Polyester was one of the most popular fibers used in fashion in 2017, found in about 60% of garments in retail stores and equalling about 21.3 million tons of polyester fiber. [32] There was a 157% increase of polyester clothing consumption from 2000 to 2015. [32]
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Degradation arising from the effects of heat, light, air and water is the most common, but other means of degradation exist. The in-service degradation of mechanical properties is an important aspect which limits the applications of these materials. Polymer degradation caused by in-service degradation can cause life threatening accidents.
In polymers, such as plastics, thermal degradation refers to a type of polymer degradation where damaging chemical changes take place at elevated temperatures, without the simultaneous involvement of other compounds such as oxygen.

According to co-author Patricia Villarubia-Gómez from the Stockholm Resilience Centre, "There has been a 50-fold increase in the production of chemicals since 1950. This is projected to triple again by 2050". There are at least 350,000 artificial chemicals in the world. They have mostly "negative effects on planetary health". Plastic alone ...
The new jerseys are part of Nike's Vapor Premier template, which MLB is using for the first time. The material is described as “breathable, lightweight, high-performance fabric that was made ...
The long-term effects of plastics in the food chain are poorly understood. In 2009 it was estimated that 10% of modern waste was plastic, [ 58 ] although estimates vary according to region. [ 57 ] Meanwhile, 50% to 80% of debris in marine areas is plastic. [ 57 ]
