Solid waste management systems assessment: the municipality's point-of-view
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 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...

Methyl tert- butyl ether occurrence and degradation in water
Environmental Engineering and Management Journal › Vol. 6 › Nr. 2 The use of gasoline oxygenated with MTBE (methyl tert-butyl ether) reduced significantly air pollution (16 - 23% lower emissions of CO and 18% lower emissions of unburned hydrocarbons) but increased water pollution. There is no European or national regulations for MTBE in drinking water except for Denmark, which has set a limit value of 30 µg/ L for MTBE. USEPA proposed a maximum concentration of 20- 40 µg/L. This paper is a review with 70 references on the MTBE production, use, properties and...

EVALUATION AND APPLICATION OF SEMI-DRY FUEL GAS DESULFURIZATION (FGD) WITH FABRIC FILTER
Environmental Engineering and Management Journal › Vol. 10 › Nr. 7 Semi-dry FGD with fabric filter has been extensively studied in recent years. After a series of industrial tests on 300MW boiler with semi-dry FGD and fabric filter, some operation notes were obtained. 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...

Environmental Engineering and Management Journal › Vol. 13 › Nr. 3 AbstractThe ever-growing demand for environmental assets is a phenomenon of our times. Calculating the value of these assets couldplay an important role in providing information about them and also contribute to their conservation and improvement. However,the intangible and subjective aspects involved in this kind of valuation make it difficult, if not impossible, to value them by thetraditional methods. This paper proposes the use of the Analytic Multicriteria Valuation Method (AMUVAM), which i...

The proposed bi-objective model aims to minimize network costs ... Autori: Mohammad Nikzamir ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28314
MODELING OF IN-SEASON WINTER WHEAT NITROGEN REQUIREMENTS USING PLANT REFLECTION INDICES
Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 A significant reduction in nitrogen (N) losses from agricultural fields will make a positive impact on the environment. Managing nitrogen for the optimum application provides economic benefits as well as environmental protection. This study presents a model
that was developed to determine the optimum ratio of N to yield based on N sensor indices in winter wheat. A quadratic polynomial model was used to characterize the relationship between N and yield for the optimum N rate. The N was applied t...

EFFECT OF THIOSULFONATE-BIOSURFACTANT COMPOSITIONS ON PLANTS GROWN IN OIL POLLUTED SOIL
Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 The work is devoted to the search and investigation of the properties of the effective environmentally friendly phytoremediation activators. An integrated approach was used to evaluate the effect of the compositions of thiosulfonates with rhamnolipid biosurfactant on remediation plants. The biochemical and biophysical analysis of the rapeseed and ryegrass plants grown in the oil polluted soil - photosynthetic pigments, indicators of oxidative reactions and electrical impedance characteristics we...

APPLICATION OF PASSIVE SAMPLERS FOR MONITORING O3 AND NO2 AND CORRELATION OF CONCENTRATION LEVELS WITH METEOROLOGICAL DATA
Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 This research applied passive air pollution samplers to monitor the concentration of the pollutants nitrogen dioxide (NO2) and ozone (O3) in order to investigate the relationships between pollutant concentrations and meteorological variables. The study was carried out in three strategic sites in the municipality of Erechim, Brazil, which provide intense traffic of small and large vehicles. The pollutant analyses were performed using the method of UV/VIS spectrophotometry. NO2 concentrations vari... Autori: Eduardo Pavan Korf ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28326
SALINE-SODIC SOIL RECLAMATION WITH STABILIZED SEWAGE SLUDGE AND RECYCLED WASTEWATER
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Saline-sodic soil reclamation can be enhanced with a sustainable and environmental approach by using organic waste materials. Moreover, wastewater can be used in leaching processes to protect freshwater resources in regions with water shortages. The aim
of this study was to reclaim saline-sodic soil by using recycled wastewater and stabilized sewage sludge together with gypsum. The experiment was designed with three replicates using four different sewage sludge doses (0, 4, 8 and 12 kg m-2), an...

ANALYSIS OF CO2 EMISSIONS BETWEEN CONSTRUCTION SYSTEMS: LIGHT STEEL FRAME AND CONVENTIONAL MASONRY
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 Since the emission of greenhouse gases is an important environment issue, this paper presents an analysis of CO2 emissions between two different building methodologies: conventional masonry and light steel frame. To this end, a 70m² building project used in
Social Brazilian Housing Programs (SBHP) built according to both methods was analyzed. In addition to that, the quantitative materials used were determined, according to the building services (infrastructure, superstructure, closing and...

Larus relictus HABITAT HIERARCHICAL EVALUATION BASED ON A DATA DRIVEN APPROACH
Environmental Engineering and Management Journal › Vol. 19 › Nr. 12 The application of Species Distribution Models (SDM) in the management of species habitat and environmental impact changes has been widely used by scientists and ecologists globally, however this study proposes a novel analytical technique involving the combination of a statistical ranking algorithm and Remote sensing GIS data (habitat and threat) to analyze the suitability hierarchy of the habitat of a signature water-bird (Larus relictus). The results indicate that about 47.63% of the study re... Autori: Harrison Odion Ikhumhen ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28339
APPLICATION OF THE AGRO-HYDROLOGIC SWAT MODEL ON THE TAABO RIVER BASIN (CÔTE D’IVOIRE) TO EVALUATE THE EFFECT OF THREE VEGETATIVE FILTER STRIP SCENARIOS ON STREAMFLOW AND NUTRIENTS
Environmental Engineering and Management Journal › Vol. 20 › Nr. 1 Côte d'Ivoire is one of the world's leading producers and exporters of agricultural products. Unfortunately, the multiplicity of stakeholders in this sector and the absence of legislation and regulations have contributed to the pollution of the various hydro systems, particularly those of Taabo river basin. The purpose of this study was to assess the ability of the Soil and Water Assessment Tool (SWAT) model to test the applicability of three vegetative filter strips scenarios to m...
