摘要: 铬鞣法是目前制革工业中最成熟、产品质量最可靠、适合性最广的鞣革方法。然而,由于制革过程需要添加多种化学制剂,所排放的固废、废液、废气等会污染环境,因此,污染成为制革行业发展的最大制约因素。制革过程涉及多工段、多化料,操作复杂,科学合理地评价制革污染成了关乎制革业发展的关键问题。生命周期评价(Life cycle assessment, LCA)是一种可以量化评价一个产品从原料皮到成品革的生命周期环境影响评价方法。本文根据生命周期评价(LCA)的原理及理论框架,采用eFootprint供应链LCA网络平台,以全球变暖潜值(GWP)、一次能源消耗(PED)、酸化潜值(AP)等作为环境影响评价指标,并对铬鞣工艺的黄牛革产品加工过程的主要工序进行了全生命周期评价。这为建立制革行业LCA数据库提供参考示例,为实现我国皮革行业的绿色产业链提供数据支撑。

Abstract: Chrome tanning is currently the most mature, reliable, and suitable tanning method in leather industry. However, since the leather production needs to add a variety of chemicals, the discharge of the waste solid, liquid, and gas can pollute the environment. Therefore, pollution has become the biggest constraint for the development of leather industry. The leather production process involves multiple stages, multiple materials, and complex operations. Scientific and reasonable pollution evaluation of leather production has become a key issue related to the development of the leather industry. Life cycle assessment (LCA) is an assessment method that can quantitatively evaluate the environmental impact of a product’s life cycle from raw hide to leather. Based on the principles and theoretical framework of LCA, this paper adopted the eFootprint supply LCA network platform, global warming potential (GWP), primary energy consumption (PED), acidification potential (AP), etc. as environmental impact assessment indicators. Also, the main processes of leather production were evaluated throughout the LCA. This work provided a reference example for the establishment of the LCA database for leather industry, and gave the information support for the realization of the green industrial chain of the leather industry in China.
