asynthetic fibres are mostly plastics, made from petroleum chemicals. Examples include nylon, polyester and acrylic fibres. synthetic fibres have some advantages over natural fibres. They are usually much stronger, resist insect attack and do not rot absorb water, which means that they dry quickly....
Plastics are man-made materials — many of them derived from oil or other petroleum products. They can break down into smaller particles, through exposure to heat and weather and even animal digestion. Researchers have increasingly been interested in microplastics, which can be as wide as a pen...
Researchers are still trying to understand exposure levels, but study after study is finding signs of plastics in body tissues. "Microplastics have been measured in pretty much all of the body tissues that have been evaluated," said Tracey Woodruff, PhD, MPH, a University of California San Fran...

Abstract The constant rise in global demand for plastic products has led to an uninterrupted increase in the production and utilization of petroleum-based conventional plastics. This has resulted in significant contamination of plastic waste due to its non-biodegradable nature, particularly within aquatic...
chain bonds are broken. Regarding petroleum-based polymers (PET, PE, etc.), they are generally more resistant due to the presence of aromatic hydrocarbons [42]. Similarly, other non-vinyl polymers such as polyurethanes, polyamides, and polystyrenes, and cellulose derivatives such as acetates, ...

The uncontrolled expansion in the utilization and irresponsible abandonment of synthetic plastics has engendered a pressing concern over environmental well-being, because of the harmful effects of petroleum-based synthetic polymeric compounds. The impact of plastic materials, particularly their accumulation in...
apparel & textile, consumer electronics, environmental services, etc. Around 50% of all bio-based plastics produced are drop-in plastics — bio-based, non-biodegradable materials obtained from renewable sources with identical technical properties as their petroleum counterparts, such as bioderived-PE ...
