This thesis is part of a larger project which began in response to a request by the Spanish water agengy, Cadagua, for advice on life cycle assessment (LCA) and environmental impacts of Cadagua operated wastewater treatment plants. The project uses the LCA software GaBi and focuses on La Gavia Wastewater Treatment Plant in Madrid. This thesis analyzes three sludge management options that La Gav...

Individual countries acting alone cannot solve environmental problems that span national borders. The Global Environment Facility (GEF) was created in 1991 to serve as a mechanism for international cooperation in the funding of grants to address concerns in four areas of the global environment: biological diversity, climate change, international waters, and ozone layer depletion. To date, more ...

The reduction of environmental burdens is required to mitigate global warming, ozone layer depletion and etc. in manufacturing fields. Hence, prediction system of environmental burden for machining operation has been developed based on LCA (Life Cycle Assessment) policy in this research. The prediction system can evaluate cutting conditions from the view points of environmental burden due to el...

Methyl bromide (CH,Br) is currently the most widely used soil fumigant, and its emission into the atmosphere after application reportedly contributes to ozone depletion in the stratosphere. Irreversible degradation and partially reversible sorption reactions affect the quantity of this fumigant reaching the soil surface and escaping into the atmosphere. Incubation studies in closed headspace vi...
