Brazil is the second largest producer of electronic waste in the Americas, with a
production that grows each year and only 10 percent of it is properly treated. Additionally,
Brazil does not have its own technology for treating printed circuit boards, a key
component present in this type of waste. Currently, Brazil does not have an industrial
plant dedicated to this extractive activity from electronic waste, with most of its treatment
carried out abroad. The research hypothesis of this manuscript is that universities and
their communities could develop raw material sources for such extraction processes and,
therefore, deserve attention for the creation of collection points and partnerships. In this
context, it is necessary to understand the behavior of this community in relation to the
acquisition, storage and disposal of electronic equipment, as well as information on issues
related to the management and recycling of electronic waste. Additionally, a conceptual
treatment route was created based on the integration of technologies described in the
literature. After creating the route design, a mass and energy balance was carried out,
considering two base cases of printed circuit boards as raw material: A) Electronic waste
in general; B) using cell phones only. For both cases, the treatment of 2 t/h was
considered. It was determined that the studied group has more than 16.96 million cell
phones in hibernation, in addition to other equipment, with an estimated inventory value
of 67.45 million dollars for the studied group in the metropolitan region of Rio de Janeiro.
If extrapolated to all of Brazil, it could reach 797.50 million dollars for the studied group.
an internal rate of return of 141.6 percent and 3990.7 percent for case A and B, respectively, and net
present value of USD 44,834,616 and USD 3,215,300,083 for case A and B, respectively.
Additionally, it was determined that case A is highly sensitive to occupancy rate variation.
In this context, this research has the potential to help in the creation of the first Brazilian
industrial plant dedicated to the recycling of printed circuit boards, as well as to
understand the key variables for the processing of these components. Additionally, the
project presents the investment necessary for the creation of the plant, being crucial
information for potential investors.
