Mumbai, the largestmetropolitan city in India, generated 6,256 tons ofwaste per day in 2001. It is the responsibility of the Municipal Corporation of Greater Mumbai (MCGM) to provide Municipal Solid Waste (MSW) management services; however, the MCGM is not able to handle the increasing quantity of waste. As a result, waste litters all over the place giving rise to health and environmental probl...

THE CITY OF COLOMBO , which has a resident population of little over half a million, and a total area of 3731 hectares, is administered by a Municipal Council. The collection and disposal of solid waste generated within the City is a function of the Municipal Council, and is carried out by its six district offices. The Colombo Municipal Council (CMC) collects around 500 metric tons of solid was...

The three processes of urbanization, industrialization and globalization are positively correlated with municipal solid waste generation and energy consumption in global urban centers. Heavy reliance on fossil fuels in most world cities has contributed not only to global warming and climate change, but also to astronomical increases and volatility in the prices of energy sources. Africa has suf...

The main purpose of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as municipal solid waste residue. In the present investigation, we aim to isolate the two novel cellulase producing fungi (Aspergillus niger and Trichoderma sp.) from municipal solid waste. Municipal solid waste residue (4-5% (w/v)) and pep...

escalating development of tourism and petroleum industries in small islands such as lavan-iranrequires sound solid waste management. in the present investigation, three scenarios which consist of thecombination of landfill, recycling, incineration and composting and their environmental impacts have beenevaluated for 7514 kg/day of waste generation in lavan island. for this purpose, life cycle a...

background and purpose: an appropriate solid waste (sw) disposal has been a major problem in municipal environment. the use of landfills is the most economical and environmentally acceptable method for the disposal of sws all over the world. however, landfill leachate can cause environmental issues such as soil and ground water pollution. so, finding suitable land fill site is one of the most s...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 680...

due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...

Public-private partnerships in urban environmental services have witnessed increased interest in recent years primarily to reform the weak performance of the public sector, reduce cost, improve efficiency, and ensure environmental protection. In this context, successful public-private partnerships require a thorough analysis of opportunities, a deliberate attention to process details, and a con...

The aim of this study is to identify and measure the variables which influence per capita municipal solid waste generation in the south-eastern U.S., using the 100 counties of North Carolina as a data set and regression models for statistical analysis. Variables are selected to capture the residential, institutional and commercial components of the municipal solid waste stream, as well as the o...
