最近在GaBi中模拟一个终端消费品的生命周期环境影响时,在废物处置阶段遇到了点困难:从使用阶段会产生一条废弃产品输出流,将进入废物处置阶段,按理说废弃处理阶段的输入流之一就是该废弃产品,PE自己的数据库里的waste treatment工艺的确是将使用阶段的废弃产品输出流作为输入项。但Ecoinvent数据库的waste treatment工艺中,却将该废弃产品作为输出流,意思仍是处理1单位该废弃产品带来的物耗能耗和污染物排放。咨询德国PE公司结果是:两者建模思路不一样。
The ecoinvent 2.2 uses another approach of modeling compared to GaBi.
Ecoinvent 2.2 : waste flows are modeled as input flows in the respective production process.
GaBi: waste wastes are modeled as output flow in the processes which reflects from my understanding more the reality.
But these are different approaches in the way of modeling, it is both not incorrect…
但未明确如何在GaBi中使用Ecoinvent数据库中的waste treatment工艺,有人能帮助解决吗?
PS:这半年课题组新招了一个助研,他想到一些问题就会写几页纸下来。导师今天明确给了我一个建议:要向他学习!
