Green manufacturing

  1. 1. Green Manufacturing Presented By: Pradeep Kumar Scholar No.: 13-22-212 Specialization: Design & Manufacturing Department of Mechanical Engineering 2/3/2014 1
  2. 2. Topic Overview  Definitions  Need  Goals  Benefits  Process  Different Aspects  Example in the real world.  Summary 2
  3. 3. What is green manufacturing ?  It is about implementing any kind of substitution in the manufacturing process which leads to a reduction in energy consumption, resource consumption, waste by-products, and water usage.  The design, processing and commercial use of materials processes and products, which are economical and sustainable while minimizing pollution and risk to human health and the environment. 3
  4. 4. Need of green manufacturing  Customers are environment conscious.  Environmental protection is a top agenda for everyone.  Reasons for environmental care  running out of fossil fuel supply (energy crisis) global warming  depletion of the ozone layer  loss of trees and forest  Green manufacturing is a challenge for today but as Business opportunities for tomorrow 4
  5. 5. Green Manufacturing’s Goal  Its goal is to achieve sustainability.  Every company when it comes to green manufacturing should be conserving natural resources for future generations. 5

  9. 9. Process of Green Manufacturing  Lead-Free Soldering for electronics  Reduce Emission of Pollutants  Use of environment-friendly chemicals  Use the lead-free solders to manufacture the products and don’t allow any intentionally added Pb in the products, then the products can be defined as lead-free products.  Packaging Materials – Disposal and Environment-friendly  No release of toxic substances in product life  End of Life Treatment – Recycling of Components, Collection of equipment .  Use of Biodegradable materials . 9
  10. 10. Different Aspects in green manufacturing  JIT Manufacturing  Zero Emission Strategy  ISO 9000 and ISO 14000 10

  15. 15. Example of Green Manufacturing  Murray Ohio Manufacturing Company Wanted to develop ways of reducing scrap metal.  Scrap metal was created because of the depth of the draw on the metal sheets and since the machines created severe deep draws it would tear and mar the metal sheets.  Murray Ohio Manufacturing Used a chlorinated oil with an additive of graphite to create heightened lubricity.  Oil was used as a stamping lubricant  Looked at two different chemicals *Dry Coating Product *Coldkote 15
  16. 16. Products of Murray Ohio Fig no : 7 16
  17. 17.  Dry Coating Product  Required machinery needed 400ft in length.  Teflon coating that the product left made the sheets more slippery.  Cost of machinery was high.  ColdKote  System was 10ft in length.  Non-oil lubricant  Cost of machinery had a payback of six months.  Coldkote the winner  The benefits of Coldkote  scrap metal went from 9% to 1/10 of 1%.  Tool life increased 30-50%.  Polish time went from 3-4days to once a day. 17
  18. 18. Coldkote Green Manufacturing  The removal of Coldkote was used with a warm alkaline bath.  Coldkote becomes a solid compound once its applied therefore reducing the amount of spilling and dripping.  Non-oil lubricant reduces toxicity of company’s waste stream.  A warm alkaline bath eliminates the need for any hazardous cleaning agents.  Decreased spilling and dripping allowed for cleaner facilities. 18
  19. 19. Summary     Green manufacturing is the elimination of waste through the production process Companies must step up and take responsibility for their actions. Green manufacturing promotes innovative design. Processes such as JIT and zero emission should be exercised by all companies. 19
