INTRODUCTION Cities have historically been centers for filth and disease. o Nairobi "The Stinking City in the Sun" o Western Europe prior to the early 19th century Much of the world continues to inappropriately dispose of refuse which: o (1) invites the proliferation of rodents and insects; o (2) becomes a source of contamination to groundwater; o (3) pollutes ambient air when combusted; o (4) facilitates the spread of debris around the dumping site; o (5) lowers property values about the site; and o (6) encourages the spread of disease from microorganisms and toxic chemicals. The Resource Conservation and Recovery Act (RCRA) of 1976 forbade open dumping and introduced the concept of the sanitary landfill. Land fill siting and "NIMBY" The USEPA endorsed several different practices to reduce municipal solid waste (MSW) that include: o (1) source reduction (including reuse of products and backyard composting of yard trimmings); o (2) recycling of materials (including composting); and o (3) waste combustion (preferably with energy recovery) and landfilling.
