Waupaca Foundry team with the Green Sustainability award
Press Release



Oct. 21, 2009—ThyssenKrupp Waupaca’s Plant 1 facility in Waupaca, Wisconsin was recently awarded the Wisconsin Governor’s Award for Excellence in Environmental Performance. This award, now in its 23rd year, was presented to just three companies throughout the entire state and recognizes the achievements of Wisconsin businesses and institutions for their leadership in the area of environmental performance.

Award finalists were selected based on four criteria:

  • Reduction of the degree and amount of waste toxicity;
  • Economic performance as measured by profits generated, costs reduced and payback period; 
  • Transferability of the processes of techniques to similar applications for use by other industries, organizations or institutions; and 
  • Commitment by the applicant to helping other industries, organizations or institutions by sharing information and expertise.


Plant 1 was recognized by Governor Jim Doyle for its use of an innovative closed loop heat recovery system. Heat generated to melt iron used in the plant’s casting operations is moved through an emission control system which destroys the high concentration of carbon monoxide and captures particulate emissions in baghouse filters. Since these filters cannot receive the full load of waste heat and operate effectively, traditional practice has been to discharge the heat into the atmosphere. To receive significant levels of winter heat, ThyssenKrupp Waupaca installed a propylene glycol closed loop heat recovery stem in December 2008. The waste heat warms a water/glycol solution that is moved through coils installed in the facility to provide space heating.


This system provides approximately 70% of the plant heating requirements for a typical winter as well as the hot water needs of the facility. The project, with a cost of $1.8 million, yields approximately $900,000 in savings each year and has led to an annual reduction of 4,600 metric tons of carbon dioxide (the equivalent of gas emissions from 791 passenger cars).
