The aim of the Energy Efficiency Check is to identify measures for reducing energy consumption and to conduct an economic and technical evaluation of these. This is done systematically using a wide spectrum of method-based tools, ranging from simple operational improvements in production to the complex routing of heat flows and optimization of energy generation. Improvement in efficiency is also tested by using innovative technologies, for instance. Further measures range from better coordinated supply chains to the optimization of workflows. The extensive, in-depth technological know-how of Bayer Technology Services, combined with the customer’s operational knowledge, enables identification of a comprehensive catalogue of measures.
