The German company SUPREN GmbH has a strong background and industrial experience in process design, simulation and energy optimization. Based on the complementary exploration of long-term, comprehensive in-house knowledge and the use of sophisticated commercial CAPE tools, most sustainable process designs are identified systematically guided by insights obtained from assessments of the process performance. These assessments are conducted from a whole-process perspective and are of a multi-criterial nature, hence covering economic, ecological and social viewpoints.
