Faced with health issues related to waste management, public policies to integrate the informal recycling sector have remained a minority. In Peru, since the Law of Wastepicker of 2009, district municipalities have to establish a waste selective collection service through the integration of informal wastepickers. Using concepts of formalization model and shared management, the aim of this work is to understand the application of this new legislation in Lima, the Peruvian capital marked by territorial fragmentation. Empirical research conducted in three districts enables us to see that the potential of shared management is underutilized and that the Law of Wastepicker cannot put an end to the informal sector of waste management alone.
