Recent evolution of the informal recycling sector in Argentina within the 'popular economy': Measuring its impact through a case study in Tandil (Buenos Aires).

The integration of the informal recycling sector into formal waste management systems is imperative to the implementation of the circular economy in the Global South. In Argentina, after the 2001 crisis, some large cities such as Buenos Aires greatly improved their informal recycling sector integration. In medium-size cities from the rest of the province, this was not the case. However, the formation of a national coalition between different sectors of what is now called the 'popular economy' forced the enactment, in the context of a new crisis, of a Social Emergency Law, which includes a Complementary Social Salary equivalent to half the minimum wage, among its main features. In this paper, we recap these recent changes and we use the InteRa framework in a case study to measure how, along with academic and civil society support actions, they influenced the informal recycling sector integration in an intermediate city of Buenos Aires province. Our results show that the inclusion of the informal recycling sector improved rapidly after the availability of the Complementary Social Salary. Nevertheless, we registered a hard-to-overcome stagnation in some indicators of the InteRa framework, related to the weak engagement of the local municipal government with the informal recycling sector. Importantly, the advent of the Complementary Social Salary was not reflected in any indicator because there is no specific action related to this aspect in the InteRa framework. This may give an insight into future methodology improvement.
