Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), also known as the Superfund Act
Mass burn incinerators: When the waste has been completely burned, the ash, known as bottom ash, is processed to remove any remaining metals. The combustion gas that is produced during the burning of the waste is moved through a structure called a scrubber, where the gas is chemically treated to remove hazardous components and neutralize noxious gases, such as sulfur dioxide.
During this process, many gases are turned into water and salts. These particulates that form are referred to as fly ash. The remaining gas and the fly ash are then passed through a structure known as the baghouse, which filters out the particulates. This last step lowers the amount of pollutants entering the air. The remaining gas is released through smokestacks and the fly ash collected is combined with the bottom ash from the waste and transported to a landfill.
How is the baghouse structure important in the mass burn incinerator?
It filters out particulates.
Which type of compost system utilizes the technique of windrows?
Large-scale composting by municipalities
__________ is the term used to describe liquids that leach or leak from the landfill
