Innovative use of chrome-containing waste and jute fibre in the production of biodegradable therapeutic insoles

Abstract

This study investigates the potential of repurposing chrome-containing waste (CCW) and jute fibre (JF) into value-added products by developing a foot pressure composite (FPC). The FPC was fabricated using a leather-based composite (LBC) and evaluated for its functional, thermal, morphological, mechanical, and biodegradation properties. Plantar pressure measurements conducted on healthy individuals wearing FPC insoles revealed an enhanced pressure distribution effect on the foot. The findings indicate that FPC outperforms conventional insoles by offering improved pressure modulation and meeting the mechanical requirements essential for insole applications. Furthermore, the composite demonstrated notable biodegradability. This research highlights a sustainable and economically viable approach for converting CCW and JF into therapeutic footwear solutions, contributing to income generation, environmental protection, and waste recycling technology.
