Question

which type of waste disposal method produces the most air pollution?

a. composting yard waste

b. incineration of plastics.

c. recycling of paper products.

d. reducing how much you buy to prevent plastic waste.

Explanation:

• Option A: Composting yard waste is a natural process that produces minimal air pollution, mainly some CO₂ and organic compounds, but at a low level.
• Option B: Incineration of plastics involves burning plastic materials, which release harmful pollutants like dioxins, heavy metals, and various toxic gases (e.g., CO, NOₓ, VOCs) into the air, causing significant air pollution.
• Option C: Recycling paper products is an environmentally friendly process that typically has low air pollution associated with it, as it focuses on reprocessing rather than burning or emitting large amounts of pollutants.
• Option D: Reducing plastic waste by buying less is a preventive measure that doesn't involve any waste disposal process, so it has no air pollution from disposal.

Among these, incineration of plastics (Option B) produces the most air pollution due to the toxic emissions from burning plastics.

Answer:

B. Incineration of plastics.
