  2. 2. Flow Industrial Ecology What is Industrial Ecology ? Principles of Industrial Ecology? Goals and Benefits of Industrial Ecology Example of Industrial Ecology Life Cycle Assessment Definition and Goals  Process and Case Study Impact Assessment Tools  Uses of LCA Variants of LCA Criticisms LCA benefit for Industry Ecology
  3. 3. Industrial Ecology Industrial Systems Material Energy Economics Sociology Toxicology Systems-based, multidisciplinary discourse that seeks to understand emergent behaviour of complex integrated human/natural systems. Engineering Natural Sciences
  4. 4. Principles Biosphere Society Technological Systems Natural Systems reuse materials and have a largely closed loop cycling of nutrients. Using similar principles, industrial systems can be improved to reduce their impact on the natural environment.

  6. 6. Goals Sustainable development and use of resources at Global, Regional and Local level Preserving Ecological and Human Health Promotion of environmental equity(Inter societal) Minimal use of non renewable resources High degree of inter connectedness and integration that exists in nature

  8. 8. Case Study Seshasayee Paper and Boards Ltd (SPB), in Tamil Nadu. SPB started a paper mill, which went into commercial production in 1962. In order to ensure regular supply of raw material, a sugar mill was set up. The waste from the sugar mill (called bagasse) was used as a raw material for paper- making. Another waste from the sugar mill, molasses, was used in a distillery nearby for the production of ethyl alcohol. In order to ensure regular supply of sugarcane for the sugar mill, the company took interest in the cultivation of sugarcane by organizing the farmers in the region.
  9. 9. Case Study The company strike long-term agreements with the farmers to buy back their produce and, in turn, took the responsibility of supplying them with water. Much of the water supplied for cultivation was the treated wastewater from the paper manufacturing operations The company also used bagasse pith (a waste after the paper making) and other burnable agricultural wastes in the region, as an energy source in their captive power plant .

  21. 21. Life Cycle Assessment Interpretation Systematic technique to identify, quantify, check, and evaluate information Outcome of the interpretation phase is a set of conclusions and recommendations for the study Results from the inventory analysis and impact assessment are summarized during the interpretation phase
  22. 22. USES Research and Development Input to product and process design Design Determination Labeling Education Identify Environmentally friendly products
  23. 23. LCA Variants Cradle to Grave Cradle to Cradle Well to Wheel Gate to Gate Cradle to Gate
  24. 24. LCA Benefit to Industrial Ecology Only tool that examines the environmental impacts of a product or service throughout its life cycle ISO standardized method Comprehensive overview of a product or service Guides Company’s Decision Making
  25. 25. Conclusion Industrial Ecology is the study of how we humans can continue rearranging Earth, but in such a way as to protect our own health, the health of natural ecosystems, and the health of future generations ofplants and animals and humans. It encompasses manufacturing, agriculture, energy production, and transportation
