Franz Neubacher †


We pay tribute to Franz, who died in a tragic traffic accident in the summer of 2018, for his extraordinary dedication for the company. In his visionary, creative, persistent and pragmatic way he had a major impact on the reduction of environmental pollution and the setting of high standards in Austria. He was also committed to improving waste management through specific projects worldwide. We will keep him in loving memory, as a good friend, highly experienced colleague, partner and founder of our company.
