Sustainability in Engineering Design

ENGR 10

Introduction to Engineering


What does the word sustainability mean to you l.jpg
What does the word SUSTAINABILITYmean to you?

  • Form a small group and discuss this question


Sustainability a definition l.jpg
Sustainability – A Definition

"sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

(Our Common Future, Brundtland Commission of the United Nations, 1987)

?

What are some current issues that are driving engineers (and others) to think about sustainability in design?


What do you think l.jpg
What do you think?

If all people on Earth had the same consumption habits as Americans do, how many Earths would be needed to provide what the world’s population would consume?

  • 1 Earth

  • 2 Earths

  • 6 Earths

  • 20 Earths

When you put your plastics on the curb for recycling, what happens to them?

1. They all get recycled

2. Many of them get thrown away


If you wanted to make a product of plastic which of the following would make it easiest to recycle l.jpg
If you wanted to make a product of plastic, which of the following would make it easiest to recycle?

  • Type 1

  • Type 3

  • Type 5

  • Type 6

  • I don’t know

polyethylene terephthalate

polyvinyl chloride

polypropylene

polystyrene

When you recycle an aluminum can it saves enough energy to power a 60w incandescent light bulb for l.jpg
When you recycle an aluminum can, it saves enough energy to power a 60W incandescent light bulb for:

  • 20 minutes

  • 1 hour

  • 4 hours

  • 12 hours

  • 1 day




Watch film citizens at risk l.jpg
Watch film: Citizens at Risk it?

  • Another film to watch: The Story of Stuff http://www.storyofstuff.com/index.html

  • As you watch think about how this applies to engineering


In your small groups l.jpg
In your small groups it?

  • What is an example of how you might incorporate sustainability in engineering design (particularly in your field of interest)


Sustainability is not a new concept l.jpg
Sustainability is not a new concept it?

  • U.S. National Environmental Policy Act of 1969 → its goal a national policy to

  • "create and maintain conditions under which [humans] and nature can exist in productive harmony, and fulfill the social, economic and other requirements of present and future generations of Americans."



Elements of sustainability l.jpg
Elements of Sustainability it?

  • Economic – example: develop a process to use industrial waste rather than have to pay to get rid of it

  • Social – develop products that don’t disproportionally affect one population

  • Environmental – example: develop processes and products that minimize pollution


How do we judge if a product or service is sustainable l.jpg
How do we judge if a product or service is sustainable? it?

Life Cycle Assessment

(Life Cycle Analysis, Cradle to Grave Analysis)

  • Audit the total impact of the product’s (service’s)

    • resources

    • manufacturing

    • use

    • disposal

  • In terms of

    • energy

    • materials

  • (“Life Cycle Assessment,” n.d.)


    Life cycle assessment lca l.jpg
    Life Cycle Assessment (LCA) it?

    Categories of assessed damages

    • Greenhouse gases (CO2, CH4, N2O, H2O, etc.)

    • Ozone layer depletion

    • Smog

    • Mineral & fossil fuel depletion

    • Habitat destruction

    • Eutrophication (excessive nutrients)

    • Pollutants

    • Desertifcation


    Sustainability examples l.jpg
    Sustainability Examples it?

    • Dell netbooks shipped in bamboo packaging

      • Bamboo - highly renewable material as alternative to molded paper pulp, foams and corrugated cardboard

    • CA Academy of Sciences

      • Green roof – natural insulation

      • Insulation from recycled jeans

      • Photovoltaics

    Bio based bottles l.jpg
    Bio-Based Bottles it?

    • Corn husks

    material use

    • According to Apple:

    • Through ultra-efficient design and use of highly recyclable materials, Apple minimizes material waste at the product’s end of life.

    • Various product take-back and recycling programs in 95% of regions where Apple products are sold.
