摘要:
面对精细化环境管理需求,对产业生命周期评价方法进行了研究. 区别于产品生命周期评价,产业生命周期评价:1)功能单元的确定基于“可拆解可组合”的生态设计理念,尽可能的将其拆分成单一的产品单元或工艺单元;2)产业生命周期评价数据收集主要包括质量评估和数据整合两个过程;3)通过评价结果的不确定性分析来验证数据的合理性. 选择晶体硅太阳能电池产业进行了产业生命周期评价的案例应用,结果显示:晶体硅太阳能电池产业可分为4个产品单元和11个工艺单元. 基于上述产品单元和工艺单元的资源能源投入和污染物排放数据进行收集,在数据质量评估之后通过数据整合形成了产业生命周期数据清单. 产业生命周期环境影响主要集中在呼吸系统影响、化石燃料、致癌和气候变化四个环境影响类别;降低产业生命周期环境影响的主要途径是减少高纯多晶硅、硅片、电池片产品的电耗,组件产品中焊带消耗,硅片产品中的砂浆消耗和组件产品的铝合金边框消耗. 通过蒙特卡洛分析结果显示高纯多晶硅生命周期评价结果的不确定性较高,与数据质量评估的结果较为一致.

The Research on Industrial Life Cycle Assessment: A Case Study of Crystalline Silicon Photovoltaic Industry

Abstract:
Industrial Life Cycle Assessment (ILCA) was conducted in the face of increasingly refined environmental management requirements. ILCA was different from product life cycle assessment. The function unit of ILCA was defined as one single product or process units as far as possible based on ‘disassembly and combination’ approach. The methods of data accuracy assessment and integration into an industry-level database were established in data collection of ILCA. And the data accuracy can be verified by uncertainty analysis. Crystalline silicon photovoltaic industry was taken as a case study. The result showed that the crystalline silicon photovoltaic industry was separated into four productions and eleven units. The data of the mass and energy inputs, and the environmental emissions were collected based on above productions and units. After data accuracy assessment, the data inventory of crystalline silicon photovoltaic industry was obtained from data integration. The life cycle environmental impacts of crystalline silicon photovoltaic industry main come from respiratory, fossil fuel, carcinogen and climate change categories. Raw material reduction and energy savings are the primary pathways to decreasing the environmental impacts especially for decreasing electrical consumption in solar-grade silicon, wafer and cell productions, solder in panel production, silicon carbide in wafer production and aluminum alloy in panel production. The highest uncertainties was solar-grade silicon production in the uncertainties analysis using a Monte-Carlo simulation, while this finding was accordance with the result of data accuracy assessment in data collection.
