact strength and a deep, matte finish without the need for carbon-black dyes.

3. Pharma Blue: A Second Life for Medical Plastics
Through our collaboration with leaders like Novo Nordisk, we tap into high-quality medical-grade plastic (Polypropylene) that was previously destined for the incinerator.
-
The Origin: Recycled insulin pens and laboratory plastics.
-
The Circular Edge: These are some of the most durable polymers available, ensuring the R.U.M. chair lasts for decades, not years.

Why "Pure" Materials Matter for Your ESG Goals
When you specify a R.U.M. chair for your office, you aren't just buying furniture; you are participating in a transparent material loop. Because we don't mix these streams, we can offer a Buy-Back guarantee. We want the material back because we know exactly what is in it.
