  • Definition as stated by Dr. Foster Green Manufacturing is a philosophy rather than an adopted process because it motivates ongoing improvement efforts even though it may be impossible to achieve.
  • Responsibility does it end at the sale? Does a customer's responsibility end at the landfill when they are finished using the product? Who should decide on the toxic level? The people that live in the neighborhood of the government? In the end no one really knows where anything stops and so therefore companies and individuals must take it upon themselves to help eliminate waste. They should not wait for it to become a law.
  • The reputation of a company to the public is always an important thing because it can float or sink a company. If a company pollutes its neighborhoods, people would begin to move away creating a lack of employees which might damage their production numbers. Eliminating waste saves money because companies wouldn't have to figure out what to do with parts in the end when it could be recycled. Firms that are using green manufacturing create 2x the products due to its research and development. (Richard Florida in California Management Article)
  • Examples of new technologies would be things like pollution prevention, production process modernization, materials substitution. etc. End of life management is the full life cycle starting from the virgin materials to the use and disposal of the final product.
  • Virgin materials can be recycled through the process of distillation and filtering. The distilled or filtered materials could be reintroduced in the life cycle wherever new materials aren't required.
  • As stated in an article by Richard Florida published in California Management: "Corporate companies spent $7.2 billion in pollution abatement and control expenditure of which $3.2 billion were on production process enhancement.
  • Manufacturing systems promotes green design because both strategies are based on the dedication to product improvement, cost reduction, and technology innovation. Improving the manufacturing system simultaneously minimizes cost connected with environmental compliance.
  • Leapfrogging from lily to lily pad means not to jump on every chemical that initially describes itself as more environmentally safe but later on it creates even more problems than the original material. Substituting renewable sources for finite ones might not be completely safe as found in a study between petroleum and plants. The study concluded that even though plants could be used as a substitute the cost in the end might be more and more environmentally dangerous. (Gerngross, Daily University Science News) Companies can fund researches that includes finding substitute chemicals and materials that will eliminate pollution at the top.
  • Little things like recycling paper and soda cans can reduce a lot of waste cost. Companies that produces materials can decide whether or not they want to contract another company to make certain parts because those companies might have better equipment and higher vertical control technology.
  • Collaboration between companies and their suppliers creates opportunities for new design products and processes that are more efficient and environmentally friendly. Continuous improvement creates an incentive for waste reduction and cost saving.
  • Study done on National US Manufacturing firms found that most companies were moving from ISO 9000 to ISO 14000 such as Sony Corp and Safety Kleen.
  • 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.
  • A warm alkaline bath eliminates the need for any hazardous cleaning agents. Decreased spilling and dripping allowed for cleaner facilities.

    18. 18. Example of Green Manufacturing <ul><li>Murray Ohio Manufacturing Company </li></ul><ul><ul><li>produces lawn mowers and bicycles </li></ul></ul><ul><li>Wanted to develop ways of reducing scrap metal. </li></ul>
    19. 19. Murray Ohio Manufacturing <ul><li>Used a chlorinated oil with an additive of graphite to create heightened lubricity. </li></ul><ul><ul><li>Oil was used as a stamping lubricant </li></ul></ul><ul><li>Looked at two different chemicals </li></ul><ul><ul><li>Dry Coating Product </li></ul></ul><ul><ul><li>Coldkote </li></ul></ul>
    20. 20. Murray Ohio Manufacturing <ul><li>Dry Coating Product </li></ul><ul><ul><li>Required machinery needed 400ft in length. </li></ul></ul><ul><ul><li>Teflon coating that the product left made the sheets more slippery. </li></ul></ul><ul><ul><li>Cost of machinery was high. </li></ul></ul><ul><li>ColdKote </li></ul><ul><ul><li>System was 10ft in length. </li></ul></ul><ul><ul><li>Non-oil lubricant </li></ul></ul><ul><ul><li>Cost of machinery had a payback of six months. </li></ul></ul>
    21. 21. Coldkote the winner <ul><li>The benefits of Coldkote </li></ul><ul><ul><li>scrap metal went from 9% to 1/10 of 1%. </li></ul></ul><ul><ul><li>Tool life increased 30-50%. </li></ul></ul><ul><ul><li>Polish time went from 3-4days to once a day. </li></ul></ul>
    22. 22. Green Manufacturing <ul><li>Coldkote Green Manufacturing </li></ul><ul><ul><li>The removal of Coldkote was used with a warm alkaline bath. </li></ul></ul><ul><ul><li>Coldkote becomes a solid compound once its applied therefore reducing the amount of spilling and dripping. </li></ul></ul><ul><ul><li>Non-oil lubricant reduces toxicity of company’s waste stream. </li></ul></ul>
    23. 23. Are you an expert on Green Manufacturing? <ul><li>What is one of the benefit for green manufacturing? </li></ul><ul><li>Green manufacturing includes employees. True or False. Explain. </li></ul><ul><li>Why should your company even think about green manufacturing? </li></ul>
    24. 24. Answers for the non-experts. <ul><li>One of the benefits of green manufacturing would be reducing cost because in the end the company may not have to shell out money to remove the waste when waste has already been eliminated on the first step. ( Zero Emission Strategy ) </li></ul>
    25. 25. Answers for the non-experts. <ul><li>Employees are included in every step of the green manufacturing process. In order to have better quality which is linked to better manufacturing services, employees must be involved from the designing of the process to just recycling office materials. </li></ul>
    26. 26. Answers for the non-expert <ul><li>A company should consider green manufacturing because it makes their standards a little higher in quality than others. Saving cost and increasing production could also be an incentive for a company to even think about green manufacturing. </li></ul>
    27. 27. Summary <ul><li>Green manufacturing is the elimination of waste through the production process. </li></ul><ul><li>Companies must step up and take responsibility for their actions. </li></ul><ul><li>End-of-life management used more often then end-of-pipe control. </li></ul>
    28. 28. Summary <ul><li>Green manufacturing promotes innovative design. </li></ul><ul><li>Processes such as JIT and zero emission should be exercised by all companies. </li></ul><ul><li>Green manufacturing saves cost but more importantly it saves valuable resources. </li></ul>
