How does the thermal degradation of polypropylene release harmful byproducts outdoors?
Polypropylene, a widely used plastic, undergoes thermal degradation when exposed to high temperatures outdoors, releasing harmful byproducts. This process occurs due to oxidation, UV radiation, or combustion, breaking down the polymer chains into volatile organic compounds (VOCs), carbon monoxide, and particulate matter. These byproducts contribute to air pollution and pose health risks, including respiratory issues and carcinogenic effects. Incomplete combustion can also produce toxic fumes like formaldehyde and acrolein. Understanding this degradation process highlights the environmental and health hazards of improper plastic disposal and emphasizes the need for sustainable waste management solutions.
