The waste as resource strategy is biomimicry: imitating nature for efficiency. In real ecology the waste or detritus of one creature is very often the food of another. Humans who adapt this strategy build industrial ecology so that waste disposal from one process is actually the resource inputs of another. This strategy is part of Natural Capitalism and is very strongly encouraged by a green tax shift or by Consumerium.
Accordingly, if we can turn cast-off junk into a healthy buying infrastructure we will all be better off than if we bought all its parts new.
