1. Reminders about a waste sorting center

Preliminary remark: this article is a testimonial based on real-life experience. However, all the figures given are for illustrative purposes and to enable rigorous reasoning. They are not an accurate representation of the waste industry, which varies enormously from one town to another and from one region to another.

On the other hand, processes and presentations have been greatly simplified so as not to burden the reader with details that are unnecessary to the proposed demonstration.

Finally, for reasons of confidentiality, the amounts in euros have been replaced by "market" averages found on the Internet.
