瓦楞纸箱生产工艺生命周期评价案例研究

通过生命周期评价(LCA)技术框架,采用生命周期影响评价末端计量方法(LIME),对瓦楞纸箱生产过程的物耗、能耗及向环境排放的计算与特征化分析,对瓦楞纸箱生产工艺进行了环境影响评价。结果表明,其所导致的环境影响主要是化石能源消耗、全球变暖、酸化和富营养化。进一步对瓦楞纸箱生产过程中制板、印刷和成箱3工序的环境影响量化指标值做对比分析,指出了各工序导致环境影响的主要原因。并在瓦楞纸箱设计、生产工艺、废气和污水处理以及噪声治理等方面,为改善瓦楞纸箱生产工艺的环境性能提出了改进建议。

Case Study of Life Cycle Assessment for Corrugated Board Box Production Technology

According to Life Cycle Assessment(LCA) framework requested,the environmental impacts of corrugated board box production processes were assessed through calculations of substance and energy consumptions,emissions to the environment and subsequent characterization.A Life Cycle Impact Assessment based on endpoint modeling(LIME) is adopted in the evaluation.The results show that the main environmental impacts caused by the corrugated board box production are fossil energy resource consume,global warming,acidif...
