Evaluating POSSIBILITIES FOR POLLUTION PREVENTION IN INDIAN INDUSTRIES BY INTRODUCING CLEAN TECHNOLOGIES

Presentation Transcript

  1. ASSESSING POSSIBILITIES FOR POLLUTION PREVENTION IN INDIAN INDUSTRIES BY INTRODUCING CLEAN TECHNOLOGIES Ashok Sharma JSPS ROMPAKU FELLOW GLOBAL ENVIRONMENTAL STUDIES

  2. Environment Vs. Development • Win Lose • Lose Win • Lose Lose • Win Win • Cleantech Offers Solutions CLEANTECH

  3. CLEANER PRODUCTION • Source reduction of pollutants in a facility through changes in Product design, process technology, fuel, materials, practices or innovation • To achieve LOW or NO waste CLEANTECH

  4. PC CP • Begins at the Goes along the end of the pipe process • Coercive Voluntary • Compliant Beyond Compliance • Conventional Innovative • Conservative Creative • Regulatory Promotional • AT COST AT PROFIT CLEANTECH

  5. Cleantech Potential Directly proportional to: • Cost of Materials • Toxicity of Materials • Hazard Potential • Volume of Wastes • Energy intensity of Process CLEANTECH

  6. Emerging CP Technologies • Separation technologies • Handling technologies • Energy efficiency/Clean fuel • Biotechnology/Catalysis • Recycling • Innovation • Tools: LCA, Value Engineering • Landmarks: ISO 14000, Eco-Mark CLEANTECH

  7. CP Equipment PC Equipment • Centrifuge Aerators • Filters Digesters • Membranes Clarifiers • Evaporators Mixers • Compressors Cyclones • Fractionators Filters • Freeze Dryers Scrubbers • Super Critical Reactors ESP’s • Waste heat dryers • Turbocharger • Microwave Dryers • Process simulators • Programmable Controls • Ozonators CLEANTECH

  8. CLEANTECH PROCESS • Preliminary audit • Process analysis & material balance • Hazard/Toxicity potential • Waste streams analysis • CP opportunities & options • CP plans • With capital addition • Without capital addition CLEANTECH

  9. CLEANTECH APPROACHES • No Waste • No Hazard • Waste Exchange • Industrial Complexing – Integrated Production • Design for Environment • Dematerialization • Detoxification • Clean Energy Options • Package of Practices • Innovation management CLEANTECH

  10. Innovative Cleantech modules • Membrane technology • Microwave Drying • Super Critical Extraction • Ozonation/Electrolysis • Hydrogen/Helium power • Waste heat utilization/ Thermo chillers • Thermal Plasma/ E-beam technology • High Rate Fermentation/biotechnology CLEANTECH

  11. Case Studies: Zero Emission • Zero Discharge Electroplating • Zero Discharge Textile Dyeing • Fruit Processing Waste Elimination • The Mushroom Soup Story • Virtual Waterless Manufacturing • No Freshwater Intake • No Wastewater Discharge CLEANTECH

  12. Major interventions Condensate recovery & recycle Ozonztion for mill sanitation/whitening Membrane technology for juice clarification and concentration Significant results Zero freshwater Zero discharge Biocide elimination Sulphur free sugar Energy saving ISO:14000/E-mark Virtual Waterless Manufacturing Cane Sugar Production CLEANTECH

  13. Major interventions Complete recycling of condensate Cold pasteurization by ozonation Detergent free CIP process Elimination of acids Significant results 70% freshwater cut 80% effluent cut Acid/alkali/detergent free processing Zero bacteria Longer shelf life Immunoglobulin Virtual Waterless ManufacturingMilk Processing CLEANTECH

  14. Major Interventions Closing the loop Detergent free wash Non toxic dyes with high transfer rate Microwave drying Super critical CO2 dyeing Significant results Zero Discharge Energy saving 92% Dyestuff utilization No colour No toxicity More money Virtual Waterless Manufacturing Textile Dyeing & Processing CLEANTECH

  15. The Future Implication of CLEANTECH The potential implication of cleantech include: Zero energy approach De-materialization of Production Zero emission A combination of above with resource recycling and co-generation could lead to positive environmental impact

  16. Implication for Indian Industry The self repaying low cost innovation based approach would provide instant opportunity for enviro-management to Indian Industry to beyond compliance levels, simultaneously enhancing their ability to compete globally. This would also unlock the investment potential of Indian Industry for Environment.
