Artist and environmental activist Oliver Bishop-Young's project "Skip Conversions" tried to find creative and often amusing ways of recycling unwanted products. One example was a dumpster, which he turned into a swimming pool, a skateboard ramp, a living room, a garden, and a campsite. More pictures at the link.

Nope, they just converted skips, which "A Noun" has already explained are garbage receptacles, commonly known to many as dumpsters.
I can honestly say I've never seen anyone throwing out a dumpster.
