基于简化LCA与工艺板块理论的制革工艺生态问题的识别与评价

Identification and evaluation of ecological problems in leather-making process based on simplified LCA and plate theory

为了评价制革工艺或皮革产品的生态性能,识别其生态问题,提出了一种基于简化生命周期评价(life cycle assessment,LCA)与板块理论的制革工艺生态问题的识别与评价方法。应用板块理论,将制革工艺按功能分为若干板块,应用简化LCA进行生命周期评价,并结合价值工程进行生态问题识别。研究结果表明,将制革工艺分为鞣前准备工艺板块、鞣制工艺板块、湿态染整工艺板块和干态整饰工艺板块,应用LCA后,发现对生态性能影响的大小次序为鞣前准备工艺板块、湿态染整板块、鞣制板块和干态整饰板块,结合工程价值理论,可分析出亟待解决的生态问题入手点。

To evaluate the ecological performance of tanning process or leather products and identify ecological problems,a method for identifying and evaluating ecological problems of tanning process based on simplified life cycle assessment(LCA)and plate theory was proposed.Based on the plate theory,the leather-making process is divided into several plates according to its function,the simplified LCA is used for ecological assessment,and combined with value engineering,the ecological problem is identified.The research results show tanning process is divided into pre tanning preparation process,tanning process,wet dyeing and finishing process and dry finishing process.After applying LCA,it is found that the order of impact on ecological performance is pre-tanning preparation,wet dyeing-finishing plate,tanning plate and drying-finishing process plate.Combined with the engineering value theory,the starting point of the unsolved ecological problems in each process plate can be analyzed.
