What is the primary mechanism by which plastic waste releases ozone-depleting substances?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Composting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Incineration, or burning, of plastic waste is a major source of ozone-depleting substances. When plastics are incinerated, they release harmful chemicals, including HFCs, into the atmosphere.
