Part l Solid Waste Engineering 12 Evolution of Solid Waste Management 12.1 Solid Waste-a Consequence of Life Problems with the disposal of wastes can be traced from the time when humans first began to congregate in tribes, villages, and communities and the accumulation of wastes became a consequence of life

12.2 Waste Generation In a Technological Society Materials flow and waste generation The effects of Technological Advances Of particular significance are the increasing use of plastics and the use of frozen foods, which reduce the quantities of food wastes in the home but increase the quantities at agricultural processing plants

Thus, the engineers responsible for the design of solid waste facilities must be aware of trends. even though they cannot, of course, predict all the changes in technology that will affect the characteristics of solid wastes But important questions arise: Which elements of society generate the greatest quantities of solid waste and what is the nature of these wastes? How can the quantities be minimized? What is the role of resource recovery? Can disposal and recovery technology keep up with consumer product technology

123 The Development of Solid Waste Management Solid waste management may be defined as the discipline associated with the control of generation, storage, collection, transfer and transport, processing, and disposal of solid wastes in a manner that is in accord with the best principles of public health, economics engineering, conservation, aesthetics, and other environmental considerations and that is also responsive to public attitudes

In its scope, solid waste management includes all administrative, financial, legal, planning, and engineering functions involved in solutions to all problems of solid wastes. The solutions may involve complex interdisciplinary relationships among such fields as political science, city and regional planning, geography, economics, public health, sociology, demography, communications and conservation, as well as engineering and materials science

Functional Elements of a Waste Management System The activities associated with the management of solid wastes, from the point of generation to final disposal have been grouped into the six functional elements: waste generation;(2 waste handling and separation, storage, and processing at the source; 3)collection;(4) separation and processing and transformation of solid wastes;(5) transfer and transport; and (6)disposal
