Hitachi Zosen Inova was founded in 1933 as “L. von Roll Bamag Aktiengesellschaft”. It was originally a department of “Gesellschaft der Ludwig von Roll’schen Eisenwerke”, a steel mill and foundry that dates back to 1823. The purpose of the new department was to focus on thermal waste treatment. Six years later, it built the first turnkey plant for the Dutch city of Dordrecht.In its first few years, the company relied on several licenses to construct plants with technologies that were then state of the art. But from the very beginning, the company also developed proprietary and improved technologies. Subsequently, it repeatedly established milestones with its own designs, in the domain of thermal waste treatment, including the reciprocating grate, advanced methods for flue gas purification, and processes for the treatment of residues.
