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...

AbstractMalaysia is a country that has recorded a phenomenal economic development success story. One of the most important problems is solid waste due to inadequate management practices. This resulted in an increase in the amount of waste generated. The national average in at 0.5-0.8 kg/person/day, but in the cities the figures have escalated to 1.7 kg/person/day. This paper addresses the current practice of solid waste management and its disposal in Malaysia. Currently, the waste management app...

Abstract:Incineration plants are used since the beginning of the twentieth century to transform the mixed municipal waste into thermalenergy and to convert the hazardous components of waste into harmless compounds. To minimize the environmental pollutionand maximize the energy efficiency of the produced energy, the control of the complex processes that occur into the waste toenergy conversion is of major importance. In this work, the system identification approach is used to determine the dynami...

However, participatory tools are not yet used as a matter of course in the Romanian forest sector. This study aimed to stress the importance of corporate social responsibility (CSR) in decision making in the forest sec...

Abstract In the context of biogas sustainability assessment, a promising way to reach greenhouse gases (GHG) reduction and fossil energy savings is the anaerobic digestion (AD) of both animal manure and energy crops. Nowadays, more than 1,100 AD plants are working in Italy, mostly located in Northern Regions. To those plants with an electrical power lower than 1 MW, strong public incentives were given, therefore, several of them have been put into operation; this entailed increasing cereal ...

The model is derived based on the nonlinear regression analysis by using the Richardson’s extrapolation method and the Levenberg–Marquardt algorithm. The application of the model has been explored for a wide range of eleven fundamental biological design variables and tested against a total of 1500 additional computational scenarios ...

Stillage (distillery wastewater) is a major waste by-product from process of bioethanol production. It contains large amounts of organic matter and suspended solids, so it should not be disposed in the nature before previous treatment. This work studies the application of ceramic microfiltration membrane for stillage purification. Also, the influence of operating factors on permeate flux and removal efficiency was investigated using Response Surface Methodology. The factors considered for design...

Porous membranes as gas-liquid contactors are widely used in carbon dioxide (CO2) absorption systems. It provides larger mass transfer area and excellent operational flexibility. Membrane contactors have been considered as alternative to conventional approaches in removing CO2. In spite of its advantages over conventional technologies, membrane wetting is a major problem which reduces performance of CO2 absorption. This paper explains the concept of membrane wetting phenomenon and its influen...

In the former Carbochimica site of Fidenza, a bioremediation approach was developed using the technique of biodegradation of pollutants thanks to a selected autochthonous bacterial-fungal consortium. The soil was heavily polluted up to values of total hydrocarbon equal to 1800 mg/kg. The consortium was selected from the microorganism living in the Fidenza soil, bioaugmented and finally reinoculated in the bio-pile for soil treatment. The approach is absolutely innovative, due to the presence not...

Multiple activities carried out on coastal areas expose marine sediments to contamination and their management has a great socio-economic importance with a high impact on economic development of coastal areas. However, there is an increasing shift towards the use of more sustainable approaches for managing ‘contaminated’ sediments. Using a case study of the Favignana Habour in Italy, this paper evaluates three approaches for the management of these sediments. The results of simulatio...

Agriculture is a highly water-demanding sector. Developed in recent years, the precision farming approach allows to optimize irrigation without compromising crops productivity. WSN networks are a key element of this approach because they allow to monitor continuously large number of parameters providing the possibility of a real-time intervention on field management practices. The WSN networks can be used to measure traditional parameters such as precipitation, soil moisture, or irradiation and ...

The study describes the start-up phase of the door-to-door separate collection service of municipal solid waste (MSW) in a large metropolitan area, analysing not only the performance in terms of separately collected waste but also the feedback from citizens on how to improve it. For the scope, the case study of the city of Bari (Southern Italy) was considered. The methodological approach involved primarily the subdivision of the entire municipality into eight homogeneous territorial zones (HTZ) ...

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...

Nowadays, there is a growing interest on developing new assessment criteria of sediment ecological quality for setting priorities and management strategies of contaminated materials. According to the literature, the weight of evidence (WOE) approach has been developed to provide a multidisciplinary characterization which combines di...

Municipal wastewater treatment is a global issue and an expensive process. Treatment of the wastewater using algal growth is a cost-effective approach, because of easy propagation of algae in wastewaters through utilization of most of the nutrients and in turn reduces the pollution load. As a preliminary research work, laboratory scale studies were done using native algal species collected from particular sources. They were grown in different pond waters to observe the biomass development in co...

As CO2 concentration levels in the atmosphere are steadily reaching a point of no return, it is paramount that actions are taken towards mitigating emissions by improving the efficiency of existing processes. Sorption-enhanced water-gas shift (SEWGS) combines the water-gas shift reaction with in-situ adsorption of CO2 on potassium-promoted hydrotalcite (K-HTC). This enables a direct conversion of syngas into separate hot streams of H2 at feed pressure and CO2 at regeneration pressure, making th...

Cargo owners put the elements of time and price of service into the forefront, where the degree of pollution (CO2, NOx, SO2, PMs) and the need for energy efficiency is too often ignored. Various studies highlight the lack of methodological approaches to the standardized evaluation of the environmental impacts of intermodal transport, thus the aim is to formulate a modul...
