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. All three trademarks have since either been expired or cancelled.

then lift the prongs and the dumpster, eventually flipping the dumpster upside-down and emptying its contents into the garbage truck hopper (storage compartment). Other dumpsters are smaller and are emptied by rear-loading trucks. Ninety-five gallon 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. Mobile construction dumpsters are dumpster trailers called "roadrunners", and are commonly used on smaller remodeling jobs or for garage or lawn clean-outs.

Roll-off/containers/dumpsters/opentop containers are just a few of the names given to these large capacity receptacles. 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 place these containers in a relatively unobtrusive position. Roll-off dumpster are available in a variety of sizes to fit different situations. The size you need will generally depend on the following three factors: 1) Volume of Material, 2) Type of Material 3) Location or Placement of the dumpster. For example, heavy materials like bricks or stones should be in smaller dumpster so the container does not exceed weight limits for transportation.

Dumpster diving

Dumpster diving involves persons voluntarily climbing into a dumpster to 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 as dumpster diving.
