#Neuralnetwork finds an #enzyme that can break down #polyurethane
A completely new enzyme that researchers developed to break down polyurethane, the #polymer commonly used to make #foam cushioning, among other things. The new enzyme is compatible with an industrial-style recycling process that breaks the polymer down into its basic building blocks, which can be used to form fresh polyurethane.

@hikingdude Thanks, I will. Also briefly checked some repair specialist shops websites and Vibram replacements go around 100 EUR so it’s borderline viable, similar shoes cost at least 300 nowadays.

And I learned about the “natural” decay of polyurethane foam today, definitely worth keeping in mind (avoid!) for infrequently used shoes (or other gear): https://www.safetyjogger.com/en/eu/technical/hydrolysis

Things nobody tells you at purchase... :(
