Leather industry is facing new trends on production and consumption patterns due to society concerns. Circular economy is proposing a transition from the current economic model to a more sustainable one, in which waste is designed out and resources will be reused and recycled as long as possible. In this transition, Life Cycle Assessment (LCA) is an important tool to help decision-making. In the present review, 39 English-written peer-reviewed papers related to LCA and leather have been found, 30 of which were published in the last 6 years, meaning LCA is nowadays an important subject. Papers are presented within 4 types, focused on: 1) the whole leather production process, 2) a single step in the production process (e.g, new technologies for unhairing), 3) waste treatment and recycling, and 4) life cycle thinking with ideas on long-term strategies for leather industries. As discussed in the literature review, leather industry has important challenges to address: increasing sustainability and transparency on the supply chain, and strengthening the beauty of leather. Taking up these challenges from a life cycle perspective will help leather industry flourish in the coming future.

生命周期评估和皮革生产

由于社会的关注，皮革工业在生产和消费方式上面临着新的趋势。循环经济正在提议从当前的经济模式过渡到更可持续的模式，在这种模式下，废物被设计出来，资源将被尽可能长时间地重复利用和再循环。在此过渡过程中，生命周期评估（LCA）是帮助决策的重要工具。在本次审查中，发现了39篇与LCA和皮革有关的英文同行评审论文，其中30篇是在过去6年中发表的，这意味着LCA是当今的重要主题。论文分为4种类型，重点是：1）整个皮革生产过程； 2）生产过程中的单个步骤（例如，用于脱毛的新技术），3）废物处理和回收，（4）生命周期思考，以及皮革行业长期战略的想法。正如文献综述中讨论的那样，皮革行业面临着重要的挑战：提高供应链的可持续性和透明度，以及增强皮革的美感。从生命周期的角度应对这些挑战将有助于皮革行业在未来的未来蓬勃发展。
