"The twenty-first-century world is a crowded one - one might think there's no room left for newly founded societies. But the disorder offers plenty of elbow room. There are many handsome places that people have abandoned in despair. Beirut was a quite lovely place once; Sarajevo had a great deal to recommend it. If a group of daring global investors offered to rebuild Kabul wholesale, they'd likely be met with open arms."

("TOMOROW NOW" - Bruce Sterling)

Anything unlikely, unexplored or abandoned, can become the ground

for new economies and innovative ideas.

Garbage is abandoned, unexplored (because it is abandoned), and unlikely (because it is unexplored). Garbage compacting machines that produce energy, or another material.
