Sustainability is nowadays accepted by all stakeholders as a guiding principle for both public policy making and corporate strategies. However, the biggest challenge for most organizations remains in the real and substantial implementation of the sustainability concept. The core of the...

Sustainable consumption has been addressed from different perspectives in numerous studies. Recently, urban structure-related lifestyle issues have gained more emphasis in the research as cities search for effective strategies to reduce their 80% share of the global carbon emissions. However,...

Bio-jet fuel is increasingly being produced from feedstocks such as algae and tested in flight. As the industry adopts bio-jet fuels from various feedstocks and conversion processes, life cycle assessment (LCA) is necessary to determine whether these renewable fuels result in lower life cycle...

Environmental performance of different water recycling technologies is compared on the basis of the associated potential environmental impacts using the technique of Life Cycle Assessment (LCA). The LCA method is used here to support decision making in water recycling in terms of (1) comparison...

Various methods of solid waste treatment are available. However, due to heterogeneity characteristic of solid waste, determined the best means to manage solid waste in environmental view of point is not straightforward. In this case, solid waste management scenarios and an environmental analysis...

This work presents results of experimental and simulation study of a solar assisted pre-cooled hybrid desiccant cooling (PHDCS) system for air conditioning applications in Pakistan. Tests were conducted on a gas fired pre-cooled hybrid desiccant cooling test rig for high humidity Karachi...

Optimization approaches for PV grid-connected system (PVGCS) have focused on optimizing the technical and economic performances. The main objective of this study is thus to propose an integrated framework that manages simultaneously technical, economic and environmental criteria. Life Cycle...

A development in wind energy technology towards higher nominal power of the wind turbines is related to the shift of the turbines to better wind conditions. After the shift from onshore to offshore areas, there has been an effort to move further from the sea coast to the deep water areas, which...

Life cycle assessment of greenhouse gas emissions associated with biofuels should not only consider fossil fuel inputs, but also N2O emissions and changes in carbon stocks of (agro) ecosystems linked to the cultivation of biofuel crops. When this is done, current plant oils such as European...

As the production of biofuels continues to expand worldwide, criticism about, e.g. the energy output versus input and the competition with food has been questioned. However, biofuels have the possibility to be optimized in order to improve the environmental performance. This could be...
