San Francisco has a 47-acre recycling and recovery center at the dump, where more than 100 tons or trash arrive daily, and for decades, artists have special scavenging privileges to rework the discarded things as art objects.

Acoustic Locator,  2012,  Terry Berlier
metal wheels, galvanized metal, steel, wood column, wood shelves, airline tie-down strapping

Impala,  2007,  Nemo Gould 

made from an electric sander, band saw blade wheels, projector flywheel, vacuum cleaner handles, meat grinder, motorcycle clutch lever, scavenged antlers, garlic press, conduit cover, and cheese slicers

the resulting creativity from dozens of Artists In Residence was on full display as 2,000 people attended the opening of a free exhibition featuring 35 years of artwork—a retrospective embodying the phrase ‘trash to treasure’
