Cleaner Production Based on a presentation by Michael Planasch, Graz University of Technology BUP Teachers Conference Rogow 17-21 May 2011 Graz University of Technology Cleaner Production Institute for Resource Efficient and Sustainable Systems The Concept of Cleaner Production June 30, 2006 Graz University of Technology Cleaner Production The goal is to improve the eco-efficiency in companies by implementation of technical or organisational actions By reducing the negative effects to the environment operating costs are reduced Cleaner Production works with process integrated – preventive - methods instead of End-of-Pipe solutions Institute for Resource Efficient and Sustainable Systems The Concept of Cleaner Production June 30, 2006 Cleaner Production is good not only for the environment but also for the economy! Of course! You make products efficiently, not pollutants - inefficiently Graz University of Technology Total wastewater costs decreased by water saving in a textile company in Austria in 2005 Non Product Water Costs Taking Depreciation, Maintainance and Personal Costs into account: add factor 4-5!!! 100% 90% Cost Percentage [%] 80% 70% others energy chemicals waste water water 60% 50% 40% 30% 20% 10% 0% simple water costs Institute for Resource Efficient and Sustainable Systems non product water costs The Concept of Cleaner Production June 30, 2006 Graz University of Technology Step one in CP is to reduce the amount of resources used, in this case water 1. Start to monitor water use carefully 2. Install valves to close water when not used 3. Fix “low hanging fruits” (leaks etc) 4. Reuse of wastewater (down-classing of water) 5. Recirculation of cooling water after cooling (closed cooling water system) 6. Recirculation of process water (after specific purification) 7. Redesign of processes; specific steps include counter current rinsing etc Institute for Resource Efficient and Sustainable Systems The Concept of Cleaner Production June 30, 2006 Graz University of Technology Step two is to separate wastewater streams Depends on kind of pollutant Separate handling of different waste streams Reduce volume of wastewater Even out peaks by intermittent storing Specific steps include specific chemical steps Institute for Resource Efficient and Sustainable Systems The Concept of Cleaner Production June 30, 2006 Graz University of Technology Examples for CP results 1.400.000 30,0 27,3 Frischwasser - Hl 1.200.000 25,0 prod.
