2. What Is Green Manufacturing?
• Green manufacturing is a method for
manufacturing that minimizes waste and
pollution. These goals are often achieved
through product and process design.

3. Terms to Know
• Here are some terms to help you better
understand the idea of green
manufacturing:
• Product design – includes the the definition
of the product architecture and the design,
production, and and testing of a system for
production.

4. Terms to Know (2 of 2)
• Three life cycle approaches to product design:
• Design for reuse – refers to designing products so that
they can be used in later generations of products.
• Design for disassembly – a method for developing
products so that they can be easily taken apart.
• Design for remanufacture – a method for developing
products so that the parts can be used in other products.

5. Goal of Green
Manufacturing
• The purpose is to support future
generations by attaining sustainability by
the means of preserving natural resources.

6. Nuts & Bolts
• “Environmentally benign manufacturing will
become one of industry’s greatest
strategic challenges, not only from an
engineering perspective, but from a
business and marketing perspective as
well.” (3)

7. Strategic Challenges
• Range of coordinated actions
• Trade and environment policies (mutually
supportive)
• Eliminating environmental harmful subsidies
• Promoting the transfer of technologies and financial
resources
• Efficient operation of markets
• Achieving greater international cooperation (4)

8. Obstacles
• Businesses have a responsibility of
influence
• Prices of raw material and subsidized
energy are essential
• Lack of availability and information (4)

9. Obstacles (2 of 2)
• High-profile leadership
• Training programs need more support
• Accessibility to loans from the government
• National cleaner production centers need
to be established (4)

10. How It Works
1) Rethink product and process technology
2) Explore the market potential
3) Supply goods and services
4) Extend producer responsibility (4)

11. How It Works (2 of 2)
1) Reduce energy consumption
2) Integrate promotion
3) Incorporate goals
4) Promote development
5) Integrate environmental costs (4)

12. Real World Example
• The need for fossil fuels has lead to
discoveries of different methods of
manufacturing that replace renewable
resources.

13. Real World Example
• Petroleum.
• Fossil fuel base for plastic.
• Can be replaced by plants.
» Corn can be fermented into
polyhydroxyalkanoates (PHA).
» Final product is synthesized biologically and
completely biodegradable.
• Fast food and packaging industry use polystyrene which
has similar characteristics as PHA.

14. Real World Example – How It
Works
• Corn is grown and harvested
• Transported to manufacturing plant
• Glucose extracted and fermented
• Cells are washed and spun in centrifuge twice
• Concentrated and dried into powder

15. Critical Thinking Exercise
• “Do you think that this process of turning
corn or plants into other fossil fuels will be
beneficial to the environment in the
future?” (3)
• Why or why not?

16. Researched Response
• More energy is consumed during polymer
production through plant fermentation.
• Energy is required to produce fertilizer, insecticide,
and herbicides.
• Energy is also required in growing, harvesting, and
processing. (3)

17. Researched Response (2 of 3)
• Total energy for 1 lb. Of PHA s equal to the
utilization of 2.38 lbs of fossil fuel resources
• Same amount of polystyrene using chemical
manufacturing needs only 2.26 lbs of oil
• 19 times more electricity, 22% more steam, and
seven times more water (3)

18. Researched Response (3 of 3)
• 2.39 lbs would have to be burned to make energy
in fermentation
• 1.26 lbs would be burned in chemical
manufacturing
• Polluting effects are greater (3)

19. Predictions
• “Given adequate support, renewable energy
technologies can meet much of the growing demand at
prices lower than those usually forecast for
conventional energy. By the middle of the 21st century,
renewable resources of energy could account for 3/5 of
the world’s electricity market and 2/5 of the market for
fuels used directly. Moreover, making a transition to
renewable-intensive energy economy would provide
environmental and other benefits not measure id
standard economic accounts”.(4)

20. Summary
• “Cleaner production is a preventive strategy that
aims at promoting the use and the development of
cleaner, processes, products, and services”. (4)
• “A key to more sustainable development is long-
term structural changes in the way our economies
work”. (2)
