A dynamic duo

  • Installing a CHP unit offers a multipurpose, efficient energy solution
  • € 19 100 savings on energy costs and 79 tonnes of CO2 emissions are anticipated

The German company AKRO-PLASTIC GmbH produces plastic compounds, which are processed into technical components for the automotive industry by other companies. The company mainly uses a twin-screw polymer extruder, but also strand and underwater pelletising.

At one location, the production and administration buildings are heated by a 300 kW gas boiler. The boiler preheats air in the ventilation system and warm water for the administration building.

The company has plans to install an energy-efficient combined heat and power plant (CHP) at the cost of € 113 000.

Key benefits

Heat from the CHP is to be used for building heating and warm-water processing. The gas boiler remains in place to cover peak loads. Thanks to a more efficient heating system, the company stands to save € 19 100 on energy costs per year and reduce CO2 emissions by about 79 tonnes annually.
