he Future of Leather Production Based on Chemicals Evaluation in Conjunction with Modern Tools for Higher Performing Processes and Lower Environmental Impact

Abstract

In response to rising pressure from both market forces and global institutions, the leather manufacturing sector is actively seeking solutions to minimize its environmental impact. This has triggered an increase in research and development with a particular focus on sustainable chemistry as the pillar for creating a more responsible and future-proof industry. Additionally, there’s a call for transparency and robust assessments of industry practices to empower customers and minimize environmental impact. This study explored the potential of bio-based chemicals in tanning, retanning, and finishing processes. It compared different tanning technologies based on their chemical composition, bio-based content, tanning procedures, and environmental impact using Life Cycle Assessment (LCA) methodology. The traditional chromium tanning process served as the benchmark, while the Olive oil Mill Wastewater technology (OMW) received particular attention due to its high bio-based content. The study concludes by comparing the effectiveness, safety, and environmental impact of different tanning technologies. It demonstrates that the OMW process, with its high bio-based content, produces high-quality leather with significantly less environmental impact compared to traditional methods.
