The legal foundations of waste picking have, however, received little scholarly attention. Surveys conducted with waste pickers from 5 cities (Bogotá, Pune, Belo Horizonte, Durban, Nakuru) find that existing, and often hostile, regulations and competition from new entrants are key concerns for the waste pickers. In this paper, I argue that a ny system of legal rules that tries to exclude the waste pickers from the waste value chain results in h igh transaction costs and risks further aggravating existing social injustices. Several inclusive property right regimes are conceivable, from waste picker ownership of waste to a res nullius (nobody’s property) regime complemented by a right of first possession . R es nullius create s incentives for the stake holders of waste to specialize in different segments of the collection and recycling chain. P o ssible drawbacks of this regime are dissipating rents because of open access to waste .engProperty rightsSolid wasteWaste pickersInformal economyresnulliusOne man’s trash is another man’s treasure: A comparative analysis of property rights in solid wasteworking paper
