Sportswear brand PUMA says it has demonstrated that an experimental version of its classic SUEDE sneaker can be turned into compost under specific industrial conditions, capping a two-year pilot that began with 500 test pairs and culminated in a limited commercial follow-on, RE:SUEDE 2.0. The company framed the project as a real-world trial of “biological recycling” rather than a lab exercise designed to probe how circular design might work at scale.
The timeline stretches back to 2021, when PUMA built 500 pairs of the RE:SUEDE using materials selected for end-of-life processing: Zeology-tanned suede for the upper, a thermoplastic elastomer (TPE) outsole, and hemp fibers in the construction. Volunteers in Germany wore the shoes for six months to evaluate comfort and durability before PUMA collected them for controlled disposal. The experiment is part of PUMA’s “Circular Lab,” an internal program exploring circular business models and material choices.
End-of-life processing was not ordinary curbside composting. PUMA worked with Ortessa Group in the Netherlands to shred the shoes, mix them with green household waste, and compost them in a managed tunnel system with aeration and recirculated leachate to speed biological activity. The company reported that, under these tailor-made industrial conditions, the RE:SUEDEs broke down into compost. Independent trade coverage noted the sole required additional pre-processing and time, underscoring the complexity of multi-material footwear even when those materials are chosen for biodegradability.
PUMA publicly announced the outcome on November 29, 2023, emphasizing that the composting results applied under the specific parameters of its partner facility and were not a blanket claim that any RE:SUEDE would biodegrade in any compost stream. That distinction matters as brands increasingly market “compostable” or “biodegradable” products: infrastructure, contamination, and process control are decisive determinants of what actually decomposes and how quickly.
On April 22, 2024—coinciding with Earth Day—PUMA said it would bring a commercial iteration, RE:SUEDE 2.0, to market, positioning the model as a next step informed by the pilot’s material and process learnings. The company did not present RE:SUEDE 2.0 as a mass-market, toss-in-the-garden solution, but rather as a product reflecting progress on materials, design for end-of-life, and consumer return logistics. The move signals PUMA’s intent to keep iterating even as broader industry assessments highlight the persistent barriers to circular footwear, from adhesive use to disassembly labor and limited industrial composting capacity.
Why it matters: Footwear is notoriously hard to recycle because it blends foams, rubbers, textiles, metals, and adhesives. By restricting the bill of materials and trialing an industrial composting route, PUMA’s RE:SUEDE test offers a data point on one potential pathway—biological recycling—alongside mechanical recycling and disassembly-first strategies being explored elsewhere. It also exposes the practical frictions: getting worn products back, finding compatible facilities, and proving that end-of-life outputs (like compost) meet quality thresholds for secondary use.
The bottom line: RE:SUEDE doesn’t make every sneaker compostable, and PUMA’s own communications are careful to limit the claim to tailor-made industrial settings. Still, the project moves the circularity conversation beyond renderings and prototypes into measured, documented tests—with a commercial sequel to keep pressure on materials and infrastructure innovation. For now, the industry takeaway is pragmatic: design simpler, specify materials with known end-of-life routes, and pilot with real users to learn what survives wear—and what breaks down when the game is over.
