Volkswagen and Veolia in industrial heat recovery project for local community

Veolia Energy Poznań with Volkswagen Poznań have launched a joint project for industrial heat recovery. Energy, heat from industrial processes, is used to supply more than 30 buildings in the district Wilda, including the HCP hospital in Poznań.
Thanks to our oil free screw compressors, which are necessary in the foundry of Volkswagen Poznań, this very energy-intensive process (up to 80% of the electricity consumed by the compressor goes into heat energy) is transformed to power the municipal heating system.
