It isn't worth collecting. This is Earth orbit, not the ocean or some strip of land. The debris zooms around the planet on all kinds of trajectories and it's immensely difficult to match velocity and direction in order to capture it. It's worse than trying to collect machine gun bullets mid-flight that were fired from a rotating carousel by a guy with shaking hands... Some parts, like spent second rocket stages, present some value because they could be reused as wet-workshops [1]. Material value alone, however, doesn't justify the cost of capture in most cases.
