Abstract

Fast changes in fashion trends have stimulated customers’ buying behavior; this has increased the demand for leather products. Fulfilling this demand requires unsustainable practices of overproduction and utilization of resources leading to increased waste generation. By far, the highest percentage of waste generated in the leather product industry is from the cutting section. Since leather scraps retain most of the chemicals added in the processing stage, disposal of this waste in landfills contributes to a higher degree of environmental pollution. This paper introduces modular design techniques for the upcycling of solid leather wastes created at the cutting stage. This contributes to creating a more sustainable approach in leather product development through the reuse of waste material, reducing required resources, and avoiding waste disposal to the environment. Primary data gathered from export-oriented leather goods manufacturing industries in Ethiopia identified a percentage of waste created at the cutting stage. Further, the physical property characterization of leather scraps was carried out to determine the appropriate modular design that can reuse the highest percentage of solid waste. The project concludes that most of the solid scraps disposed of in the leather product industry are in both areas and quality useable as raw material for the manufacturing of marketable sustainable leather products.

摘要

时尚潮流的快速变化刺激了顾客的购买行为；这增加了对皮革制品的需求。满足这一需求需要不可持续的过度生产和资源利用实践，从而导致废物产生增加。迄今为止，皮革制品行业产生的废物比例最高的是裁剪部分。由于皮革废料保留了加工阶段添加的大部分化学品，因此在垃圾填埋场处理这些废物会导致更高程度的环境污染。本文介绍了在切割阶段产生的固体皮革废料的升级回收的模块化设计技术。这有助于通过再利用废料，减少所需资源，在皮革产品开发中创建更可持续的方法，并避免将废物排放到环境中。从埃塞俄比亚出口导向的皮革制品制造业收集的主要数据确定了切割阶段产生的废物的百分比。此外，还对皮革废料的物理特性进行了表征，以确定合适的模块化设计，以实现最高比例的固体废物再利用。该项目的结论是，皮革制品行业处置的大部分固体废料在领域和质量上均可用作制造适销对路的可持续皮革制品的原材料。对皮革边角料的物理特性进行了表征，以确定合适的模块化设计，以实现最高比例的固体废物再利用。该项目的结论是，皮革制品行业处理的大部分固体废料在领域和质量上都可用作制造适销对路的可持续皮革制品的原材料。对皮革废料的物理特性进行了表征，以确定适当的模块化设计，以实现最高比例的固体废物再利用。该项目的结论是，皮革制品行业处理的大部分固体废料在领域和质量上都可用作制造适销对路的可持续皮革制品的原材料。
