Sustainable design approach underpinned with Life Cycle Impact Assessment(LCIA) and ontology
… and to optimise product considering ecological impact is to be developed by this research. After review and comparison of popular LCIA methods and tools, the three-tier sustainable design approach considering human labour ecological impact is developed. Design optimisation with eco-constraints …

Sustainable site remediation : a life cycle assessment approach
… that itself can create environmental burdens. Life cycle assessment (LCA) was used as a tool to examine the environmental impacts associated with remediation activities. A hypothetical contaminated site with five remediation alternatives was developed for this analysis. The results of Life …

Evaluation of environmental carrying capacity and application of the sustainability target method
… The CC can be used as a reference dataset for Life Cycle Assessment (LCA) purposes and as a baseline for other environmental studies. In this research, a set of impact-oriented U.S. CC is developed for both input- and output-related impacts. CC for eight common impact categories is evaluated: …

QUALITATIVE AND QUANTITATIVE PROCEDURE FOR UNCERTAINTY ANALYSIS IN LIFE CYCLE ASSESSMENT OF WASTEWATER SOLIDS TREATMENT PROCESSES
… in the wastewater treatment processes using life cycle assessment (LCA) method, uncertainty in LCA has to be evaluated. A qualitative and quantitative procedure was constructed to deal with uncertainty for the wastewater treatment LCA studies during the inventory and analysis stages. The …

Development of mechanistic rolling resistance model for pavement life cycle assessment
… industry to achieve sustainable transportation. Life cycle assessment (LCA) quantifies the environmental impacts of a product. It has been shown that a major component of pavement LCA results from rolling resistance (RR) between vehicle-pavement interaction. This study focuses primarily on the …
