AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

AbstractThe objective of the paper is to present sustainability indicators for municipal solid waste management (MSWM). Sustainability implies environmental, economic and social acceptance. The complexity of the system-in-focus requires the employment of a systems (or cybernetic) approach: Acceptance implies clear objectives, from a specific point of view (here, the viewpoint of the municipal administration is taken), over a time horizon covering at least two generations, a life-cycle considerat...

The great variety of available Solid Waste Management System (SWMS) models, along with a plethora of continuously developing technological advancements in the design and operation of the treatment facilities and collection and transport schemes, the continous updating of national (and/or European) regulations on waste management and the increased computer literacy and availability, renders the selection of a SWMS model a complex endeavor. From the view point of a municipality, the following ques...

AbstractThe Kyoto target for Romania was to reduce its carbon dioxide emissions by 8 % from the 1989 levels. The 1989 emissions werearound 260 million tones. In 2000 the net CO2 emission - some 125 million tones - were 54% of the net CO2 emission in the reference year -1989, leaving some 115 million tones as a reserve or as a tradable resource to other countries that can not met their Kyoto targets. Assuming that Romania will sell 100 millions tones of its extra quota in accordance to Article 17...

This study presents an evaluation of the catalytic performances of Fe containing clay-based catalysts for the wet hydrogen peroxide catalytic oxidation (WHPCO) of 4-chlorophenol (4-CP) aqueous wastes. The catalysts were prepared by well-established techniques, their properties being determined by DRX, BET and chemical analysis techniques. All the tests were performed on a laboratory scale set-up. The ion-exchanged clays were the most active catalysts (100 % 4-CP and 84 % COD removal for Fe-Mt) b...

Abstract The rationality of allotting the resources for investments in sustainable agriculture needs the selection of alternative projects depending on numerous factors. The decision analysis process allows the identification of one variant with the highest utility that corresponds to the exigencies of economic, social and environmental impact efficiency. The integrated approach of the objectives specific for sustainable development actually leads to the selection of the investment portfolio ...

Up to date, several methodologies and tools have been developed not only to quantify but also to assess the environmental impacts from packaging. Different criteria and indicators have been used depending on the objectives, scope and nature of the evaluation. One of the software tools developed is that one that assesses the packaging sustainability according to the Sustainable Packaging Alliance (SPA) ...

High temperature corrosion of the surfaces of heat exchange becomes a priority in the combustion of biomass with high chlorine and alkali metals, as alkali chlorides formed deposited on the surfaces of heat transfer, leading to serious consequences for them. Forms of manifestation of corrosion are numerous, the most...

The test results show that CFB-FGD with fabric filter can be run longer and stable, and its actual performance is even higher than the design parameters. Moreover, the pressure drop of fabric filter after CFB-FGD is 600~800Pa (higher than normal). The fabric filter, which contributes to the desulf...

Chromium and cadmium are heavy metals that occur naturally in the environment and especially in soils. Their toxic effect is more pronounced at high concentrations and it depends on the oxidation states. While Cr (III) is considered an essential trace element for the metabolism of living organisms, Cr (VI) has a higher mobility and is easily soluble in soils and can be leached into surface water or groundwater, and taken up by plants. That leads to a toxic and carcinogenic effect to humans via i...

Five new aryloxyalkylcarboxylic acid derivatives (diazoaminoderivatives) are studied for their thermal behavior by applying a coupled TG-FTIR technique over the (30-400 oC) range in correlation with the environmental impact of gaseous species resulting by thermal degradation. These compounds are of a particular practical significance since they show a high biological potential as agrochemicals, such as pesticides (herbicides, acaricides, fungicides, growing stimulators etc.). This is why the pap...

AbstractStudies about the adsorption behavior of Cu(II) on D151 resin were conducted. Parameters including the effects of pH,temperature, contact time and initial metal ion concentration were studied by batch methods. Results showed that the adsorptionwas strongly dependent on pH of the medium, and the maximum uptake was obtained at pH 6.90. In the batch system, the D151resin exhibited the highest Cu(II) uptake as 277.8 mg/g at 318K, calculated by the Langmuir model. The adsorption kinetics were...

Response surface methodology (RSM) was applied for the design and analysis of experiments to predict the behavior of the initial COD and the hydraulic retention time (HRT) in the bioreactor. A statistical analysis indicated that the models adequately represented the experimental data. At the optimal conditions, the ...

Recycling of solid plastic waste composed of post-consumer mixed polyolefines (polypropylene and polyethylene) was carried out by injection moulding of secondary material streams. The materials have been characterized by melt flow index (MFI), tensile, bending and impact measurements, density and differential scanning calorimetry (DSC). The sink-float technique was used to separate the polyethylene fraction, which was then blended into virgin polyethylene at different ratios and processed anew. ...

In order to characterize them several classifications and models have been elaborated. In this work for the first time the existing European EIPs are overviewed with the help of four classifications. These classifications are based on (1) the stage of the development of the area, (2) the starting point, (3) the activity of the EIP and (4) the location of the comp...

Greenhouse gas (GHG) emissions represents a global challenge and a quantitative approach is a support for decision makers. The aim of this paper is to estimate future values of GHG emissions in Europe, considering different periods of reference and through two common mathematical parameters (average annual growth rate (AAGR) and compound annual growth rate (CAGR)). Results analysis show that a reduction of GHG emissions can be reached. However, some Member States (MSs) as Ireland and Netherland...

In last years, a significant decline in soil quality has occurred due to contamination caused by anthropic activities. These lead to adverse changes in soil physical, chemical and biological attributes and drastically reduce soil fertility. There currently are no generally accepted criteria to evaluate changes in soil quality. This lack impedes the design and evaluation of meaningful soil management programs. This paper examines the principal physical, chemical and biological characteristics th...

NaA zeolite was successfully synthesised from fly ash through hydrothermal process. The synthesised NaA zeolite was modified with Li+, Ca2+ and Mg2+ through ion exchange at a temperature of 60 °C and contact times of 1 h and 4 h. In this study the crystallinity of the synthesised NaA as well as its modified (LiA, CaA and MgA) was evaluated towards CO2 adsorption capacity using temperature programmed desorption (TPD) process at low temperature (40-150°C) and high temperature (150-700°...
