Currently, the management of solid waste represents a major economic and environmental issue throughout the world. Trends in waste generation show an increase in the volumes of waste produced in most countries and it is clear that the trend will continue. The treatment and disposal of solid waste involves a range of processes including landfill, incineration and composting, all of which may result in emissions to the environment. Municipal investments are said to be highly capital-intensive. As a result, every investment needs to be preceded by the economic analysis which allows for the estimation of the effectiveness of the investment. Investments are made to make profits and to increase savings. This book presents current research in the study of municipal solid waste, with a particular focus on recycling and cost effectiveness.
