Garbage, trash, rubbish, or refuse is waste material that is discarded by humans, usually due to a perceived lack of utility. The term generally does not encompass bodily waste products, purely liquid or gaseous wastes, or toxic waste products. Garbage is commonly sorted and classified into kinds of material suitable for specific kinds of disposal. [1]
The word garbage originally meant chicken giblets and other entrails, as can be seen in the 15th century Boke of Kokery, which has a recipe for Garbage. [2]
What constitutes garbage is highly subjective, with some individuals or societies tending to discard things that others find useful or restorable. [3] The words garbage, refuse, rubbish, trash, and waste are generally treated as interchangeable when used to describe "substances or objects which the holder discards or intends or is required to discard". [4] [5] Some of these terms have historic distinctions that are no longer present. In the 1880s, material to be disposed of was divided into four general categories: ashes (derived from the burning of coal or wood), garbage, rubbish, and street-sweepings. [6] This scheme of categorization reduced some of these terms to more specific concepts:
Garbage, the technical term for putrescent organic matter such as kitchen or food scraps, was fed to pigs and other livestock or boiled down in a process known as "rendering," to extract fats, oils, and greases for manufacturing lubricants, or allowed to dry to become commercial fertilizer. Rubbish, a broad category of dry goods including boxes, bottles, tin cans, or virtually anything made from wood, metal, glass, and cloth, could be transformed into new consumer products through a variety of reclamation methods. [6]
The distinction between terms used to describe wet and dry discarded material "was important in the days when cities slopped garbage to pigs, and needed to have the wet material separated from the dry", but has since dissipated. [7]
In urban areas, garbage of all kinds is collected and treated as municipal solid waste; garbage that is discarded in ways that cause it to end up in the environment, rather than in containers or facilities designed to receive garbage, is considered litter. Litter is a form of garbage that has been improperly disposed of, and which therefore enters the environment. [8] Notably, however, only a small fraction of garbage that is generated becomes litter, with the vast majority being disposed of in ways intended to secure it from entering the environment. [7]
Humans have been creating garbage throughout history, beginning with bone fragments left over from using animal parts and stone fragments discarded from toolmaking. [9] The degree to which groups of early humans began engaging in agriculture can be estimated by examining the type and quality of animal bones in their garbage. [9] Garbage from prehistoric or pre-civilization humans was often collected into mounds called middens, which might contain things such as "a mix of discarded food, charcoal, shell tools, and broken pottery". [10]
Dumpster diving is salvaging from large commercial, residential, industrial and construction containers for unused items discarded by their owners but deemed useful to the picker. It is not confined to dumpsters and skips specifically and may cover standard household waste containers, curb sides, landfills or small dumps.
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
Post-consumer waste is a waste type produced by the end consumer of a material stream; that is, where the waste-producing use did not involve the production of another product.

The Tucson Garbage Project is an archaeological and sociological study instituted in 1973 by Dr. William Rathje in the city of Tucson in the Southwestern American state of Arizona. This project is sometimes referred to as the "garbology project".
William Laurens Rathje was an American archaeologist. He was professor emeritus of anthropology at the University of Arizona, with a joint appointment with the Bureau of Applied Research in Anthropology, and was consulting professor of anthropological sciences at Stanford University. He was the longtime director of the Tucson Garbage Project, which studied trends in discards by field research in Tucson, Arizona, and in landfills elsewhere, pioneering the field now known as garbology.
Garbology is the study of modern refuse and trash as well as the use of trash cans, compactors and various types of trash can liners. It is a major source of information on the nature and changing patterns in modern refuse, and thereby, human society. Industries wishing to demonstrate that discards originating with their products are important in the trash stream are avid followers of this research, as are municipalities wishing to learn whether some parts of the trash they collect has any salable value.
Litter consists of waste products that have been discarded incorrectly, without consent, at an unsuitable location. The word litter can also be used as a verb: to litter means to drop and leave objects, often man-made, such as aluminum cans, paper cups, food wrappers, cardboard boxes or plastic bottles on the ground, and leave them there indefinitely or for other people to dispose of as opposed to disposing of them correctly.
Illegal dumping, also called fly dumping or fly tipping (UK), is the dumping of waste illegally instead of using an authorized method such as curbside collection or using an authorized rubbish dump. It is the illegal deposit of any waste onto land, including waste dumped or tipped on a site with no license to accept waste. The United States Environmental Protection Agency developed a “profile” of the typical illegal dumper. Characteristics of offenders include local residents, construction and landscaping contractors, waste removers, scrap yard operators, and automobile and tire repair shops.
A bin bag, rubbish bag, garbage bag, bin liner, trash bag or refuse sack is a disposable bag used to contain solid waste. Such bags are useful to line the insides of waste containers to prevent the insides of the receptacle from becoming coated in waste material. Most bags today are made out of plastic, and are typically black, white, or green in color.
Marine debris, also known as marine litter, is human-created waste that has deliberately or accidentally been released in a sea or ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping. Naturally occurring debris, such as driftwood and drift seeds, are also present. With the increasing use of plastic, human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10%) and majority of large plastic in the oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish, seabirds, marine reptiles, and marine mammals, as well as to boats and coasts.
Garbage is an unwanted or undesired material or substance discarded by residents. The term is often used interchangeably with municipal solid waste.
A waste container, also known as a dustbin, garbage can, and trash can, is a type of container that is usually made out of metal or plastic. The words "rubbish", "basket" and "bin" are more common in British English usage; "trash" and "can" are more common in American English usage. "Garbage" may refer to food waste specifically or to municipal solid waste in general.
Kerbside collection or curbside collection is a service provided to households, typically in urban and suburban areas, of collecting and disposing of household waste and recyclables. It is usually accomplished by personnel using specially built vehicles to pick up household waste in containers that are acceptable to, or prescribed by, the municipality and are placed on the kerb.
The waste management in Switzerland is based on the polluter pays principle. Bin bags are taxed with pay-per-bag fees in three quarters of the communes. The recycling rate doubled in 20 years due to this strategy. The recycling rate for municipal solid waste exceeds 50 percent.
Waste management in Japan today emphasizes not just the efficient and sanitary collection of waste, but also reduction in waste produced and recycling of waste when possible. This has been influenced by its history, particularly periods of significant economic expansion, as well as its geography as a mountainous country with limited space for landfills. Important forms of waste disposal include incineration, recycling and, to a smaller extent, landfills and land reclamation. Although Japan has made progress since the 1990s in reducing waste produced and encouraging recycling, there is still further progress to be made in reducing reliance on incinerators and the garbage sent to landfills. Challenges also exist in the processing of electronic waste and debris left after natural disasters.
Waste are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
Carl Abraham Zimring is an American historian and professor at the Pratt Institute, known for his work on discard studies. With William Rathje, he edited The Encyclopedia of Consumption and Waste: The Social Science of Garbage. His books include Cash for Your Trash: Scrap Recycling in America, Clean and White: A History of Environmental Racism, and Aluminum Upcycled: Sustainable Design in Historical Perspective.
China's waste import ban, instated at the end of 2017, prevented foreign inflows of waste products. Starting in early 2018, the government of China, under Operation National Sword, banned the import of several types of waste, including plastics. The ban has greatly affected recycling industries worldwide, as China had been the world's largest importer of waste plastics and processed hard-to-recycle plastics for other countries, especially in the West.
New York City's waste management system is a refuse removal system primarily run by the New York City Department of Sanitation (DSNY). The department maintains the waste collection infrastructure and hires public and private contractors who remove the city's waste. For the city's population of more than eight million, The DSNY collects approximately eleven thousand tons a day of garbage, including compostable material and recycling.
