摘要

The circular economy (CE) model has become highly relevant in recent years, with the electronics industry being one of the sectors that has considered its application. Despite only a limited amount of literature being available on waste electric and electronic equipment (e-waste) in Mexico, the Mexican Government, academic institutions, and electronics industry have coordinated efforts to implement the CE in the country. This study evaluates the current technical and economic situation of cellphone e-waste generated in Mexico by surveying and analyzing the main actors that influence the management of this waste and using a material flow analysis. Extensive fieldwork was conducted in order to quantify the extent of cellphone e-waste processing in both formal and informal channels. The study of printed circuit boards in cellphones shows that the total value of cellphone e-waste materials ranges between $11.277 and $12.444 million USD per year in Mexico. However, a value of only $0.677 million USD is recycled through formal channels. After characterizing the remanufacturing and recycling CE loops, we conclude that the potential for improvement and advancing towards a CE model is significant
