Document Summary
Modern packaging materials are durable and degrade much more slowly - plastic bags: 1 second to produce, 20 minutes in use, 400 to 600 years to break down. Type of waste: municipal solid waste: non-liquid waste from homes, institutions, and small businesses. Incineration in specially constructed faculties is an improvement over open-air burning of trash. Remaining ash must be disposed of in a hazardous waste landfill. Hazardous chemicals are created and released during burning: people tend to distrust incineration, but modern incinerators are pretty clean. Pay-as-you-throw = uses financial incentives to influence consumer behavior - the less waste a house generates the less it is charged for trash collection. The rising cost of waste disposal encourages industries to decrease waste and increase physical efficiency. There are three disposal methods for hazardous waste : Design and construction standards are similar but stricter than ordinary sanitary landfills. Must have several impervious liners and leachate removal systems.
