Waste Picker Organizations are the fundamental link in the integrated management of urban solid waste, and they play a key social, economic, and environmental role. The main activity performed by Waste Picker Organizations is to insert materials in the productive cycle, thereby promoting a circular economy. However, due to the financial dependence on the public sector as the main economic source, and difficulties in self-management, Brazilian organizations do not achieve a competitive position in the recycling market. In this study we aimed to strengthen the Brazilian Waste Picker Organizations as solidarity economy companies throughout the application of corporate governance tools as to provide conditions to make them efficient in the recycling market and in the management of solid urban waste. The methodology was developed in three stages: identification of the Operating Activities of Waste Picker Organizations (Stage 1); hierarchization of the Operating Activities according to criteria that influence market efficiency (Stage 2); and creation of applicable reference models (Stage 3). According to the main results, the development of reference models, the hierarchical order of the Operating Activities, and the modeled processes indicated that the main activities that influence the market efficiency are selective collection, reception of the dry solid recyclable waste, sorting, pressing, baling, and the commercialization of selected waste.
拾荒者组织是城市固体废物综合管理的基本环节，它们在社会、经济和环境方面发挥着关键作用。拾荒者组织的主要活动是将材料插入生产周期，从而促进循环经济。然而，由于财政上依赖公共部门作为主要经济来源，以及自我管理的困难，巴西的组织在回收市场上无法获得竞争地位。在这项研究中，我们旨在通过应用公司治理工具来加强巴西拾荒者组织作为团结经济公司的地位，为它们在回收市场和城市固体废物管理方面的效率提供条件。该方法分三个阶段进行：确定拾荒者组织的运营活动（第 1 阶段）；根据影响市场效率的标准对运营活动进行层次化（第 2 阶段）；以及创建适用的参考模型（第 3 阶段）。根据主要结果，参考模型的开发、运营活动的层次顺序以及建模过程表明，影响市场效率的主要活动是选择性收集、干可回收废物的接收、分类、压缩、打包和选定废物的商业化。
