  • Lower exposure to energy price fluctuations
  • Greater profitability with no added primary energy

Recovering industrial waste heat is a proven way to reduce emissions and comply with legal standards – like those in the EnEfG.

Your benefits:

  • Reduced energy demand and CO₂ emissions
  • Compliance with regulations
  • Clear progress toward ESG targets

Forward-looking heat recovery pays off. Customers value sustainability, and early adopters strengthen their market position.


Your benefits:

  • A reputation for innovation
  • Future-ready infrastructure
  • Lower energy costs = higher margins

Investments in waste heat recovery are subsidized – for example, under the BAFA EEW program. ENGIE handles the process from start to finish:

  • Confirming eligibility
  • Preparing all applications
  • Documenting savings over time

Frequently asked questions about industrial waste heat recovery

What is industrial waste heat?
It’s the heat released by systems like compressors, ovens, cooling equipment, exhaust air or compressed air systems.

When will the project pay for itself?
Typically within 3 to 6 years – even faster with subsidies.

Which industries benefit the most?
Any sector with continuous waste heat: metal processing, plastics, food production, chemicals, paper, and more.

How can waste heat be reused?
We start with a site analysis. If the heat and demand align in time, we design and implement customized solutions.

Are savings guaranteed?
Yes. We offer contractually secured savings – and if targets aren't met, we cover the difference.
