Dumpster

A dumpster is a type of mobile garbage bin designed to be brought and taken away by a special truck. The word is a genericized trademark of Dumpster, an American brand name for a specific design. Generic usage of dumpster is also common in Australia, although Dumpster is not an established brand there.

The word "dumpster", first used commercially in 1936, 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. The containers were called Dumpsters, a portmanteau 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, but today it is often used as a genericized trademark.

In British and Australian English, the terms wheelie bin and skip are more commonly used (although they are not perfect synonyms). In some other countries the more descriptive term frontloader container is often used, either in one or two words.

The main purpose of a dumpster is to store rubbish until it is emptied by a garbage truck and disposed of. Dumpsters can be used for all kinds of waste, or for recycling purposes. Most dumpsters are emptied weekly by a hired rubbish removal service.

Many businesses, apartment buildings, schools, offices, and industrial sites have one or more dumpsters, generally ranging from 2 to 6 cubic yards, to store the waste that they generate. 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 then lift the prongs and the dumpster, eventually flipping the dumpster upside-down and emptying its contents into the truck's hopper (storage compartment).
