  1. Cleaner production • Considers your • Technologies • Employees • Raw materials • Processes • Emissions • Partners and • Products

  2. Elements of a CP-project • Data collection Mass flow Energy flow Costs and safety • Reflection: Where and why do we generate waste? • Option generation • Feasibility • Implementation • Controlling, continuation, EMS

  3. Common waste treatment: Waste is generated! What’sthat got to do with me? Cleaner production: Waste is generated! Where does it come from?

  4. OBSERVED SYSTEM PRODUCTS Primary and secondary MATERIAL EMISSIONS • ENERGY CARRIERS • Fuels, e.g. gas, oil, coal Solid waste, gases, wastewater • ENERGY • Mass free, e.g. electricity or district heating • ENERGETIC • EMISSIONS • Waste heat, noise • MATERIAL • Raw material, process material, other material

  6. Reasons for an environmental team • Becausethere are many different departments/machines in a company, it is difficult to get the necessary overview and the detailed technological knowledge. • Becausethere are motivated and competent employees in a company. • Becauseas a TEAM – with a common goal – it is possible to work more efficiently than a lone ranger. Gather people from differnet departments: production, maintenance, technology, purchasing, management, quality, accounting, research and development, environment, health and safety, legal branch, etc.

  7. Material flow analysis Sankey-diagram: www.sankeyeditor.net

  8. Material flow analysisDetailed description of the material and energy use • Which waste and emission streams are generated? • Which raw materials are lost? • Where and why does this happen? • Where are the weak points? • Where are potentials for improvement? • Which materials can be reused?

  9. Within the production process, there are many points where materials and energy are lost. • These points are also environmental and economic weak points. • A material flowanalysis identifies the points where materials are lost and their amount.

  10. A comparison with the best available technology shows process weaknesses. • The material flow analysis facilitates the evaluation of the "production costs" of waste and emissions. • Eco-efficiency:the best use of materials reduces emissions.

  11. Strategies for cleaner production

  12. Product change • Substitute the product • Increase the product life-time • Change the materials • Change the product design • Use recycled materials • Avoid critical components

  13. Good housekeeping • Improve information • Change dosage/concentration • Increase the utilization of process capacities • Check cleaning and maintenance period • Foster standardization/automation • Improve purchasing, storage and distribution • Carry out a material flow analysis

  14. Waste logistics Separation of waste and wastewater to • Set up closed cycles • Facilitate recovery and re-utilization • Minimize quantities of hazardous waste • Minimize disposal costs • Minimize cleaning expenses (wastewater, exhaust gases, etc.)

  15. Technological modification • Substitute thermo-chemical processes by mechanical alternatives • Use countercurrent cascades instead of single-static rinse techniques • Manage separate waste and wastewater streams • Improve process conditions • Foster recovery and reuse of materials • Increase life time of chemicals/materials • Reduce the infiltration of impurities • Ensure airtight sealing of equipment

  16. Energy efficiencyTypical areas of improvement • Cooling/refrigeration • Heating • Compressed air • Insulation • Heat recovery • Separation processes • Lighting • ...

  17. Internal recycling • Reuse materials (solvents, etc.) • Reuse materials for different purposes (paper, solvents for lower-quality use, e.g. pre-cleaning, etc.) • Close internal loops (water) • Use returnable systems (packaging materials) • Reclaim materials with high value

  18. ECOPROFIT Graz 2000Realized and planned options In total 594 options, thereof: 60 %; 355 = realized options 2000 40 %; 240 = planned options 2001

  19. Anodizing company • Use of spray rinses • Reconstruction of water pipes • Longer drag-out time • Daily check • Reduction in water consumption by 46% (14,000 m³)

  20. Car repair shop • Installation of an ultrafiltration unit • Modified cleaning equipment • Saving of washing agent by 76 %, of water by 80 %
