On this trial, 500 specifically designed Suede sneakers had been despatched to testers for six months of wear and tear, and 412 of them had been later despatched to an industrial composting facility within the Netherlands.
The footwear, made with Zeology suede, hemp padding and laces, and a hemp-cotton mix lining, had been designed to decompose beneath strict situations.

The thermoplastic elastomer (TPE-E) soles, nevertheless, took round six months to interrupt down into sufficiently small items for compost. Puma views the RE:SUEDE experiment as “profitable,” although the longer timeframe for sole decomposition deviates from normal industrial composting procedures.

The transparency goals to supply worthwhile information to friends and different stakeholders, enabling them to glean insights from the experiment and apply these classes to their respective initiatives.
Marthien van Eersel, Supervisor of Supplies & Improvements at Ortessa, emphasised the numerous studying derived from the RE:SUEDE trial. He highlighted the developments made in streamlining the commercial composting course of to accommodate objects requiring an prolonged interval to decompose absolutely.
Whereas all supplies within the RE:SUEDE can break down, the only posed a singular problem, necessitating further pre-processing and extra time within the composting tunnel for a whole breakdown.
The Re:SUEDE shoe is a part of Puma’s efforts to undertake sustainable practices and supplies, akin to zeolite-based tanning for the suede, and get rid of chrome, aldehyde, and heavy metals from the method.
