In this study, the biodegradation properties of leather treated with various finishing chemicals were evaluated in order to enhance the sustainability of leather processing. We applied advanced analytical techniques, including FT-IR, thermogravimetric analysis (TGA), and solid-state NMR spectroscopy. Leather samples treated with different polymers, resins, bio-based materials, and traditional finishing agents were subjected to a composting process under controlled conditions to measure their biodegradability. The findings revealed that bio-based polyurethane finishes and acrylic wax exhibited biodegradability, while traditional chemical finishes like isocyanate and nitrocellulose lacquer showed moderate biodegradation levels. The results indicated significant differences in the biodegradation rates and the impact on plant germination and growth. Some materials, such as black pigment, nitrocellulose lacquer and wax, were beneficial for plant growth, while others, such as polyurethane materials, had adverse effects. These results support the use of eco-friendly finishes to reduce the environmental footprint of leather production. Overall, this study underscores the importance of selecting sustainable finishing chemicals to promote eco-friendly leather-manufacturing practices.
在本研究中，为提高皮革加工的可持续性，对用各种涂饰化学品处理过的皮革的生物降解性能进行了评估。我们应用了先进的分析技术，包括傅里叶变换红外光谱（FT-IR）、热重分析（TGA）和固态核磁共振光谱。用不同聚合物、树脂、生物基材料和传统涂饰剂处理过的皮革样品在受控条件下进行堆肥处理，以测量其生物降解性。研究结果表明，生物基聚氨酯涂饰剂和丙烯酸蜡具有生物降解性，而异氰酸酯和硝化纤维素漆等传统化学涂饰剂显示出中等程度的生物降解水平。结果表明，生物降解率以及对植物发芽和生长的影响存在显著差异。一些材料，如黑色颜料、硝化纤维素漆和蜡，对植物生长有益，而其他材料，如聚氨酯材料，则有不利影响。这些结果支持使用环保型涂饰剂以减少皮革生产的环境足迹。总体而言，本研究强调了选择可持续涂饰化学品以促进环保皮革制造实践的重要性。
