Hydrocarbon-containing wastes and wastewaters are produced worldwide by the activities of oil gas industry. Anaerobic digestion has potential to treat these waste streams, while recovering part its energy as biogas. However, hydrocarbons toxic compounds that may inhibit microbial processes, particularly methanogens. In this work, toxicity hexadecane (0–30 mM) towards pure cultures hydrogenotrop...

forecasting of municipal waste generation is a critical challenge for decision making and planning,because proper planning and operation of a solid waste management system is intensively affected by municipal solid waste (msw) streams analysis and accurate predictions of solid waste quantities generated. due to dynamic and complexity of solid waste management system, models by artificial intell...

a large portion of municipal waste, disposed in landfills, is organic in nature. this organicmaterial starts decomposing soon after the disposal in landfills. the decomposition leads to the generation ofin situ leachate, and this leachate can contain substantial amounts of contaminants. under arid conditions,leachate is solely generated by waste decomposition, as little input of external water ...

The generation and accumulation of waste of electrical and electronic equipment (WEEE) is growing fast, becoming one of the most complex waste streams the modern world faces. The effective and efficient management of this waste stream raises the interest of the global scientific and business community. The purpose of this paper is to analyze the flow in an e-waste management system, present the...

This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during composting. Three experiments in lab-scale pilots (300 L) were performed for each waste, each one under a constant aeration rate. The aeration rates applied were comprised between ...

1 This paper aims to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge 2 and green algae regarding their biodegradability, their stabilization kinetics and their temperature rise during 3 composting. Three experiments in lab-scale pilots (300L) were performed for each waste, each one under a 4 constant aeration rate. The aeration rates applied were comprised b...

Membrane assisted liquid extraction(MALE) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. The present contribution outlines the classification of membrane assisted ...

The purpose of this study was to judge the feasibility of gasification for the disposal of waste streams generated through salmon harvesting. Gasification is the process of converting carbonaceous materials into combustible "syngas" in a high temperature (above 700 degrees C), oxygen deficient environment. Syngas can be combusted to generate power, which recycles energy from waste products. At ...

Waste electrical and electronic equipment is one of the major world-wide waste streams triggering the emergence of environmental strategies. Environmental regulations, closed-loop supply chain (CLSC) activities and design-for-environment (DfE) practices are environmental friendly strategies being implemented by governments and industry. In this paper, we apply a System Dynamics model to a CLSC ...
