摘要: |
应用生命周期评价法(LCA)对条斑紫菜养殖加工行业进行了全周期的碳足迹分析,明确了各环节中碳排放源的种类和数量。结果表明,100亩条斑紫菜养殖加工过程中碳排放总量为1.25×105~2.47×105 kg CO2,远高于条斑紫菜100亩养殖形成的可移出碳汇量(9.43×103 kg CO2)。基于全产业链的分析,条斑紫菜产业尚不是一个碳汇产业。养殖阶段碳排放量最大,排放源主要来自石油化工材料的大量使用。二次加工阶段碳排放量仅次于养殖阶段,排放源主要来自纸壳包装和塑料包装的大量使用。在一次加工阶段,热源的使用是影响该阶段碳排放的主要影响因素,生物质燃料是碳排放量最低的热源形式。 |

Abstract: |
In this paper, the life cycle assessment method (LCA) was used to analyze the carbon footprint of the whole cycle of Porphyra culture and processing industry. The types and extent of carbon emission sources in each link were identified. The results show that the total carbon emission in 100 mu of Porphyra cultivation and processing was 1.25×105~2.47×105 kg CO23 kg of CO2
