Earthling — Using Materials Responsibly Solar Flats

Hi!

I'm Earthling.

Welcome to Solar Flats!

Will you help me investigate using materials responsibly?

The Grumblies have mixed up our clues.

Let's check the evidence!

Reducing use avoids some new material demand.

Reusing keeps an item in service;

recycling processes material into new products.

What does reuse mean?

  • A. Always melting it into raw material
  • B. Throwing away every item
  • C. Using an item again

The answer is C: Using an item again

Reducing use avoids some new material demand.

Reusing keeps an item in service;

recycling processes material into new products.

That clue helps us make sense of this place.

Repair can extend useful life

when an item can still do its job safely.

A design decision should consider the condition, purpose and available resources.

Which action fits the supplied box condition?

  • A. Replace the whole box despite its sound shell
  • B. Repair the divider and reuse
  • C. Discard the whole sound box

The answer is B: Repair the divider and reuse

Our fictional storage box has a loose removable divider,

while its outer shell is sound.

Refit the divider and reuse the box;

the record does not require replacing the whole container.

Hmm...

how does that connect to our first clue?

Our fictional storage box has a loose removable divider,

while its outer shell is sound.

Refit the divider and reuse the box;

the record does not require replacing the whole container.

What distinguishes recycling?

  • A. Processing material into new products
  • B. Simply using the same box again
  • C. Never changing any material

The answer is A: Processing material into new products

Reducing use avoids some new material demand.

Reusing keeps an item in service;

recycling processes material into new products.
