General Trash/Garbage - Municipal Solid Waste
Municipal solid waste (MSW) includes all items from homes and businesses that people no longer have any use for. These wastes are commonly called trash or garbage and include items such as food, paper, plastics, textiles, leather, wood, glass, metals, sanitary waste in septic tanks, and other wastes. MSW is usually left on the curbside weekly and picked up by a dump truck and taken to a landfill to be buried in a landfill or burned in an incinerator.
MSW is defined in 329 IAC 10-2-115. Construction/Demolition Waste, Industrial Process Waste, Infectious Waste, Coal Combustion Residual (CCR) Waste, Hazardous Waste, and Pollution Control Waste are not MSW. However, a MSW landfill can accept non-hazardous non-MSW waste.
Non-Municipal Solid Waste
Waste that is not created by community activities or residential/commercial establishments are non-municipal solid waste. This could also include solid waste generated by industries.
While creating products, industries produce waste which is called Non-Municipal Solid Waste (NMSW). Manufacturing industry waste is made up of many different waste streams arising from a wide range of industrial processes. Some of the typical industrial sectors found in Indiana include the light and heavy manufacturing, assembly, construction sites, power and chemical plants producing basic metals, ashes, glass, food, beverage, wood and many other products. These industries generate various wastes that came from their pollution control equipment or from their industrial process. Examples of such waste include: water and wastewater treatment sludge, baghouse dust, scrubber sludge, and construction site debris.
This typically includes waste like scrap lumber, drywall, roofing materials, non-asbestos insulation, bricks, concrete, glass, plumbing, and electrical fixtures.
Industrial Solid Waste
Industrial solid wastes include industrial process wastes and pollution control wastes generated by manufacturing or industrial processes that are not hazardous wastes, such as CCR and foundry wastes. A waste classification is needed to dispose this waste in a restricted waste landfill. Based on the constituents’ concentrations, IDEM assigns one of 4 classes (Type I, Type II, Type III and Type IV). Restricted waste site criteria are specified in 329 IAC 10-9-4.
Infectious waste is not a municipal solid waste. Infectious waste is defined by the Indiana Department of Health (IDOH) rules (410 IAC 1-3-10) and Indiana code IC 16-41-16-4 as waste capable of transmitting a dangerous communicable disease.
NMSW not classified as C/D, foundry, coal ash, or flue gas desulfurization (FGD) can be taken to processing facilities, resource recovery facilities, and landfills. This includes manufacturing process wastes, resins, oxides, non-coal combustion sludge, asbestos-containing waste, pollution control/spill cleanup waste, mining wastes, incinerator residues, low level PCB waste, and railroad ties.
