What if the heat your factory throws away could be used to power your cooling needs? That’s the challenge RE-WITCH is taking on, and during our latest webinar, “The Coolest Cold from the Cleanest Heat,” we showcased how we’re making that vision real.
The webinar gave participants an inside look at the technologies, demo sites, and strategies behind RE-WITCH, an EU-funded project developing low-carbon industrial cooling and heating solutions powered by waste heat and renewables.
We introduced three core technology lines:
- Absorption systems using heat to deliver cooling, even at two different temperatures simultaneously
- Adsorption chillers with modular designs for flexibility and easier integration in existing factories
- Renewable energy through solar thermal
We also explored hybrid systems that combine thermal and electric input to deliver both heating and cooling in one cycle. A smart solution already being tested in a Spanish dairy plant.
But innovation doesn’t stop at the machine level. We walked through how the project is planning the integration of these systems into 4 industrial demo sites (in Poland, Spain, Greece, and Italy) using digital twin technology, adapting designs to real factory conditions, from biorefineries to paper mills.
Finally, we looked beyond the tech, diving into business models, replication strategies, and the EU policy landscape supporting the shift to cleaner cooling, including new regulations on waste heat recovery and product sustainability.
The RE-WITCH webinar made one thing clear: cooling from waste heat isn’t just possible…. It’s powerful, practical, and already underway!
Did you know? You can now join the next RE-WITCH activities as a player, by integrating our stakeholders’ community?
