A theoretical model for life cycle inventory analysis using a disaggregated hybrid methodology by Alexander Spivak( )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

Methodologies used to calculate life cycle inventory (LCI) of the functional unit have been developed since the 1970's to include hybrids of process analysis and input-output methods. Most of the current techniques do not take into account the usage of the product and end of life product aspects, or limit such applications (e.g. Method V of Tiered Hybrid LCI). The goal of this dissertation is to introduce a comprehensive method that takes strong consideration of inventory costs of use and end of life of the functional unit by combining manufacturing and de-manufacturing into the centerpiece of the hybrid analysis. In order to obtain this goal, a new disaggregated methodology is constructed by enhancing currently developed hybrid methods of life cycle inventory compilations. The new methodology is then compared to existing methodologies and to ISO14040 standards. The results of the sample calculations have shown that under right conditions use of disaggregated method will result in significant changes (lowest experimental result: 17% change in CO 2 equivalent). The theoretical comparison of ISO14040 requirements had proved that disaggregated hybrid is at least as good on some areas and better in other areas then currently accepted hybrid methods
