SUMMARY:

Waste from electrical and electronic equipment – WEEE currently figures as one of the fastest growing municipal solid waste streams in Brazil and in the world. The sectoral agreement for the implementation of a reverse logistics system for Brazilian electrical and electronic products was established in 2019 and represented a relevant step towards the institutionalization of appropriate measures for the destination and treatment of WEEE from equipment placed in the domestic market. However, according to Green Eletron (2021), only 3% of WEEE generated in the country is reintroduced into formal value chains. In addition, the effects of the sectoral agreement are reactive to the waste generated in the post-consumption period. Thus, there are no provisions that discuss the design and manufacturing processes of electrical and electronic equipment. In this scenario, the circular economy has been receiving special attention among academics and professionals for promoting the closing of the life cycle of products and the creation of new business models that contribute to economic growth and sustainable development. The objective of this dissertation is to propose strategies to improve the national WEEE revaluation chain through the institutionalization of circular economy principles in the design and manufacturing phases of electrical and electronic equipment. To this end, an applied, exploratory and descriptive research was carried out, with a predominantly qualitative approach, divided into two stages. First, in the theoretical stage, an integrative literature review was performed based on the Methodi Ordinatio protocol. Subsequently, in the empirical stage, individual semi-structured interviews (n = 12) were conducted with stakeholders of the sectoral agreement for electrical and electronic equipment products. The inputs collected in the interviews enabled the use of the SODA (Strategic Options Development and Analysis) method of problem structuring, which provides for the elaboration of individual cognitive maps and subsequent aggregation into a single map from validation by the research participants. Finally, it was found that, starting from the concept of circular economy, there are different strategies of retention, addition and recovery of value that can be applied to improve the chain of revaluation of WEEE in Brazil. Despite the emphasis on the design and manufacturing phases of equipment, these strategies go through the revision of the normative framework, especially related to the taxation of material from the disassembly and separation processes.
