Abstract
Solid waste management is one of the biggest issues in India as well as in the world. The generation of solid waste should be estimated for proper management of municipal solid waste (MSW) of the cities.The segregation, collection, transportation and disposal of municipal solid waste (MSW) are currently done in very unscientific and causal way in India and in many other developing countries. This creates problem for environment in terms of water, air and odour pollution. In this study, municipal solid waste has been estimated for Patna city and management has been carried out from the point of view of the recovery resources. The components of MSW have been estimated and based on that, moisture, density and energy content have been quantified. Afterwards, chemical compositions have been calculated and chemical formula has been made for MSW. This composition can help to estimate requirement of oxygen to degrade MSW and recovery of methane and carbon dioxide from MSW. Generally, landfill for solid waste management is planned for fifteen years or more than that. It is carried out in several parts or layers which take many years. In this paper, the calculation of energy content, requirement of oxygen to degrade MSW and recovery of methane, carbon dioxide from MSW have been carried out for a year which can be done for whole landfill period.
Highlights
Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue[1]
The physical characteristics of solid waste for Patna city were taken from a study 12
Chemical composition was estimated for municipal solid waste (MSW) using typical values of MSW component[14]
Summary
Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue[1]. Urbanization is increasing the level of air, noise, water pollution and solid waste generation their complexities[2]. The quantity of municipal solid waste (MSW) has increased tremendously with improved life style and social status of the populations in urban centers[3]. The municipal solid waste management is not well structured at many places in India[5]. Municipal corporations in developing countries are not able to handle increasing quantities of waste, which results in uncollected waste on roads and in other public places[6]. Solid waste management is one among essential services provided by municipal authorities in the country to keep urban centers clean.
