项目摘要

1.Development of an evaluation methodology of environmental impact of chemical processMethodologies for (1)Integrated environmental evaluation of a chemical process, (2)Evaluation of the changes in the environment of a process, (3)Evaluation of uncertainty in the design phase, were developed to support the environmental evaluation in the early phase of chemical process design.A procedure to select items for environmental evaluation depending on the use of chemical substances in the industrial cleaning process was investigated and proposed.2.Development of a methodology to employ results of environmental evaluation in the chemical process designA detailed activity model representing a process lifecycle from material design to process design was constructed using an example of PET recycling process. Output items and mechanisms of each activity were analyzed. A support system to propose alternatives and to represent them as process models was conceptually designed.3.Development of a methodology to make decisions under multiple objectives including economics and environmentTwo methodologies to combine multiple objectives in the decision-making were developed. One is to integrate multiple objectives into one indicator by weighting, and another is to consider them independently using eco-efficiency analysis.4.Implementation of an information infrastructure for the support of process design acquiring lifecycle informationThe conceptual design of the total system which supports alternative generation, process synthesis, process design, process evaluation and decision-making was completed.As a future study, actual implementation of the information infrastructure designed in this study should be carried out.

1.化学过程环境影响评价方法的发展（1）化学过程的综合环境评价方法，（2）过程环境变化的评价方法，（3）设计阶段不确定性的评价方法为在化工工艺设计的早期阶段进行环境评价提供了支持。根据用途选择环境评价项目的程序2.开发了一种将环境评价结果应用于化工过程设计的方法以PET回收过程为例，构建了一个详细的活动模型，描述了从材料设计到工艺设计的过程生命周期。分析了每项活动的产出项目和机制。在概念上设计了一个支持系统，以提出替代方案，并将其表示为过程模型。3.开发了一种方法，以作出决策的多个目标，包括经济和环境的两种方法，联合收割机的多个目标的决策。一种是通过加权将多个目标集成到一个指标中，另一种是通过生态效率分析将多个目标独立考虑。4.支持工艺设计获取生命周期信息的信息基础设施的实现完成了支持替代生成、工艺综合、工艺设计、工艺评价和决策的整个系统的概念设计，作为未来的研究，本研究所设计的信息基础设施应得到实际实施。
