Sustainable development (SD) presents three pillars: environment, equality, and economy. Many scholars agree that circular economy (CE) currently displays a social gap, as most studies so far focus mostly on economic aspects and, occasionally, environmental too. Although some developed countries and especially the EU heavily promote it, there is little possibility of developing countries accepting CE unless it can fill what it is lacking. This study suggests the use of Schlosberg’s tripartite environmental justice (EJ) perspective to complete the concept of CE, bringing it closer to that of SD. Due to their significant contribution to both circularity and the environment, and, likewise, due to their poor social conditions, this paper focuses on the social group of WPs, mainly in Brazil. After conducting 19 semi-structured interviews, EJ was applied to the case of the Ecopoints in Fortaleza (northeastern Brazil) and each element—recognition, distribution, and participation—detected conflicts, such as underappreciation, continuously reduced access to recyclables, distrust, and miscommunication. If CE is successful in LMCs, it will heavily rely on WPs. The analysis suggests that it is necessary to recognize their contributions in order to value their work and consequently, promote their social inclusion.
