基于LCA的典型3C家用电器产品碳足迹研究

Research on Carbon Footprint of Typical 3C Household Appliances Based on Lifecycle Assessment

基于生命周期评价(LCA)的方法,对一台典型工业产品——扫地机器人,进行了全生命周期中的温室气体(GHG)排放量化研究。包括整个生命周期内的全部碳排放,即从原材料、生产制造、运输、使用到最后的处置及再生利用5个阶段的碳排放量化研究。结合具体产品的设计流程,计划课题拟开展3个方面的研究工作:①建立扫地机器人产品全生命周期框架;②确定扫地机器人的碳足迹系统边界及核算内容;③清单分析,对扫地机器人进行碳排放量化分析。结果表明:在扫地机器人的整个生命周期中,制造加工阶段产生的碳排放最多,对扫地机器人进行设计优化时应重点关注制造加工阶段的减碳策略研究。

Based on the method of lifecycle assessment(LCA),this paper studies the greenhouse gas(GHG)emission in the whole life cycle of a typical industrial product-sweeping robot.This includes all carbon emissions in the whole life cycle,that is,the research on carbon emissions from five stages:raw materials,manufacturing,transportation,use to final disposal and recycling.Combined with the design process of specific products,this project plans to carry out research work in three aspects:①The whole life cycle framework of sweeping robot products is established;②The boundary and accounting content of the carbon footprint system of the sweeping robot are determined;③Inventory is analyzed and the carbon emission of the sweeping robot is quantitatively analyzed.The results show that in the whole life cycle of the sweeping robot,the manufacturing and processing stage produces the most carbon emissions,so the research of carbon reduction strategy should be focused in the manufacturing and processing stage when optimizing the design of the sweeping robot.
