After several years of remote audits, Herr Klaus Mackenbrock returned to visit Nuova Gandiplast in person on September 11-12-13, 2023. The visit thus made possible the on-site audit for the surveillance of the "Blauer Engel" certification. Klaus was able to learn about the company's progress in plastic regeneration, the environmental performances of recent years, and two visits to plants for the collection and selection of raw materials used by Nuova Gandiplast.
