Why are the by-products of a PVC product harmful, unlike PP?

Polyvinyl Chloride (PVC) is the most versatile & economical thermoplastic polymer material widely used across the construction industry for making window & door profiles, water supply pipes, wires, and more. Its unique properties such as light weightiness, durability, and budget-friendliness make it ideal for many projects. But many times, their properties are enhanced by the addition of additives and other chemical compounds.?

However, what makes it fall under the red radar is the fact that PVC poses a threat to the environment and humans. PVC lacks biodegradability and throughout its lifecycle which includes production, use, and disposal, it causes harm to the environment in numerous ways.?

Now, how does PVC pose to be harmful, unlike PP?

Well, PVC is a combination of Hydrogen Chloride and Dioxin. Now, these two by-products of PVC when combusted produce high-level toxins in the form of gases in the environment. Hydrogen Chloride can burn skin and damage the respiratory system as well. Dioxin, on the other hand, is known as a man-made carcinogen that stays in the environment for a really long time. So constant exposure to a carcinogenic substance could lead to acquiring Cancer in the long run - a potential threat to human life.?

Another issue with PVC is that their disposal is tough and complex. They can not be decomposed nor they can be easily burned and if burnt, they release toxic gases into the environment. Even if it is disposed of at landfill sites, it can smolder and release toxins.?

Therefore, despite the strong traits of PVC, it is harmful in multiple ways making it not so ideal. Instead, one can opt for PP which has not only versatile properties but is also super friendly to the environment and humans.?
