Abstract
Cooperatives of waste pickers play a critical role in municipal solid waste management, contributing to public health, sanitation, and the environment by promoting resource circulation and reducing the amount of recyclable waste disposed of in landfills. Despite this, the majority of cooperatives lack an organized physical infrastructure and operational protocols for integrated waste management, which includes the stages of sorting, classification, processing, and marketing recyclable waste. In this work, an optimized survey was developed to assist waste pickers’ cooperatives in self-assessing their social, environmental, and economic performances. A questionnaire with nine dimensions was developed and automated to connect 16 driving forces (D), 74 pressure indicators (P), 23 states (S), 35 impacts (I), and 38 responses (R). The only action required was to choose each pressure indicator and apply the appropriate score level based on the cooperative's data analysis. The procedure eliminates subjective interpretation and identifies all indicators that require further consideration and discussion. As a result, the cooperative is able to propose highly targeted improvement measures. To demonstrate the benefits of the tool, the survey was applied in a waste picker's cooperative in a municipality in Brazil.
