What are the differences in environmental toxicity between PVC and polyethylene?

PVC (polyvinyl chloride) and polyethylene are two widely used plastics, but they differ significantly in their environmental toxicity. PVC contains chlorine and often requires additives like phthalates and heavy metals, which can leach into the environment, posing risks to ecosystems and human health. When burned, PVC releases toxic dioxins, a serious environmental hazard.

In contrast, polyethylene is simpler in composition, consisting only of carbon and hydrogen. It does not contain chlorine or require harmful additives, making it less toxic. While polyethylene still contributes to plastic pollution, its environmental impact is generally lower than PVC’s.

For eco-conscious choices, polyethylene is often preferred over PVC due to its lower toxicity and reduced environmental risks. However, both plastics require proper disposal and recycling to minimize harm.
