Cleaner Production Based on a presentation by Michael Planasch, Graz University of Technology BUP Teachers Conference Rogow 17-21 May 2011
2
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Cleaner Production
3
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 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
4
Cleaner Production is good not only for the environment but also for the economy! Of course! You make products efficiently, not pollutants - inefficiently
5
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Total wastewater costs decreased by water saving in a textile company in Austria in 2005 Taking Depreciation, Maintainance and Personal Costs into account: add factor 4-5!!!
6
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 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
7
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 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
8
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Examples for CP results
9
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Pulp and paper Pulp and paper industry changed bleaching chemistry and decreased pollution dramatically

Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006
11
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 5 Basic Principles of CP Input-Substitution Good Housekeeping Internal Recycling Technological Optimisation/Change Optimisation of the Product
12
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Input-Substitution Use of less hazardous raw-, auxiliary- or operating materials Use of operating materials with a longer life-time
13
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Good Housekeeping Increasing the Material and Energy efficiency with actions in the process. Try to fetch the „Low hanging fruits“ first Reducing losses due to leakage Training of employees …
14
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Internal Recycling Closing of Material and Energy Loops (Water, Solvents,…) Cascading of Material and Energy streams
15
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Technological Optimisation/Change Implementation of new technologies Improved process control Redesign of processes Change in or Substitution of hazardous processes
16
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Optimisation of the Product Increasing the life-time Easier reparing Easier demanufacturing, recycling or deposition Use of non-hazardous materials
17
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Environmental protection reduced air and water pollution 1985 2000 2015 1985 2000 2015 end-of-pipe – treatment recycling reuse incineration save disposal
18
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 Eco-efficiency, IPPC, CP 1985 2000 2015 1985 2000 2015 good housekeeping waste minimization closing cycles energy efficiency Cleaner Production
19
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 The shift from continuous improvements to redesign 1985 2000 2015 1985 2000 2015
20
Institute for Resource Efficient and Sustainable Systems Graz University of Technology The Concept of Cleaner Production June 30, 2006 The paradigm shift in environmental protection Fighting symptoms Sub-system optimization Meta-system optimization System optimization 1985 2000 2015 1985 2000 2015
