Final considerations
The marginalist economic assessment carried out in this article highlighted the existence of an optimal level
of recycling which is not the maximum. This is due to the difference between private costs and marginal

benefits, and social costs and marginal benefits, given the existence of market imperfections. Those
imperfections make the WEEE management in Brazil does not benefit from economies of scale being very
dependent on regulatory instruments for its operation [9-10-33].
Huisman, Schuelp et ap. and Zimmermann [16-18-20] provide information that enables the proposal of
strategy to explore the WEEE management taking maximum economic advantage through profit by selling
their components. The inclusion of RFID in WEEE management as a way to reach environmental goals at
lower costs and greater benefits to society enables the elimination of market imperfections in order to reach the
social optimum [23-24].
Even with government actions to correct those market imperfections, such as the application of Law
12,305/2010 in Brazil, these adjustments meet the learning curve involved with the practice of RL of WEEE
and their interfaces, especially with the environmental licensing generators, transporters and receptors of this
type of waste.
The knowledge of these learning curves should be the next step in search of full power operation efficiency
of reverse logistics of WEEE by inserting the RFID technology, in order to WEEE managers assist in the
measurement of costs and benefits that enable distributional issues intra and intergenerational pondering the
same depending on the chosen social values.
This complete assessment of social welfare variations, as shown here, has resulted in the better decision
making evoking the motto adopted by the German Energy Agency, "Effizienz entscheidet" (efficiency decide).
