SUMMARY:

The linear economy model used around the world (resource extraction – productionconsumption-
disposal) has placed an enormous burden on the environment and hampered its
self-recovery capacity, having environmental negative implications, and also economic and
social negative impacts. In this sense, the circular economy model (production-consumption –
reintroduction) figures as one of the attempts to slow down the impact that the linear model has
on the world. Despite the advances experienced in developed countries, developing countries
like Brazil face difficulties in making a shift to the circular economy model, either due to lack
of structure or knowledge, or because several decisions need to be taken, decisions that may
involve different decision-makers, their conflicting perspectives, and criteria. Thus, the
objective of this thesis was to propose models to support decision-making and negotiation that
would help various sectors in Brazil to make the transition to a circular economy more
assertively. In chapter 3, a group decision model is proposed to help segments of society to
identify and allocate responsibilities and costs for solid waste management. A case study in the
packaging sector is presented to validate the model. Therefore, in chapter 4, a multi-criteria
model of the individual decision is presented to help company managers to define which
strategies should be outsourced and which should be kept in-house as they were their
responsibilities. Two case studies in circular economy textile companies adopters and
incumbents were used to validate the model and to compare what the main nuances can emerge
from these two different business models, and, thus, generating insights that help adopters to
make better decisions about outsourcing strategies. Afterward, as many economic activities are
developed through the indiscriminate use of water that is a finite natural resource, in chapter 5,
a negotiation model is proposed to resolve conflicts in river basin committees on the
identification and allocation of circular strategies to minimize the pollution and water scarcity.
This model was also validated in a case study. The results of the application of the models
showed that the circular economy is an umbrella topic and that, regardless of the sector, size,
and/or activity in Brazil, this new model can be implemented bringing environmental,
economic, and social benefits.
