Dumpster diving (also totting, skipping, skip diving or skip salvage,) is salvaging from large commercial, residential, industrial and construction containers 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.
Different terms are used to refer to different forms of this activity. For picking materials from the curbside trash collection, expressions such as curb shopping, trash picking or street scavenging are sometimes used. When seeking primarily metal to be recycled, one is scrapping. When picking the leftover food from traditional or industrial farming left in the fields one is gleaning.
People dumpster dive for items such as clothing, furniture, food, and similar items in good working condition. Some people do this out of necessity due to poverty, while others do so professionally and systematically for profit.
The term "dumpster diving" emerged in the 1980s, combining "diving" with "dumpster", a large commercial trash bin. The term "Dumpster" itself comes from the Dempster Dumpster, a brand of bins manufactured by Dempster Brothers beginning in 1937. "Dumpster" became genericized by the 1970s. According to the Oxford English Dictionary, the term "dumpster diving" is chiefly found in American English and first appeared in print in 1983, with the verb "dumpster-dive" appearing a few years later. In British English, the practice may be known as "skipping", from skip, another term for this type of container.
The term "binner" is often used to describe individuals who collect recyclable materials for their deposit value. For example, in Vancouver, British Columbia, binners, or bottle collectors, search garbage cans and dumpsters for recyclable materials that can be redeemed for their deposit value. On average, these binners earn about $40 a day for several garbage bags full of discarded containers.
The karung guni, Zabbaleen, the rag and bone man, waste picker, junk man or bin hoker are terms for people who make their living by sorting and trading trash. A similar process known as gleaning was practised in rural areas and some ancient agricultural societies, where the residue from farmers' fields was collected.
The activity is performed by people out of necessity in the developing world. Some scavengers perform in organized groups, and some organize on various internet forums and social networking websites. By reusing, or repurposing, resources destined for the landfill, dumpster diving is sometimes considered to be an environmentalist endeavor, and is thus practiced by many pro-green communities. The wastefulness of consumer society and throw-away culture compels some individuals to rescue usable items (for example, computers or smartphones, which are frequently discarded due to the extensive use of planned obsolescence in the technology industry) from destruction and divert them to those who can make use of the items.
A wide variety of things may be disposed while still repairable or in working condition, making salvage of them a source of potentially free items for personal use, or to sell for profit. Irregular, blemished or damaged items that are still otherwise functional are regularly thrown away. Discarded food that might have slight imperfections, near its expiration date, or that is simply being replaced by newer stock is often tossed out despite being still edible. Many retailers are reluctant to sell this stock at reduced prices because of the risks that people will buy it instead of the higher-priced newer stock, that extra handling time is required, and that there are liability risks. In the United Kingdom, cookery books have been written on the cooking and consumption of such foods, which has contributed to the popularity of skipping. Artists often use discarded materials retrieved from trash receptacles to create works of found objects or assemblage.
Students have been known to partake in dumpster diving to obtain high tech items for technical projects, or simply to indulge their curiosity for unusual items. Dumpster diving can additionally be used in support of academic research. Garbage picking serves as the main tool for garbologists, who study the sociology and archeology of trash in modern life. Private and government investigators may pick through garbage to obtain information for their inquiries. Illegal cigarette consumption may be deduced from discarded packages.
Arguments against garbage picking often focus on the health and cleanliness implications of people rummaging in trash. This exposes the dumpster divers to potential health risks, and, especially if the dumpster diver does not return the non-usable items to their previous location, may leave trash scattered around. Divers can also be seriously injured or killed by garbage collection vehicles; in January 2012, in La Jolla, Swiss-American man Alfonso de Bourbon was killed by a truck while dumpster diving. Further, there are also concerns around the legality of taking items that may still technically belong to the person who threw them away (or to the waste management operator), and whether the taking of some items like discarded documents is a violation of privacy. In general a legal concept called abandonment of property covers this question of the subject of ownership of property that is disposed of.
Discarded billing records may be used for identity theft. As a privacy violation, discarded medical records as trash led to a $140,000 penalty against Massachusetts billing company Goldthwait Associates and a group of pathology offices in 2013 and a $400,000 settlement between Midwest Women's Healthcare Specialists and 1,532 clients in Kansas City in 2014.
Since dumpsters are usually located on private premises, divers may occasionally get in trouble for trespassing while dumpster diving, though the law is enforced with varying degrees of rigor. Some businesses may lock dumpsters to prevent pickers from congregating on their property, vandalism to their property, and to limit potential liability if a dumpster diver is injured while on their property.
Police searches of discarded waste as well as similar methods are also generally not considered violations; evidence seized in this manner has been permitted in many criminal trials. In the United States this has been affirmed by numerous courts including and up to the Supreme Court, in the decision California v. Greenwood. The doctrine is not as well established in regards to civil litigation.
Companies run by private investigators specializing in such techniques have emerged as a result of the need for discreet, undetected retrieval of documents and evidence for civil and criminal trials. Private investigators have also written books on "P.I. technique" in which dumpster diving or its equivalent "wastebasket recovery" figures prominently.
In 2009, a Belgian dumpster diver and eco-activist nicknamed Ollie was detained for a month for removing food from a garbage can, and was accused of theft and burglary. On February 25, 2009, he was arrested for removing food from a garbage can at an AD Delhaize supermarket in Bruges. Ollie's trial evoked protests in Belgium against restrictions from taking discarded food items.
In Ontario, Canada, the Trespass to Property Act—legislation dating back to the British North America Act of 1867—grants property owners and security guards the power to ban anyone from their premises, for any reason, permanently. This is done by issuing a notice to the intruder, who will only be breaking the law upon return. Similar laws exist in Prince Edward Island and Saskatchewan. A recent case in Canada, which involved a police officer who retrieved a discarded weapon from a trash receptacle as evidence, created some controversy. The judge ruled the policeman's actions as legal although there was no warrant present, which led some to speculate the event as validation for any Canadian citizen to raid garbage disposals.
In Germany, dumpster diving is referred to as "containern", and a waste container's contents are regarded as the property of the container's owner. Therefore, taking items from such a container is viewed as theft. However, the police will routinely disregard the illegality of garbage picking since the items found are generally of low value. There has only been one known instance where people were prosecuted. In 2009 individuals were arrested on assumed burglary as they had surmounted a supermarket's fence which was then followed by a theft complaint by the owner; the case was suspended.
In the United States, the 1988 California v. Greenwood case in the U.S. Supreme Court held that there is no common law expectation of privacy for discarded materials. There are, however, limits to what can legally be taken from a company's refuse. In a 1983 Minnesota case involving the theft of customer lists from a garbage can, Tennant Company v. Advance Machine Company (355 N.W.2d 720), the owner of the discarded information was awarded $500,000 in damages.

Dumpster diving is practiced differently in developed countries than in developing countries.
- Food. In many developing countries, food is rarely thrown away unless it is rotten as food is scarce in comparison to developed nations. In countries like the United States, where 40 to 50 percent of food is wasted, the trash contains a lot more food to gather. In many countries, charities collect excess food from supermarkets and restaurants and distribute it to impoverished neighbourhoods. Trash pickers, Karung guni, Zabaleen, and rag and bone men in these countries may concentrate on looking for usable items or scrap materials to sell rather than food items. In the United States, Canada, and Europe, some bakeries, grocery stores, or restaurants will routinely donate food according to a Good Samaritan Food Donation Act, but more often, because of health laws or company policy, they are required to discard food items by the expiration date, because of overstock, being overly ripened, spoiled, cosmetically imperfect, or blemished.
- Books and periodicals. As proof to publishing houses of unsold merchandise, booksellers will routinely remove the front covers of printed materials to render them destroyed prior to disposing of their remains in the garbage. Though readable, many damaged publications have disclaimers and legal notices against their existence or sale.
- Irregular or damaged goods. Offices, factories, department stores, and other commercial establishments may equally throw out non-perishable items that are irregular, were returned, have minor damages, or are replaced by newer inventory. Many items tend to be in such a state of disrepair or cosmetically flawed that they will require some work to make the items functionally usable. For this reason, employees will at times intentionally destroy their items prior to being discarded to prevent them from being reused or resold.
- Returned items. Manufacturers often find it cheaper to routinely discard items returned as defective under warranty instead of repairing them, although a device is often repairable or usable as a source of spare parts to repair other, similar discarded devices.
- School Supplies. At the end of each school year many people throw away perfectly useful supplies like pencils, pens, notebooks, art supplies.
- eWaste. Some consumer electronics are dumped because of their rapid depreciation, obsolescence, cost to repair, or expense to upgrade. Owners of functional computers may find it easier to dump them rather than donate because many nonprofit organizations and schools are unable, or unwilling, to work with used equipment Occasionally, vendors dispose of unsaleable, non-defective new merchandise as landfill. The Atari video game burial in Alamogordo, New Mexico after the North American video game crash of 1983 is a well-known example; a 2014 excavation recovered about 1300 games for curation as museum exhibits or auction.
- Clothing. While thrift stores routinely refuse used goods which they cannot cheaply and easily resell, the items which they do accept cost them nothing. There is therefore no shrinkage cost associated with discarding mendable garments, repairable appliances or even working donated items which are overstock or find no buyer after some arbitrary length of time.
- Metal. Sometimes waste may contain recyclable metals and materials that can be reused or sold to recycling plants and scrap yards. The most common recyclable metals found are steel and aluminum.
- Wood. Called urban lumberjacking, to salvage wood either for home heating, or home construction projects.
- Residential buildings. Clothing, furniture, appliances, and other housewares may be found at residential buildings.
- College dormitories. Items may be found at colleges with dormitories at the end of the semester when students throw away many items such as furniture, clothes and electronics.
In the 1960s, Jerry Schneider, using recovered instruction manuals from The Pacific Telephone & Telegraph Company, used the company's own procedures to acquire hundreds of thousands of dollars' worth of telephone equipment over several years until his arrest.
In October 2013, in North London, three men were arrested and charged under the 1824 Vagrancy Act when they were caught taking discarded food: tomatoes, mushrooms, cheese and cakes from bins behind an Iceland supermarket. The charges were dropped on 29 January 2014 after much public criticism as well as a request by Iceland's chief executive, Malcolm Walker.
