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...

An attempt has been made to develop Water Quality Index (WQI), using six water quality parameters at riverside stations located in the vicinity of temples of Dakshina Kannada district, Karnataka, South India. Rating curves were drawn based on the tolerance limits of inland waters and health point of view. Bhargava WQI method and Harmonic Mean WQI method were used to find overall WQI along the stretch of the river basin. Five point rating scale was used to classify water quality in each of the st...

Abstract The etching of iron materials in sulphuric acid solutions allows the dissolution of the iron oxides with formation of iron sulphates. The relatively low solubility of the formed sulphates imposes their separation for avoiding the contamination of the etching bath, as well as for preventing the environmental pollution through the wastewater. Within the flow sheet of the processing of the hot or cold rolled steel, a stage of separation by crystallization of iron sulphate is foreseen. T...

Abstract Textile industry is one of the most pollutant and water consuming industries. Large quantities of water are required in materials preparation and dyeing, so consumption and waste generation have become serious concerns for textile manufacturers and finishers. Textile effluents are characterized by high values of quality indicators such as BOD and COD, suspended solids and heavy metals. A serious environmental problem and also an aesthetic problem is the color of the effluent. Reactiv...

The results showed that ClO2 could remove part of DOM and the removal rate of hydrophobic (HO) component b...

The beneficial effect of urban plants in improving air quality is often mentioned in literature but is seldom quantified and valuated. Quantification and valuation of the benefits provided by urban plants allow direct comparison between plant species and help make more informed urban planning decisions.

Abstract Some of the major stressors of air quality in the urban areas are nitrogen oxides, ozone and suspended particles. The effect of air pollution on respiratory diseases can increase considerably at high levels of pollution and might trigger asthma symptoms. Longterm exposure can increase the rate of respiratory infections and symptoms at population level, but particularly in children. The goal was to analyze with statistical techniques the pollutant concentrations (NO, NO2, and SO2) re...

The Amara Lake is located at the south-eastern part of Romania. It is a shallow lake with an average depth of 3m and average extent of 1.32 km2, having a particular importance for the area in which is situated. This importance derives from its main functions in the ecosystem, namely: source of food, shelter and breeding place for almost 54 bird, balneary tourism attraction and jobs for the residents of Amara who live in the northern part of the lake. Under these conditions, the sustainable devel...

The expansion of the urban areas...

In recent years the organizations’ has gone from resource-based economy to a knowledge based economy. Likewise the organizations’ success in this turbulent environment depends on its sustainable orientation which implies integration of various management practices. Such a management practices considered to be a driving force to sustainable development are environmental management system (EMS) and knowledge acquisition. In this context, it’s required to measure the organizationa...

Livestock production is under growing public and scientific scrutiny for its greenhouse gas (GHG) emissions. This article contains a preliminary assessment of the inclusion of upstream life-cycle GHG emissions in concentrated feeds design, using the most common nonlinear programming optimization algorithms to determine feed composition. First, GHG emissions are included as costs in a single criteria optimization problem. The unit price of GHG emissions was obtained using a genetic algorithm. Sec...

According to EU Strategy for the Baltic Sea Region, Lithuania obligates to ensure sustainable growth, gain and maintain good condition of marine environment until 2020. In accordance with the sustainability approach, every potential cost and energy cutting as well as social sustainability measure for wastewater treatment should be explored. Nonetheless, Lithuania wastewater treatment plants (WWTP) in the sustainability context have never been evaluated before. A comprehensive set of 30 sustainab...

Groundwater pollution investigation near old and closed landfill sites is increasingly attracting more attention. Nitrogen compounds, especially those leached from the landfill area, are often regarded as a main pollution source for the groundwater. This study investigated the nitrogen pollution in the groundwater near a closed old landfill area of Beijing, China. The field investigation showed that the nitrate-polluted groundwater was determined as Class VI (refers to bad quality) at the detect...

Social upgradation results more postconsumer glass and plastic waste and continuously demands newer techniques for their management. This research proposes a new waste-to-waste management strategy by using waste glass for polyolefin degradation. For this purpose, waste glass is activated by mechanochemical treatment and resultant material is used for the thermal pyrolysis of polyolefin. Certain improvement in the product quality is achieved by selectivity towards more alkane fraction. ...

The influence of the active compound of Moringa oleifera Lam (MO) seeds was evaluated by different methods for the preparation of the natural coagulant in the treatment of surface water. Nine methods were analyzed, comprising samples of seed powder with different granulometry, aqueous and saline solutions, evaluated before and after oil extraction from MO seeds. Tests of coagulation/flocculation and sedimentation were accomplished using simple Jar Test. Natural coagulant dose of 50 mg.L-1 identi...

This paper describes an eco-efficiency decision support model for of end-of-life solid waste recycling. A holistic approach in balancing environmental pollution concern and waste recycling is required. A system dynamic model is based on mathematical model of the supply chain, and decision-making analysis is supported with the online spreadsheets. A criterion function-based modelling is used as a core model for simulation that uses net present value-based metrics of the supply chain activities. T...

The paper presents a Multi-Criteria Decision Analysis (MCDA) methodology to analyze environmental performance indicators of an organization designed according to Eco-Management and Audit Scheme III - Regulation (EMAS III). The newly proposed indicators are intended to achieve Best Environmental Management Practice (BEMP) to facilitate and harmonize the way the environmental performance is reported and analyzed periodically within the Environmental Management System (EMS) of the organization.
