Analysis should include

describing linear (i.e., cradle-to-grave) and cyclical (i.e., cradle-to-cradle) lifelines of products and materials
defining
- linear lifecycle–considers the product or material from the time of acquisition to disposal.
- cyclical lifecycle–considers the product or material from the time of its acquisition to its being reused, remanufactured, and/or recycled.

Examples of products to analyze may include oil, water, soil, compost, biological waste, cell phones, tennis shoes, tires, product containers, and refrigerators.

Teacher Resources:

Process/Skill Questions:

How does the cradle-to-grave approach handle the end-of-life stage of a product?
How does the cradle-to-cradle approach change the cradle-to-grave approach?
What are the environmental benefits of a cradle-to-cradle product life-cycle?
What is remanufacturing?
How can a given product be redesigned to become reusable?
Why is it important to think about a product's life cycle?
What is more economically efficient for a business, a linear or cyclical approach?
