AbstractIn Serbia, the more recent sustainable development policy faces a number of serious problems, which are emphasized by the slow pace at which post-socialist r,eforms have been performed. Environmental aspects of transition reforms have hardly been tackled so far, the copper complex in the area of Bor (Eastern Serbia) being a notable example of such a delay. In effect, the practice of a more rigorous and systematic ex ante evaluation of possible future development scenarios is at its very ...

Abstract Literature data show that in general, plastics produced through the mechanical recycling route involve less carbon dioxide emission than when produced from crude oil. A review of readily available data shows that road transport of untreated waste plastics account for a significant portion of the carbon dioxide emission generated during recycling. Therefore, much carbon dioxide emission can be saved by optimizing the logistics in the recycling of plastics. On the example of polyolefi...

Thus, it even provides the opportunity to use highly complex electronic circuits without involving a significant explosion risk within the oil industry or in power plants, but not limited to those two. In order to achieve this performance, the type of protection is based on three pillars: limiting of energy, heat and also fault tolerance. The potential failure of components, connections, and...

Analyzing and reducing the possible effects of air pollution on human health became important issues for improving the quality of life in urban areas. Particulate matters (PM) are air pollutants with a potential important impact on the health of vulnerable people (e.g., children, elderly) and non-vulnerable people as well. The level of PM air pollution is mainly influenced by the PM concentration and by parameters such as the meteorological conditions and the synergic effects of other air pol...

The manner in which individuals deal with stressful situations depends on several variables. Personality characteristics, event circumstances, preparedness of individual, personal appraisal of events, pre-existing organizational and personal stressors are all key factors. Psychological resistance to stress can be the result of spontaneous evolution, or can be developed through special training, through programs that increase the threshold beyond which functional alterations may occur, resulti...

With the rapid development of electric vehicles (EV), more and more EV batteries will intensively face the retirement. If they are treated improperly, EV batteries might pose a serious threat to human health and environment. Therefore, recycling spent EV battery is full of significance. However, the recycling system and specific policies have not be well established in China. This paper aims to evaluate several recycling subsidy policies being considered and tested in China for their influenc...

Environmental impact assessment (EIA) for waste disposal options to examine their impacts is of great importance. Rapid impact assessment matrix (RIAM) was used in this research to evaluate impacts of the four different MSW disposal scenarios in Abyaneh village which is one of the oldest villages in Iran, attracting numerous domestic and international tourists year-round. These scenarios, respectively, were open dumping (S1), sanitary landfilling (S2), composting, followed by sanitary landfil...

Soil salinization is becoming worldwide one of the most serious land degradation issues. Seawater intrusion in upper aquifers is responsible for the largest proportion of salt-affected agricultural lands in coastal areas. In this study, the impact of different irrigation strategies on the salinity of a maize cultivated field located in the coastal plain of Ravenna, Italy, was simulated with the FAO AquaCrop model. Model calibration was supported by comparison with remote-sensed and field collect...

Three scenarios for the management of Municipal Solid Waste (MSW) produced in the study area of Bari (Southern Italy) were defined and evaluated in terms of separately collected material and fate of the residual fraction. The first scenario represented the bring points MSW separate collection system in the current configuration with a collection rate approx. 40%. The second scenario considered the study area in the optimal configuration, with a percentage of separate collection > 80% obtaine...

Healthcare wastes are produced from all medical and therapeutic activities in hospitals and healthcare centres. Around 15-20% of these wastes are classified as infectious wastes that could be hazardous. Therefore, an effective approach is required for handling costs and environmental issues. In this paper, a bi-objective Mixed-Integer Linear Programming (MILP) model is presented for logistics of infectious and non-infectious wastes. The proposed bi-objective model aims to minimize network costs ...

Optimal evacuation routes are crucial to protect workers’ safety when accidental leakage of toxic gas occurs in chemical plants. However, the majority of route optimization focuses on the transport field and few on the evacuation routing optimization in chemical plants. This paper proposes a dynamic evacuation routing optimization method for chemical plants under toxic gas release scenarios. From the complete accident scenario set (CASS) built with wind fields and leakage sources, the leak...
