| Summary: | Gabi and Simapro are two different product life cycle assessment software
manufactured by two different companies. The main purpose of this work is to
utilize the Gabi software to perform a life cycle assessment on two identical
brackish water reverse osmosis desalination plant that are situated in two different
countries, namely Spain and Singapore. A comparison and discussion in the results
from Gabi and Simapro will be the highlight of this report since identical studies
have been conducted by Nanyang Technological University of Singapore,
Singapore Membrane Technology Centre, research fellow; Jin Zhou using the
Simapro software.
The life cycle assessment with CML 2001 baseline is used in both software to
compare the environmental burdens from this two identical brackish water reverse
osmosis plants. The input and output values used in this project are obtained from
the research of Jin Zhou conducted on the Simapro software in 2009 while her
modeling was done in accordance to Munoz’s work in 2008.
The results from Gabi’s analysis for both countries have indicated that plant
operation stage, out of the entire product life cycle is the key contributor to
environmental burden due to the utilization of energy in the form of electricity for
the reverse osmosis process. Although the trend of plant operation as key
environmental impact contributor was similarly spotted during the studies
conducted by Jin Zhou, differences in the values of various environmental impact
categories are evident due to the availability and representation of the processes
used for construction of the plants on Gabi software. The reason to these
differences will be further elaborated in this report. |
