  • ZERMEG Zero Emission Retrofitting Method in Z E i i R t fitti M th d i Galvanizing industry Dr. Johannes Fresner gefördert aus Mitteln der Fabrik der Zukunft (www.fabrikderzukunft.at)
  • STENUM GmbH  Environmental consulting and research company – National and international  Field of Work: – Consulting, research and training in the field of cleaner production, process optimisation and sustainable development – Eco-efficiency: energy, material, waste and water management – Environmental management systems according to ISO 14001 and EMAS g ZERMEG
  • The approach of ZERMEG I Calculation of ideal minimum consumption •Numerical model of ideal minimum consumption. p •Gap analysis. •Identification of options. ZERMEG
  • Pickling plants: Initial situation Identified losses:  High drag out  No defined rinsing criterium  Insufficient control  Over flow  Early dumping  Not exact dosage of chemicals g  Bad mixing  Bad removal of oil, grease and solids g  Violation of procedures  Inadequate rinsing technology or procedure ZERMEG
  • Results - overview ZERMEG
  • Example: A Heuberger A.Heuberger Specific water consumption at Anodisieranstalt Heuberger 1,2 1 0,8 0,6 0,4 0,2 02 0 1996 1997 1998 1999 2000 2001 2002 2003 ZERMEG
  • Example: A Heuberger A.Heuberger  Specific water consumption was reduced by 95%  Specific consumption of natural gas was reduced by 50%  Specific consumption of chemicals was reduced by 20%  P d ti i Production increase t 300% to  Rate of mistakes reduced to <<1% ZERMEG
  • ZERMEG II  TRIZ based  Uses function modelling (related to natural language)  Uses Ideal Final Result and backcasting  Uses „Trimming“ questions „Trimming ZERMEG
  • Flow chart plus IFR: brainstorming function modell CURRENT IDEAL SITUATION S O FINAL RESULT Current Intermediate Function achieved Design … solutions without cost or harm Set of questions: brainstorming Source: Support manual, Jantschgi, Mann, Grawatsch 2003 ZERMEG
  • Simple function model of pickling and rinsing f i kli d i i crane c ane holds rack ack holds part pa t holds holds controls film oxide dissolves dilutes deactivates operator water opens bath releases valve generates Waste water Spend bath ZERMEG
  • Trimming questions g  Can components or functions be eliminated?  Can the need for a function be eliminated?  Can functions of other components or the components themselves be taken over?  Can unwanted functions be eliminated by y other functions?  Can components be replaced by other components?  Can components be replaced by existing resources?  Can the system take over functions itself?  Can freely available resources be used? y ZERMEG
  • Results:  Omax Orient, Union Steel, Omax, Orient Steel Austria Buntmetall : -30% water 30%  Austria Email: -50% water, sulfuric acid: -75% lf i id 75%  SKM Leiterplatten: -30% water  Adapted to the textile p industry ZERMEG
  • Awards National Award for environmental and energy technology 2008 in the category: „Environmental technology and Environmental environmental services“ STENUM was nominated as a finalist for the awards: – ÖGUT Umweltpreis 2007 – Austrian Constantinus, Category „Management Consulting“ – Fast Forward Award Styria – Energy Globe ZERMEG
