B13 Product Life Cycle
 If each container could talk about its life, what would it
say?
 Materials Engineers use the term “life” to describe the
stages a product goes through from its origins as raw
materials until it’s been disposed of.

Key Points and Vocabulary
Lab Check for B13
 1. For the drink container you were assigned:
 a.What are its raw materials?
 b. Does the product have more than one end-of-life
option? Explain.
 Plastic
 Raw Materials: petroleum, natural gas
 End-of-life options: landfill, recycle some
 Aluminum
 Raw materials: bauxite, sodium phosphate solution
 End-of-life options: recycle, landfill
 2. Use your life-cycle diagram to explain what would
happen to all of the other stages in the life cycle of the
drink container if:
 a. the demand for the drink container increases.
 Need for more raw materials, more energy needed to
gather raw materials
 More energy needed to manufacture the material and
the containers
 More waste produced during manufacturing
 More used containers sitting in landfills
 b. the raw materials used to make the product run out.
 No materials to make the product
 No waste produced from manufacturing
 Companies need to find other materials to make the
containers
 Need to rely on recycled materials only
 No more containers added to the landfills
 c. materials engineers design a way to manufacture the
container with less waste produced.
 Less raw materials needed from the earth
 Less waste produced
 3. Explain why or why not a life-cycle diagram would be
a useful tool for:
 a. the director of a drink company who wants to choose a
container for a new drink.
 b. a materials scientist working to reduce the negative
impact a drink container has on the environment.
 c. a person buying a bottle of sports drink in a store.
 in each case the life-cycle diagram would help the
person to see the steps that go into the entire life of
the product. Which in turn helps when making an
informed decision.
 4. Look at the life cycle of a product shown on Student Sheet
13.1,“Stages in the Life Cycle of a Product.” Using the “Green
Chemistry Guidelines” on Student Sheet 13.2, make a list of
ways to reduce the negative environmental impact of this
product.
 Reducing the amount of raw materials needed at each

stage.
Reducing the amount of materials needed as inputs in the
manufacturing stage.
Reducing the amount of waste produced at each stage.
Increasing the amount of materials that are recycled to
decrease the volume of raw materials needed at the
manufacturing stage.
Accept any suggestion that would reduce energy and
resources as inputs and reduce the amounts of waste as
outputs.
B13 Product Life Cycle
 Key Points
 A material has characteristic properties.
 Technological solutions have intended benefits and
unintended consequences. Some consequences can
be predicted, and others cannot.
 Diagrams and models can demonstrate scientific
concepts.
B13 Product Life Cycle
 Vocabulary
 life cycle - The progression through a number of steps or
different stages in the manufacture, use, and disposal of a
product. For example, obtaining and refining a copper ore,
making a penny, using a penny, and the eventual corroding of
the penny. In animals and plants, life cycle refers to the
developmental stages they pass through from birth to death.
 Raw materials - The first stage of four stages in a product’s
life cycle. Raw materials need to be extracted from the earth
in order to manufacture a product.
 Manufacturing - The second stage of four stages in a
product’s life cycle. It is when the product is created from
raw materials.
 Useful life - The third stage of four stages in a product’s life
cycle. This is the time that a manufactured product may be
used productively.
 End of life - The fourth and final stage in a product’s life
cycle, when a product is no longer useful.
