The study aimed to analyze potential environmental burdens of different waste-to-energy technologies through LCA model. LCA model is developed by SimaPro software by considering Ecoindicator 99 method. Landfill, Incineration, Pyrolysis-Gasification and Anaerobic Digestion are analyzed by considering emission to the atmosphere per unit electricity generation. Results show that, Landfill and Inci...

This paper estimates the economic values of household preference for enhanced solid waste disposal services in Malaysia. The contingent valuation (CV) method estimates an average additional monthly willingness-to-pay (WTP) in solid waste management charges of €0.77 to 0.80 for improved waste disposal services quality. The finding of a slightly higher WTP from the generic CV question than that o...

In Hong Kong, landfill dumping has been a main approach for municipal solid wastes disposal and will be continued in the near future. However, gaseous emission from municipal waste may causes offensive odours and disturbs the neighbours around landfill sites. Usually there are not enough buffer zones between landfill sites and the nearest sensitive receptors due to a land restriction in Hong Ko...

Designing environmentally safe and economically feasible landfills can be a challenging engineering task due to complex interactions that need to be taken into account between landfill size, waste and site characteristics. Performance-based landfill design enables the selection of the most appropriate design components and design details of a landfill to obtain the best overall performance with...

*Corresponding author: [email protected] ABSTRACT: Transfer-transport of the waste is one of key functional elements in solid waste management from technical and financial viewpoint. Unfortunately very few reach activities has been conducted in this field regarding local characteristic of phenomenon which urges undertaking local surveys and research projects. Tehran Organization of Waste...

The details of a semi-aerobic landfill type are described and compared with an aerobic landfill type, particularly related to the characteristics of the solid waste stabilization and the stabilization mechanism. Semi-aerobic landfill is an attempt to lay the leachate collection pipe, comprising the perforated main and branch pipes and gravel, at the bottom of the landfill to discharge leachate ...

background: groundwater is the most important source of water supply in industries and agricultures; therefore the need to protect this valuable resource against pollution is felt more than ever. in this study, the possible impact of yazd municipal solid waste landfill was investigated on the chemical quality of the area’s groundwater. methods: groundwater samples were collected from three well...

7500 tons of municipal solid waste produced in tehran city is land-filled in kahrizak disposalsite. the leachate of the waste has created a lake with 180000m3 in volume. a plant is under construction totreat the leachate. a significant amount of biogas can be produced in anaerobic digestion phase in the treatment plant reactor. the designing process of a power plant in accordance with the produ...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

The aim of the study was to investigate the impact of municipal solid waste incinerator (MSWI) bottom ash (BA) codisposed with municipal solid waste (MSW) on landfill stabilization according to the leachate quality in terms of organic matter and nitrogen contents. Six simulated landfills, that is, three conventional and three recirculated, were employed with different ratios of MSWI BA to MSW. ...
