Hazardous waste location-routing problems are of importance due to the potential risk for nearby residents and the environment. In this paper, an improved mathematical formulation is developed based upon a multi-objective mixed integer programming approach. The model aims at assisting decision makers in selecting locations for different facilities including treatment plants, recycling plants an...

In order for fusion power to be widely accepted in the next century, it should offer advantages compared to available sources of energy. The Starlite study has examined the ability of tokamak-based power plants to compete with other energy sources. A set of top-level system requirements and goals for system economics, safety and waste disposal, and reliability and availability were established ...

the main objectives of this paper are measuring the technical efficiency of iranian thermal power plants and investigating the determinants of technical efficiency levels in these plants. stochastic nonparametric envelopment data (stoned) method applied to plant-level data over a period of thirteen years from 1999 to 2011. this is the first comprehensive analysis (to our knowledge) of technical...

Metropolitan areas are large consumers of energy and there is a growing need to broaden the urban sustainable energy diapason and increase the share of renewable and sustainable energy in overall energy consumption. This is especially important in countries such as Serbia that have limited domestic fossil fuel resources and rely on energy imports, from the environmental, financial and energy se...

The importance of trees in a challenging urban environment ABSTRACT Our cities are a challenging environment for plants due to urban specific environmental stresses like urban heat island effects altering the radiative regime. Ecosystem service provision by urban trees qualifies the uptake of urban greening as an engineering solution to climate change. Further interdisciplinary research and wid...

In a period of less than twenty years, China has become a major actor in the implementation of waste-to-energy technologies for managing municipal solid wastes (MSW); at the present time, an estimated 15% (23 million tons of MSW) are processed in over 100 WTE plants. China is also an exception to the general rule that nations with relatively low GDP per capita rely exclusively on landfilling. T...

Fusion is one of a few future power sources with the potential to be both economically acceptable and have attractive safety and environmental characteristics. In addition fusion fuel is inexhaustible, readily available, and affordable. Fusion can be an important option in the energy mix for the future because of environmental, supply, and political difficulties associated with fossil fuels and...

plants firing fuel oil produce huge quantities of fly ash as solid waste, which needs to becharacterized prior to its proper management. it is worth mentioning that the published literature lackcomprehensive information on the characteristics of such fly ash. characteristics of fuel oil fly ash producedat selected power (pp) and water desalination (dp) plants were determined. the results showed...
