concrete is one of the most utilized construction materials in the world. nowadays, nano silicate usage due to its special property attracted considerable attention. on this basis, studying its environmental functions is an essential issue. accordingly, the behavior of normal concrete and the one with nano silicate were compared via taking advantage of life cycle assessment (lca) method in this...

There is a strong mutuality between tourism and environment via the creation of feedback mechanisms, since tourism often places adverse effects upon the quality and quantity of natural and cultural resources of the destination, leading to its qualitative and quantitative degradation. Within theEnvironmental Impacts Assessment (EIA) studies, various methods have been proposed to assess and analy...

Bio-based fuels are the most promising and ecological alternatives to fossil fuels. Sustainable technologies are being developed and applied to biofuel production in order to minimize the costs and the environmental impacts of the system. Wastes produced from ethanol plant have been concerned ethanol producers and environmental protectors due to the negative environmental impacts caused. Challe...

escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

Residential buildings consume significant amounts of energy and produce large amount of emissions and waste. However, there is a substantial potential for energy savings in this sector which needs to be evaluated over the life cycle of residential buildings. Life Cycle Assessment (LCA) methodology has been employed to study the primary energy uses and associated environmental impacts of differe...

human activities often adversely affect natural landscapes and ecosystems. natural landscapes consist of habitats, and habitat loss and fragmentation are major threats to biodiversity. environmental impact assessment (eia)as a systematic and well documented procedure to identify, describe and assess the direct and indirect effects of a developmental project in different environments does not co...

The US National Assessment of the Potential Consequences of Climate Variability and Change provides compelling arguments for serious consideration of actions and adaptive measures by countries around the world to better manage impacts on water resources, agricultural economic sustainability and environmental quality. National resource planning at this scale requires integrated impact analysis t...

Advanced nutrient removal processes, while improving the water quality of the receiving water body, can also produce indirect environmental and health impacts associated with increases in usage of energy, chemicals, and other material resources. The present study evaluated three levels of treatment for nutrient removal (N and P) using 27 representative treatment process configurations. Impacts ...

introduction determining the importance of environmental impacts is one of the main issues and concerns in the process of environmental impact assessment (eia) of projects. ecological impacts assessment is very complicated and requires estimates and anticipates of all environmental impacts and thus always associated with uncertainty. a major problem in assessment of ecological impacts is that t...

environmental impact assessment is an important approach to achieve sustainable development. this study has investigated the environmental impact of sugar beet production. in addition data envelopment analysis was applied for detecting efficient units and decrease environmental impacts. in this study final environmental index of impact category consist of global warming, acidification, eutrophi...
