Although polypropylene clothes are not easily flammable, they can melt, which may result in severe burns if the wearer is involved in an explosion or fire of any kind. [52] Polypropylene undergarments are known for retaining body odors which are then difficult to remove. The current generation of polyester does not have this disadvantage. [53]
A plastic is considered a bioplastic if it was produced partly or wholly with biologically sourced polymers. A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44]
Furthermore, only about 9-10% of discarded plastics are recycled each year. Non-biodegradable plastics accumulate in the environment, threatening human, animal, and environmental health. Current solutions to dealing with the amount of plastic being thrown away include burning the plastics and dumping them into large fields or landfills.
A goal is not to elicit the immune response, and the products of degradation also need not to be toxic. These are important as biodegradable polymers are used for drug delivery where it is critical to slowly release the drug into the body over time instead of all at once and that the pill is stable in the bottle until ready to be taken.

Biodegradable bags still strong enough to carry shopping after three years in the ground show that 'biodegradability' isn't all it's cracked up to be. When biodegradable plastic is not ...
Susceptibility to biodegradation is highly dependent on the chemical backbone structure of the polymer, and different bioplastics have different structures, thus it cannot be assumed that bioplastic in the environment will readily disintegrate. Conversely, biodegradable plastics can also be synthesized from fossil fuels. [4] [12]
Although the synthetic substance is not fully biodegradable and doesn't simply disappear in its entirety, a large percentage of the makeup of PVA is biodegradable and the substance is considered ...
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
