RE-WITCH project

The RE-WITCH project consists of the recovery and use of waste heat in industry by means of heat and energy production technologies.


RE-WITCH aims to offer competitive and revolutionary solutions in the field of sustainable industrial heat and cold generation. To this effect, the project will demonstrate advanced industrial thermal cooling technologies based on adsorption and absorption processes driven by an optimised combination of low-grade heat (waste heat from the industry itself) and other renewable sources such as solar energy.

To address these challenges RE-WITCH will develop innovative and freely available modelling platforms and engineering solutions to facilitate the design, scale-up, replicability and integration into industrial processes of the proposed technologies.

These solutions will be developed in 4 demonstration sites in Germany, Greece, Spain and Poland, covering the food and beverage sectors, as well as industrial sectors where heat-cooling solutions have not yet been widely explored, such as biorefineries.

IDP is involved in the implementation and application of a BIM-based engineering process, supported by the Digital Twin of each demonstration site. The main objective is to transform unstructured information related to construction projects into structured data. This methodology is expected to reduce execution hours by 15%, while integrating the collection and management of this data in an intelligent way. In addition, it aims to improve sustainability objectives by reducing energy consumption, achieve a Return on Investment (ROI) of over 25%, and reduce manual intervention and duplication of effort by 10% to 30% through more effective collaboration between the various engineering disciplines, from the design stages through to the commissioning and operation phases.

RE-WITCH is funded by the EU under the call: “HORIZON-CL5-2023-D4-01-06”.
