One of the most challenging problems on modern urban planning and one of the goals to be solved for smart city design is that of urban waste disposal. Given urban population growth, and that the amount of waste generated by each of us citizens is also growing, the total amount of waste to be collected and treated is growing dramatically (EPA 2011), becoming one sensitive issue for local governm...

in this research, energetic andexergetic analysis of calcium oxide formation, co2 emissions, andenvironmental effects during the clinker production process in rotary kilnare investigated. first the energy and exergy analysis of rotary kiln were carried out according to the first and second law of thermodynamics based on dead state, respectively. consequently, the amount of co2 emissions associa...

The paper at first expounds two new concepts of sustainability degree and superiority degree, and founds a method of DEA of relative efficiency index to rank all decision-making-units having been identified efficient. On the basis of them, the definition and arithmetic are given to analyze them. Then seven input and output techno-innovation indexes which belong to six automobile listed companie...

A multi-criteria approach is presented for the assessment of alternative means for covering the energy needs (electricity and heat) of an industrial unit, taking into consideration sustainability aspects. The procedure is first described in general terms: proper indicators are defined; next they are grouped in order to form sub-indices, which are then used to determine the composite sustainabil...

Nike’s approach to managing supplier responsibility has greatly evolved since the 1990s, when the media uncovered claims of child labor, underpaid workers, and poor working conditions in several Asian countries. This report explores how Nike’s approach to improving social and environmental conditions in its global supply chain has evolved through integrated management of sustainability and inno...

Cryogenic machining is considered as the most sustainable alternative to conventional flood-cooled, near-dry and dry machining approaches in machining processes. This paper presents the application of a sustainability evaluation methodology for manufacturing processes, focusing on cryogenic machining processes. The methodology used here involves a metrics-based Process Sustainability Index (Pro...

in this study we analyze the effects of environmental performance on the generation of firm value from dow jones sustainability index europe. we use a sample of 122 firms from different sectors, except financial one, which belong to this index for the years 2007 through 2009. the expected results, taking into account our hypotheses, should show a positive relationship between the generation of ...

The paper presents an attempt to assess sustainability of desalination plants for water production based on resource, environmental and economic indicators. Four types of desalination plants are taken into a consideration: single MSF, dual purpose MSF, RO with local energy consumption and RO with PV electric energy production. The analysis is based on data from desalination plants in Gulf count...
