DEVELOPMENT OF INDICATORS TO ASSESS THE RESILIENCE POTENTIAL OF WASTE PICKER ORGANIZATIONS: AN APPROACH IN THE LIGHT OF RESILIENCE ENGINEERING

Abstract

The National Solid Waste Policy (PNRS) approved through Law No. 12,305, of August 2, 2010, established the Selective Collection (CS) as an instrument, being operationalized through the organizations (cooperatives/associations) of recyclable material collectors. In this sense, cooperatives are part of the recycling chain, subsidizing several production chains. These organizations represent a complex and dynamic system, where numerous interactions occur between its elements, which may present instabilities and the occurrence of unwanted events whose resilience can be affected. The ability to withstand the different pressures and threats must be developed in order to maintain the operability of the system under adversity. Anticipating, in the sense of mitigating or eliminating the risk/danger, brings a more resilient performance. Indicators that assess resilience potential can be a strategic tool for improving resilience. The objective of this research was to develop indicators to assess the resilience potential of waste picker organizations. To this end, the main approach was used the Delphi technique (associated with the concepts arising from resilience engineering established by Hollnagel (2012). A preliminary 33 indicators were suggested, which, after two rounds and due changes according to the method, were considered relevant and consensus was reached for a total of 21 indicators, which include the dimensions of the work, the process environment. These indicators were associated with the following skills: responding, monitoring, learning and anticipating, and the Likert scale was assigned to grade the indicators, constituting the Resilience Analysis Grid – RAG.
