Which of the following cannot be recycled?

• A. catalytic converters, batteries and transmissions
• B. Motor oil
• C. none of these
• D. Glass

Answer: (C)

Recycling availability depends on having the right facilities to handle each material, but every item listed has a valid recycling path when processed properly. Catalytic converters are collected to recover precious metals; car batteries are routinely recycled to reclaim lead and plastics; transmissions are metal components that go back into scrap metal streams; motor oil is collected and re-refined into new oil; and glass is repeatedly recycled into new glass products. Because each of these materials can be recycled with appropriate programs, nothing on the list must be treated as non-recyclable. So the correct choice is the one that says none of these cannot be recycled.
