The Life Cycle Assessment for Two kinds Technologies of Refused Derived Fuel Based on GaBi Software

摘要

Based on the methodology of life cycle assessment (LCA),using GaBi 4 to analyze the two technologies for preparation of refused derived fuel (RDF) product.Compared the process of traditional technology with source separation technology for RDF preparation and analyzed the energy consumption and the environmental load value for equal quantity of RDF preparation through the two technologies.After comparing and analyzing the environmental impacts of the two technologies for RDF preparation,the result of this study showed the energy consumption of traditional technology for preparing 1kg RDF was 598.0kJthe environment load values generated were:EP74.3,AP173.9,GWP1095.5,ODP51.3;while the energy consumption of source separation for preparing 1kg RDF was 413.1kJ,the environment load values generated were:EP41.8,AP106.5,GWP674.2,ODP33.1.Finally,a better way was obtained which was source separation technology for RDF preparation.
