Reducing energy consumption with waste heat

Waste Heat

Many industrial companies generate waste heat that can be used to generate energy and increase energy efficiency. As part of the Efficiency Act, companies with an annual energy consumption of more than 2.5 GWh are obliged to record and report the waste heat situation on site. In addition, companies are obliged to avoid and use waste heat recovery.

Waste Heat Utilization and Heat Integration

By using their waste heat efficiently, companies can not only meet legal requirements but also achieve significant cost savings. We support you in identifying the right combination of heat sources and sinks and in mastering the high level of complexity caused by the interaction of different technologies.

Industrial waste heat offers outstanding opportunities for energy recovery and therefore energy efficiency potential for companies. Recording and evaluating the combination of heat sources and heat sinks on site is complex. We support you with our systematic approach.

  • What new obligations and requirements arise in connection with waste heat and the Energy Efficiency Act?
  • How do we implement the requirements of the Energy Efficiency Act in our company on time?
  • How do you identify and evaluate waste heat sources?
  • Which technologies and processes are best suited to waste heat recovery in our specific production environment?
  • How can we ensure that our waste heat recovery strategy is effective and sustainable in the long term?

Food Pinch research project

Energy saving with software-based pinch control

In the Food Pinch research and development project, ÖKOTEC and RWTH Aachen LTT are developing solutions to intelligently connect heat sources and sinks in the food industry. An automated control system makes it possible to respond to the dynamic processes in food production and save energy in the long term.
