VOLKSWAGEN: HEAT RECOVERY FROM TECHNOLOGY

Automotive

An installation of waste heat recovery to municipal District Heating Network (DHN).

 

The challenge

 

Foundry Volkswagen Poznan is the largest foundry of cylinder heads in Europe. Produces annually 4.47 million components, while consuming more than 30 000 tons of aluminum.

The client wanted to increase energy efficiency and reduce its environmental impact.

 

Veolia’s solution

 

An innovation on the scale of Central and Eastern Europe

Veolia Energy Poznań S.A. together with Volkswagen Poznań S.A. has implemented heat recovery from air compressors. The recovered heat is, through a specially designed substation, transferred into District Heating Network of Poznań, owned by Veolia.

Thanks to this solution Veolia can provide “zero-emission” heat to ca. 45 nearby buildings and has reduced carbon dioxide emissions into the atmosphere of 2,440 Mg/year and 3,200 t coal use reduction.

The entire project is the result of over two years of work the engineers of Volkswagen, Atlas Copco and Veolia.

  • Investment in installation of heat recovery to municipal district heating system.
  • Manage the use of waste heat.
  • The sale of the recovered heat in the form of hot water.

 

 

The Benefits

 

  • Reduction of CO2 emissions.
  • Water savings.
  • Reduction of production costs.
  • Raising the guarantee of heat supply.
  • Improved company image - less local emissions.
