Recycling systems succeed when the people doing the work capture some of the value they create.
Recyclable material has value. The difficulty is that the value is captured far from the household and the collector who made recovery possible in the first place.
A coordinated exchange changes the economics. When handover is verified and logged, value can be credited back to the participant who created it, and recovery volumes become reportable rather than anecdotal.
That is the difference between an environmental campaign and an environmental system.
