Teijin reduces greenhouse gas emissions by waste heat recovery

In the thermal processes of the carbon fiber production, a large amount of waste heat is generated and is previously released unused to the environment. Therefore, both companies have decided on a joint project to use the waste heat at the Heinsberg-Oberbruch location. For this purpose, a carbon fiber production plant will be adjusted and approximately 1,500 kW of waste heat will be fed into the Veolia hot water network, which supplies the local industrial companies. In addition, Teijin wants to use the waste heat to heat its own premises. The total yearly savings of 1,500 tonnes of CO2 correspond to the CO2 emissions of around 1,000 diesel vehicles with an annual mileage of 10,000 kilometers each.

For the financial implementation of the waste heat recovery project, the two project partners took part in the “Energy Efficiency” funding competition of the Federal Ministry for Economic Affairs and Energy. This funding program specifically targets the reduction of CO2 emissions in German economy. About half of the eligible costs were approved, the remainder amortized through the use of waste heat at the site due to reduced gas consumption.
