Definitions
What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person.
Though waste is a physical object, its generation is a physical and psychological process.
The definitions used by various agencies are as below.
United Nations Environment Program
According to the
of 1989, Art. 2(1), "'Wastes' are substance or objects, which are disposed of or are intended to be disposed of or are required to be disposed of by the provisions of national law".
[“Basel Convention.” 1989. ]
United Nations Statistics Division
The UNSD ''Glossary of Environment Statistics''
[''Glossary of Environment Statistics''](_blank)
. 1997. UNSD. Updated web version 2001. describes waste as "materials that are not prime products (that is, products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose. Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded."

concluded that 292.4 tons of municipal waste was generated which equated to about 4.9 pounds per day per person. Out of the 292.4 tons, approximately 69 million tons were recycled, and 25 million tons were composted.
Household Waste and Commercial Waste
Household waste more commonly known as trash or garbage are items that are typically thrown away daily from ordinary households. Items often included in this category include product packaging,
yard waste

across the world. In the United States, it is estimated that 11.3 million tons of textile waste is generated. On an individual level, it is estimated that the average American throws away 81.5 pounds of clothes each year. As online shopping becomes more prevalent, items such as cardboard, bubble wrap, shipping envelopes are ending up in landfills across the United States. The EPA has estimated that approximately 10.1 million tons of plastic containers and packaging ended up landfills in 2018. The EPA noted that only 30.5% of plastic containers and packaging was recycled or combusted as an energy source. Additionally, approximately 940,000 pounds of cardboard ends up in the landfill each year.
Commercial waste is very similar to household waste. To be considered as commercial waste, it must come from a business or commercial occupancy. This can be restaurants, retail occupants, manufacturing occupants or similar businesses. Typically, commercial waste contains similar items such as food scraps, cardboard, paper, and shipping materials. Generally speaking, commercial waste creates more waste than household waste on a per location basis.
Construction and Demolition Waste
The EPA defines this type of waste as “Construction and Demolition (C&D) debris is a type of waste that is not included in municipal solid waste (MSW).”
Items typically found in C&D include but are not limited to steel, wood products, drywall and plaster, brick and clay tile, asphalt shingles, concrete, and asphalt. Generally speaking, construction and demolition waste can be categorized as any components needed to build infrastructures. In 2018, the EPA estimated that the US generated approximately 600 million tons of
C&D waste.
The waste generated by construction and demolition is often intended to be reused or is sent to the landfill. Examples of reused waste is milled asphalt can be used again for the asphalt mixture or fill dirt can be used to level grade.
Hazardous Waste
The EPA defines hazardous waste as “a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment.”

(DOI). Each agency plays an important role in creating, handling, and properly disposing of radioactive waste. A brief description of each agency’s role can be found below.
NRC: “Licenses and regulates the receipt and possession of high-level waste at privately owned facilities and at certain DOE facilities.”
DOE: “Plans and carries out programs for sand handling of DOE-generated radioactive wastes, develops waste disposal technologies, and will design, construct and operate disposal facilities for DOE-generated and commercial high-level wastes.”
EPA: “Develops environmental standards and federal radiation protection guidance for offsite radiation due to the disposal of spent nuclear fuel and high-level and transuranic radioactive wastes.”
DOT: “Regulates both the packaging and carriage of all hazardous materials including radioactive waste.”
DOI: “Through the U.S. Geological Survey, conducts laboratory and field geologic investigations in support of DOE’s waste disposal programs and collaborates with DOE on earth science technical activities.”
The US currently defines five types of radioactive waste, as shown below.
High-level Waste
High-level waste (HLW) is a type of nuclear waste created by the reprocessing of spent nuclear fuel. It exists in two main forms:
* First and second cycle raffinate and other waste streams created by nuclear reprocessing.
* Waste formed by vit ...
: This type of radioactive waste is generated from nuclear reactors or reprocessing spent nuclear fuel.
Transuranic Waste
Transuranic waste (TRU) is stated by U.S. regulations, and independent of state or origin, to be waste which has been contaminated with alpha emitting transuranic radionuclides possessing half-lives greater than 20 years and in concentrations gre ...
: This type of radioactive waste is man-made and has an atomic number of 92 or higher.
Uranium or thorium mill tailings: This type of radioactive waste is a result after the mining or milling or uranium or thorium ore.
Low-level waste
Low-level waste (LLW) or Low-level radioactive waste (LLRW) is nuclear waste that does not fit into the categorical definitions for intermediate-level waste (ILW), high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or ce ...
: This type of radioactive waste is radioactively contaminated waste. It is typically generated from industrial processes or research. Examples of these items include paper, protective clothing, bags, and cardboard.
Technologically enhanced naturally-occurring radioactive material (TENORM): This type of radioactive waste is created through human activity such as mining, oil and gas drilling, and water treatment where naturally-occurring radiological material (NORM) becomes concentrated.
Energetic Hazardous Waste
The EPA defines energetic hazardous waste as “wastes that have the potential to detonate and bulk military propellants which cannot safely be disposed of through other modes of treatments.”
The items which typically fall under this category include
munitions
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weap ...
, fireworks, flares, hobby rockets, and automobile propellants.
Munitions
Munitions were added to hazardous waste in 1997 when the EPA finalized RCRA. A special rule was added to address munitions in waste. This new rule is commonly referred to as the Military Munitions Rule.
The EPA defines military munitions as “all types of both conventional and chemical ammunition products and their components, produced by or for the military for national defense and security (including munitions produced by other parties under contract to or acting as an agent for DOD—in the case of Government Owned/Contractor Operated

The entire rule can be foun
here While a large percentage of munitions waste is generated by the government or governmental contractors, residents also throw away expired or faulty ammunition inside their household waste.
Fireworks, Flares, and Hobby Rockets
Every year, the US generates this type of waste from both the commercial and consumer aspects. This waste is often generated from fireworks, signal flares and hobby rockets which have been damaged, failed to operate or for other reasons. Due to their chemical properties, these types of devices are extremely dangerous.
Automobile Airbag Propellants
While automobile airbag propellants are not as common as munitions and
fireworks
Fireworks are a class of Explosive, low explosive Pyrotechnics, pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a l ...
, they share similar properties which makes them extremely hazardous. Airbag propellants characteristics of reactivity and ignitability are the characteristics which qualify for hazardous waste. When disposed undeployed, leaves these two hazardous characteristics intact. To properly dispose of these items, they must be safely deployed which removes these hazardous characteristics.
The EPA includes the waste of automobile airbag propellants under the RCRA. In 2018, the EPA issued a final rule on handling of automobile airbag propellants. The
interim final ruleprovides an exemption of entities which install and remove airbags. This includes automobile dealerships, salvage yards, automobile repair facilities and collision centers. The handler and transporter are exempt from RCRA, but the airbag waste collection facility is not exempt. Once the airbags have met the collection center, it will then be classified as RCRA hazardous waste and must be disposed or recycled at a RCRA disposal facility.
Electronic Waste

Mixed Waste
Mixed waste is a term that has different definitions based its context. Most commonly, Mixed Waste refers to hazardous waste which contains radioactive material. In this context, the management of mixed waste is regulated by the EPA and RCRA and
Atomic Energy Act. The Hazardous materials content is regulated by RCRA while the radiological component is regulated by the Department of Energy (DOE) and Nuclear Regulatory Commission (NRC).
Mixed waste can also be defined as a type of waste which includes recyclable materials and organic materials.
Some examples of mixed waste in this context include a combination of broken glassware, floor sweepings, non-repairable household goods, non-recyclable plastic and metal, and clothing and furnishings. Additionally, ashes and soot, residential renovation waste materials are also included under this definition.

With the addition of wastewater treatment facilities with spending a few million dollars and infrastructure to clean our areas and freshwater to reuse instead of over-using our land and water supply, which would be the greatest cost. Another cost of not adding wastewater treatments in countries is that people have no choice but to clean with, cook with, or drink the contaminated water which has caused millions of disease cases and deaths. “Between 400,000 and 1 million people die each year in developing countries because of diseases caused by mismanaged waste, estimates poverty charity Tearfund”.
