Roll-off container

The word "dumpster", first used commercially in 1936,[5] came from the Dempster-Dumpster system of mechanically loading the contents of standardized containers onto garbage trucks, which was patented by Dempster Brothers in 1935.[6][7] The containers were called Dumpsters, a blending of the company's name with the word dump. The Dempster Dumpmaster, which became the first successful front-loading garbage truck that used this system, popularized the word.

The word dumpster has had at least three trademarks associated with it by Dempster Brothers,[8][9][10] but today it is often used as a genericized trademark. All three trademarks have since either been expired or cancelled.[11]

A dumpster is sometimes considered synonymous with a skip.[4] However, there are functional differences between them. A skip is intended to tát be loaded onto a vehicle and transported to tát another location. Dumpsters, on the other hand, have their contents emptied into a special vehicle, and are seldom moved from their locations.[12]


A dumpster is unloaded by a front-loading garbage truck

The main purpose of a dumpster is to tát store garbage until it is emptied by a garbage truck for disposal.[12] Dumpsters can be used for all kinds of waste, or for recycling purposes.

Most dumpsters are emptied by front-loading garbage trucks. These trucks have large prongs on the front which are aligned and inserted into arms or slots on the dumpster. Hydraulics lift the prongs and the dumpster, eventually flipping the dumpster upside-down and emptying its contents into the garbage truck's hopper (storage compartment). Other dumpsters are smaller and are emptied by rear-loading trucks. Dumpsters are typically emptied outside of peak traffic hours.[12] The frequency at which dumpsters are emptied varies from community to tát community, often ranging from daily to tát weekly, depending on the volume of trash generated.[13]


Many businesses, apartment buildings, schools, offices, and industrial sites have one or more dumpsters, generally ranging from 0.5 to tát 8 cubic yards (0.38 to tát 6.12 m3), to tát store the waste that they generate.[14]

Waste storage containers can be made from a wide variety of materials, including steel and fiberglass.[14] Plastic dumpsters became available in the 1970s.[15]

In the United States, 96-US-gallon (0.36 m3) dumpsters (also known as "roll carts" or "toters") are used by small businesses and homes where a normal bin would be too small, but a regular dumpster would be too large. These are emptied by rear-loading trucks or by side-loading trucks purpose-built for emptying roll carts of this and smaller sizes.[16]

Roll-offs, sometimes called roll-off dumpsters or containers or open-top dumpsters or containers, are larger dumpster trailers ranging from 10 to tát 45 cubic yards (7.6 to tát 34.4 m3) and are used at demolition sites, clean-outs, renovations, construction sites, factories, and large businesses. These containers are normally carried by very large trucks with hydraulic arms which load and unload the containers with ease, thus allowing these trucks to tát place these containers in a relatively unobtrusive position.

Roll-off dumpsters are available in a variety of sizes to tát fit different situations. The size needed will generally depend on three factors: volume of material, type of material, and location or placement of the dumpster. For example, heavy materials lượt thích bricks or stones should be placed in smaller dumpsters sánh the loaded container does not exceed weight limits for transportation.

Dumpster diving[edit]

Dumpster diving involves persons voluntarily climbing into a dumpster to tát find valuables, such as discarded metal scrap, or simply useful items, including food and used clothing. It can also be a method of investigation (e.g., looking for discarded financial records, private papers, or evidence of a crime). Going through garbage containers that are not strictly speaking dumpsters is nevertheless often referred to tát as dumpster diving.
