Aiming for the highest purity by sorting 50,000 tons of waste annually


Altem is a company for sorting household packaging waste based in Strasbourg, France. It is a sorting centre that is solely dedicated to the sorting and conditioning of household waste – in other words, selective collection. About 50,000 tons of waste are sorted at the facility each year, which corresponds to a population of approximately 800,000 inhabitants.

"The product we sort today will be different from the product we sort tomorrow. What we want to do with the robot is to follow this evolution and ensure that the robot can help us adapt to the different sorting operations that will have to be done in the future."

Guillaume Schroll,
in charge of Altem's sorting centre.

Efficient quality control of coloured PET


The ZenRobotics Fast Picker has been placed on the plastic sorting line for quality control of coloured PET. Fast Picker’s job is to extract residual contaminants so that the flow produced at the end of the line is the purest possible coloured PET.A

"Fast Picker is a product that gives us enough confidence in the future and in the various adaptations that we'll have to make according to the evolution of the waste flows entering the sorting centre."
