RPU - RE:PU Sole

RE:PU Sole

Core Strategic Objective

Establish a complete circular economy ecosystem by integrating
RPU's chemical recycling technologies and physical upcycling innovations into mass production.

Component	Recycling Method	Implementation Details
INSOLES	Chemical Recycling	REPU-POL Application Apply recycled polyol from low-temperature depolymerization to achieve both performance and sustainability
INSOLES	Physical Recycling	r-chip Integration Integrate recycled PU chips to enhance circularity and structural stability
MIDSOLES	Physical Recycling	PU Panel Upcycling Upcycle waste PU panels into midsoles through reprocessing
OUTSOLES	Chemical Recycling	REPU-POL Application Utilize low-temperature depolymerization–derived recycled polyol to deliver performance with improved sustainability

RPU Foaming Test Results

We achieved up to 20% REPU-POL application while maintaining core physical properties.
