Reuse
Recycle
Which of the following describes Reusing an item?
Breaking down an old car into raw steel
Taking an old tire and turning it into a garden planter
Throwing a broken computer away
Selling an old toy to a second-hand store
Why is Reusing an item usually better for the environment than Recycling it?
Recycling uses less water than reusing
Reusing does not require energy for processing or manufacturing
Recycling creates new materials, which is better for the economy
Reusing only works for plastic, not paper
What is the term for a place where you can drop off and pick up used items for free, promoting the Reuse principle?
Landfill
Reuse Center or Swap Shop
Reconditioning Facility
Recycling Plant

Repair
Reuse
Recycle
Recondition
What is the primary product created from recycled plastic bottles?
New raw oil
Glass sand
New plastic pellets or fibers
Wood chips
Which material is often considered highly valuable to recycle because the recycling process saves over 90% of the energy needed to make a new product from scratch?
Glass
Paper
Cardboard
Aluminum
When you put a plastic bottle in the recycling bin, what is the process called when waste is sorted and processed into materials that can be used again?
Source Reduction
Material Recovery
Waste Disposal
Product Re-engineering
If your bicycle tire has a hole and you fix it with a patch, you are practicing which ‘R’?
Re-engineer
Recondition
Repair
Reduce
What is the main advantage of Repairing a device instead of buying a new one?
It makes the product last forever
It saves resources and prevents electronic waste (e-waste)
It is always free of charge
It requires you to learn a new language
What is the key difference between Repair and Recondition?
Repair is only for furniture; Recondition is only for electronics
Repair is about fixing a small part; Recondition is about a full factory overhaul to a ‘like-new’ state
Repair is done by experts; Recondition is done at home
They are the same thing and mean exactly the same process
