We define key research questions as a stimulus to research in the area of industrial ecology. The first group of questions addresses analytical support for green engineering and environmental policy. They relate to (i) tools for green engineering, (ii) improvements in life cycle assessment, (iii) aggregation of environmental impacts, and (iv) effectiveness of a range of innovative policy approa...

ii ABSTRACT In certain types of fleet systems, the environmental impacts of fleet operation are, to some extent, a controllable function of vehicle routing and scheduling decisions. However, there has been little prior work that has considered environmental impacts in fleet vehicle routing and scheduling optimization, in particular, where the impacts were assessed systematically utilizing life-...

abstract today, due to the rapid growth of population, development of the construction industry is a necessity. all around the world, new subjects such as sustainable development, environmental pollution, conservation of resources, and reduction of co2 emission have become the most important research topics among the scientific societies. in recent years, especially after 1997, new tools were i...

Sequential ultrasound-microwave associated extraction (SUMAE) is a combination of ultrasound waves and microwaves energies in which ultrasonic extraction is used as a pretreatment. It was performed to extract essential oil from Zataria multiflora. The extraction conditions were optimized by response surface methodology (RSM) and Central Composite Design (CCD). The antioxidant and antibacterial ...

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...

2014 INTRODUCTION The significance of environmental impacts plays a key role in how agencies of the Federal government implement the National Environmental Policy Act (NEPA). 1 Section 102 of NEPA establishes a requirement that agencies include a detailed statement of the environmental impacts (environmental impact statement, or EIS) of " proposals for legislation and other major Federal action...

Policymakers are increasingly interested in the wider consequences of major sporting events, including their environmental impacts. Indeed, London 2012 included as part of its winning Olympic bid a commitment to measure and take steps to minimize the environmental impacts of the forthcoming Games. This paper demonstrates how the ‘Ecological Footprint’ has been used to measure the environmental ...

The California Environmental Protection Agency (Cal/EPA) Environmental Justice Action Plan calls for guidelines for evaluating "cumulative impacts." As a first step toward such guidelines, a screening methodology for assessing cumulative impacts in communities was developed. The method, presented here, is based on the working definition of cumulative impacts adopted by Cal/EPA: "Cumulative impa...
