Life-cycle assessment of wastewater treatment plants
… of wastewater treatment plants (WWTPs), using a life cycle assessment (LCA) approach. In previous research, the issue of global warming is often related to traditional industries with high carbon dioxide (CO2) emissions, such as power plants and transportation. However, the analyses of wastewater …

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 …

Life Cycle Assessment of a Fiberglass House in Iceland
… for around 38% of global emissions. In previous life cycle assessment (LCA) studies, the use phase was associated with the highest lifetime emissions from buildings, but more recent studies show the relative importance of the pre-use phase. The pre-use phase becomes even more significant as the …

Advanced methods of life cycle assessment for space systems
Environmental Life Cycle Assessment is increasingly being applied within the space industry to scientifically quantify environmental impacts of space missions over their entire life cycle. This technique is particularly useful in early mission design phases since adverse life cycle impacts are more …
