Clariant was once again able to record a significant reduction of its energy consumption in 2016. All forms of energy, such as electricity, heat, cold, steam, as well as natural gas, nitrogen or desalinated water are included here. Almost all of the savings were the result of the measures initiated by the energy management program eWATCH. eWATCH is a group-wide systematic, efficient and coordinated energy management program. The program permanently records the whole energy consumption, analyzes the savings potentials and enables the continuing usage optimization of the machines. Plants are being planned and utilized in the production process in such a way that they can be optimized continuously to achieve the best efficiency level of each individual usage. The lessons learned here help in the performance-optimized design of plants and in the selection of efficient components. Not only is eWATCH very interesting from an ecological point of view but also from an economic point of view because the program allows the evaluation of the cost-benefit ratio between investments and energy savings.
