background: developing cities like khulna, the third largest metropolitan city in bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (ngos) and community-based organizations (cbos) in municipal solid waste (msw) management. methods: a survey ...

tehran has a population of over 12 million and produces more than 7500 tons of waste every day. tehran’s municipal solid waste is processed and landfilled at kahrizak disposal center. due to inappropriate waste management, a lake with a leachate volume of 180,000m3 has been formed. to solve this problem a leachate treatment plant is currently under construction. a byproduct of leachate treatmen...

a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...

1.0 Problem Statement The disposal of municipal solid wastes is one of the most serious problems facing Waste generation is on the increasing trend due to exponentially renders waste management as a significant problem. The solid waste generation (lb/capita/day) has been on increasing trend since 1980, with the curr New York State alone generates 8.4 million tons of municipal solid waste per ye...

This paper presents an overview of current solid waste management practices in Kohima, Nagaland, India and suggests solutions to some of the major problems. The levels of socio-economic development determine the quantity and composition of solid waste. Higher the level of economic development, greater the proportion of waste composition. The total population of the city is 1,32,836, among those...

Waste disposal is one of the pressing problems.Millions of tons of municipal solid waste, hazardous/industrial wastes and agricultural wastes are handled daily throughout municipal areas. Each municipality confronts great challenges in disposing of its wastes in an efficient, cost effective and environmentally safe manner.Landfills in metropolitan areas are becoming full, and new ones are more ...

Some contaminants emitted by municipal waste incinerators are believed to adversely affect reproductive health in the exposed populations; yet only limited and conflicting epidemiologic evidence on this issue has been provided so far. In this study we analyzed rates of spontaneous abortion and prevalence at birth of congenital anomalies in women residing or working near the municipal solid wast...

Municipal domestic waste is the most complex one among the solid wastes. Its improper disposal will easily cause serious environmental pollution, occupy substantial landfill and waste the recyclable resources. System dynamics methodology presents special merits in the study of the municipal waste management. In this paper, 16 study achievements of the system dynamics are summarized with regard ...
