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...

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...

AbstractLead is unique among the toxic air contaminants that the World Health Organization (WHO) has identified it in several ways. Lead concentration is increasing rapidly in the environment due to increased use in anthropic activity. Lead is released into the atmosphere from metallurgy and siderurgy industry, during coal burning, oil or wastes, from power plants which use solid fuel, from traffic and the building sites. Regardless the exposure mode, the presence of lead in urban air, even in r...

AbstractThe mechanisms in the shaping of organic food in Denmark since the 1970'ies are analysed as a contribution to the discussion of strategies for a more sustainable production and consumption of food. The background is the major  achievements in Denmark within organic food since the 1970'ies, but also the recent years' reduction in the land converted to organic farming. The analyses are based on experiences from projects, analyses and literature and draw on innovation theory and theory...

A part of the corrosion products are soluble compounds of divalent and trivalent iron, the iron dissolution being accelerated when divalent ions are formed and in the case of the aerated seawater. The solid corrosion product formed during corrosion in seawater is principally oxy-hydroxide (FeOOH), but were identified small quantities of Fe2O3, Fe3O4 and so...

AbstractIn industrial plants many types of combustible dusts are generated, processed, handled and stored. When ignited, they can burnrapidly and with a considerable explosion force, when mixed with air in proper proportions. This is the reason why adequateprecautions have to be adopted, to ensure all equipment is appropriately protected so that the ignition likelihood of the explosiveatmosphere is diminished.Explosion preventing and protection precautions aim to stop explosion occurrence, by el...

The composition and the structure of the soil matrix have an important role in determining the water and the air regime into the soil. In the soil pore the area occupied by water and air, capillary and adsorption phenomena occur, together defining the suction of the matrix. The suction-humidity relationship varies from one soil to another, but also to the same soil in time. This paper sets out the results of investigations aimed at highlighting the influence of the composition and structure of...

Globally the researchers are identifying the new ways for better urban sustainability. One major issue in the current world is the lack of fresh water availability in cities due to rapid increase in the population. To meet water requirement, scientist are exploring different ways to enhance the groundwater recharge capacity. One such solution is the use of building information modelling (BIM) technology to identify multiple structures that can be constructed to provide the potential recharge. T...

This paper develops investigations in the field of analytic hierarchy techniques that could be applied in public transportation systems. The study focuses particularly on the public transport bus services in Bucharest, the capital of Romania. The research aims to investigate the methodological feasibility of the analytic hierarchy process to analyze and measure the perceptions and needs of the Romanian public transportation users. Towards this objective, the study presents the current state of t...

The heavy dependence on fossil-based energy and inefficient use of energy add to the relentless growth of carbon emissions in China, and also lead to an array of serious environmental pollution issues, such as haze and smog. This situation threatens the health of residents and the sustainable development of society. China has to face the huge pressure of carbon emissions from international and domestic societies. This study aims to investigate the demographic driving factors of carbon emission ...

As one of China’s fastest growing regions, Beijing–Tianjin–Hebei (B-T-H), which contains one of the most intensive logistics networks in China, developed rapidly from 2005 to 2016. However, such growth also led to increases in energy consumption and carbon emissions. From 2005 to 2011, the growth rate of logistics carbon emissions in the B-T-H was maintained at 8%–10%. Subsequently, owing to policies and technological progress related to energy saving and emission reducti...

Brominated flame retardants (BFRs) are used in different types of products such as plastic, textiles and electronic circuits with the aim to increase fire resistance and to avoid or to delay the propagation of accidental combustion. However, high concentrations of bromine in waste from electrical and electronic equipment (WEEE) hinder the possibility of their use as secondary raw materials. Furthermore, the possibility that BFRs can be released during mechanical recycling processes, imposes the...

Space exploration requires reliable, rapid, significant and safe methods for preventing, monitoring and controlling biocontamination risk in water loops and humid areas in manned Space habitats. Water is one of the most important resources of our everyday life. Its microbiological control in houses, public water dispensers and special conditions (e.g.: epidemics, catastrophes, isolation) is crucial. The presented solution is automated, compact and portable, and above all “integrated&rdquo...

Groundwater at an abandoned industrial area near Bergamo, Italy, was historically contaminated by tetrachloroethylene (PCE) (>100 μg/L) and, to a lesser extent, by trichlorethylene (TCE), dichloropropane (DP) and 1,1,2,2-tetrachloroethane (R-130). A liquid reagent (EHC® Liquid) was selected for remediation of groundwater at the site. The reagent is provided in two parts: EHC® Liquid Mix (a soluble organo-iron salt), and ELS® Microemulsion (a lecithin-based carbon substrate), a...

This paper aims to investigate the root characteristics of three woody species (Pinus brutia, Quercus coccifera and Spartium junceum) planted on steep soil-denuded slopes, surfaced after ring-road excavation. The planted slopes were almost vertical, south faced and adding no soil. Fifteen plants per species were manually extracted for root system analysis and testing. The findings showed that the survivorship was different among the investigated species with S. junceum plants to survive better. ...

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...

Fish meal processing industries convert the raw fish into a various commercially edible form. The effluent generated from this industry comprises a large amount of pollutants leading to high values of biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS). Mostly traditional biological and chemical methods have been adopted to treat the effluent coming out of the fish meal industry. By using these traditional methods at the end of the process, a large amo...
