Municipal solid waste management is a major challenge, especially in metropolises. This research focuses on a non-technical issue in municipal solid waste management named municipal solid waste separation at the source and seeks to find the best policy in terms of model results. Source separation for recycling has been recognized as a way to achieve sustainable municipal solid waste (MSW) manag...

the present work concerns on the investigation of the role of polyethylene glycols (pegs) as masking agent for amelioration of extraction-separation of la(iii), eu(iii) and er(iii) ions by the acidic extractant bis(2-ethylhexyl)phosphoric acid (dehpa). the studied solvent extraction system is based on the combination of chelating effect of dehpa in the organic phase on the one hand, and the bin...

Abstract The paper presents the results of wind tunnel tests aimed at determining model bottom drag in case rocket tests. balance measurement technique fixed test section by rear sting was discussed. equipped with two parallel boosters. Based on twin values pressure determined for tested Mach numbers. An algorithm corrections shown, which allowed total determination a active or passive flight. ...

considering the increase in waste production, scarcity of land allocated to landfill in urban areas, concerns about ecological damages caused by hazardous waste and damages done to the environment, municipal waste management has become of tremendous importance. the study investigated the behavioral patterns of households regarding waste separation at source using data collected through intervie...
