City wood

To take something that's overlooked and turn it into a product or service that has value to people in the marketplace - that's a special kind of innovation.

The "sharing economy" does that, i.e. turning unused assets into marketable assets.  Uber enables you to sell your free time as a driving service to people who need a ride. RelayRides enables you to rent your car (if it would otherwise be idle in your driveway) to a customer. 

Vancouver Urban Timberworks made a business out of a different overlooked resource. They provide free pickup of fallen city trees, which  they cut into timber and use to create custom projects for their clients. Trees that might have gone to landfill now become a valued wood creation for someone.
