Waste Sorting Quality Assessment

Stakeholders: Grupo Gestão; Serviço de Limpeza Urbana do Distrito Federal.

Problem: Lack of data about the efficiency of the waste sorting facilities (Galpões de Triagem) in the Federal District.

Context: After the closure of the dumsite in Brasília, the waste pickers are now working in the waste sorting facilities (Galpões de Triagem), where they sort and organize the recyclable waste to sell it later on. But the engineers and supervisors of their operation observe that much of the waste they reject (as non recyclable) is actually recyclable. Due to this "efficiency problem", a significant amount of the recyclable waste is being thrown away and sent to the landfill in Samambaia. Some estimate that more than 50% of the recyclables are being wasted, but nobody knows the exact percentage. Why? Because there are no processes for measuring quality. Therefore, there is a lack of data about the efficiency of the waste sorting facilities (Galpões de Triagem) in the Federal District. Two main questions appear:

- how can I continuously (established process) measure the amount of recyclables being wasted?

- how can I improve the operation in order to dramatically reduce the amount of recyclables being wasted?

Last semester (2.2019), a project was done to fathom the problem and possible solutions. Now is the time to go to the next level.

Objective: imagine you received the duty and power from the government to solve this problem and you will receive a budget at the end of the semester to implement your solutions (this can actually become true!!). How would you apply your knowledge and change the operation to solve this problem? Make your best project to be implemented.
