STUDIES ON SOLID WASTE MANAGEMENT WITH SPECIAL REFERENCE TO IMPROVED DESIGN OF COMMUNITY BIN

Abstract

Solid wastes are all the wastes arising from human and animal activities that are normally solid and that are discarded as useless or unwanted. In an urban setting, the accumulation of solid waste is a direct consequence of life. Solid waste management discipline is associated with the control of generation, storage, collection, transfer and transport, processing and disposal of solid waste in a manner that is in conformity with the best principles of public health, economics. Engineering conservation, aesthetics and other environmental consideration, while studying on solid waste management system provided in U.O.R. a number of shortcomings have been identified. The community bin, provided by the side of the road for dumping solid waste into it are open and are easily approachable by stray cattle. Cattle such as cow and dogs go inside it and scatter the solid waste not only in the vicinity of community bin but also on the road. A very unhygienic condition is created by this and it mars the beauty of the campus. At the same time the open community bin is a place for mosquito breeding and different diseases are the consequences of this. The size and shape of community bin is also not appropriate. Due to inappropriate size a particular community bin is under filled while the other is overfilled. The aim of this work/dissertation was to design an effective community bin which could help in solving some of the above mentioned problems. For designing an appropriate community bin it is extremely necessary to assess the present Solid Waste Management System in U.O.R. for this requisite iii data about the existing community bin was collected and community bins were surveyed. On the basis of this study and the questionnaire conducted from the residents of Saraswati Kunj Colony, an appropriate community bin was designed and constructed. At the same time appropriate shape and size also has been suggested for every community bin. The required plan area for every community bin has been calculated taking height to be equal to 1.2 m. so, if a particular community bin has to be corrected, it can be done only by changing dimensions of one side. Similarly, if one decides not to change the dimensions of community bin, the degree of cleaning has to be altered, which was calculated for every community bin. The physical and chemical characteristics of solid waste from U.O.r. and from 33 Indian cities was studied. On the basis of this an appropriate method of disposal of solid waste from the U.O.R. campus has been suggested. Composting appears to be the best alternative for disposal of solid waste obtained from U.O.R. campus. Indoor process of composting was though to be the best alternative and a brief design for U.O.R. campus has been suggested.
