Water and soda plastic bottles use Plastic #1 or PET (polyethylene terephthalate). As a raw material, PET is recognized as a flexible material that is 100% recyclable. When the Plastic #1 containers are recycled, they can be made into lots of things: fiber to make clothes and carpeting, sheet and film to make egg and meat containers, strapping, and more bottles.
The circle graph below shows products made from recycled plastic #1.
- Among fiber, sheet & film, strapping, food & beverage bottles, and non-food bottles, which group makes up the largest portion?
- Which group makes up one-fourth of the whole group?
- What group makes up more than non-food bottles but less than sheet & film?
- food & beverage bottles
