BASF targets circular footwear

BASF will use SIMAC 2026 in Milan to present polyurethane and thermoplastic-polyurethane concepts spanning the footwear life cycle. The portfolio includes Elastopan SpringPURe for thermoformed midsoles together with Elastollan and Infinergy solutions.

Working with Gusbi, BASF has developed an automated heat-press process for lightweight midsoles designed to combine low density, design freedom and durable comfort with almost waste-free processing. With DESMA, the company is also showing a closed-loop concept that combines PU and TPU and links mechanical and chemical recycling. Three concept shoes illustrate separation and recycling routes.

The company is also introducing Infinergy Revolution, an energy-efficient heat-press processing route for expanded TPU. The approach is intended to enable lighter components, new surface designs and improved recyclability. The broader signal is that footwear development is increasingly bringing performance, disassembly, material recovery and processing energy into the same engineering discussion.
