Abstract

IBM is evaluating the environmental burdens associated with the use of polyvinyl chloride (PVC) in major structural parts for information technology equipment. The evaluation involves developing life cycle inventories of the following four stages: (I) production of PVC from raw materials, (II) PVC compounding, (III) molding, finishing (for electromagnetic compatibility (EMC) and decorative appearance) and (IV) the end-of-life disposal options This paper presents a study of the life cycle inventories of the end-of-life disposal options of Stage IV. The work compares landfilling, incineration with heat recovery, and an experimental closed loop PVC recycling process implemented by IBM in conjunction with its cathode ray tube (CRT) recycling process. Sensitivity and scenario analyses were used to test the influence of key parameters in each disposal system. This study demonstrates the utility of life cycle assessment for decision-making on waste management alternatives and defines criteria that constitute an environmentally positive profile for a closed-loop recycling process for business machine applications.

PVC的生命周期库存:PVC监视器外壳的处置方案

IBM正在评估与在信息技术设备的主要结构部件中使用聚氯乙烯(PVC)相关的环境负担。评估包括编制以下四个阶段的生命周期清单:(I)从原材料生产PVC， (II) PVC复合，(III)成型，整理(用于电磁兼容性(EMC)和装饰外观)和(IV)寿命终止处理方案。本文介绍了第四阶段寿命终止处理方案的生命周期清单研究。该工作比较了填埋，焚烧和热回收，以及IBM与其阴极射线管(CRT)回收工艺一起实施的实验性闭环PVC回收工艺。采用敏感性分析和情景分析方法对各处理系统中关键参数的影响进行了测试。本研究展示了生命周期评估对废物管理替代方案决策的效用，并定义了构成商业机器应用闭环回收过程环境积极概况的标准。
