While here in Chicago we volunteered at Working Bikes. Here they took in donations of old bicycles and then repurposed them. Old bikes are now Art, machines, gizmos and much more. Tires are made into other things such as belts and ties. The bikes that can be salvaged are fixed up and then given to local underprivileged kids in Chicago and some are shipped to developing countries overseas.
