The daily use of plastics presents a serious pollution issue due to their extremely slow degradation.Microplastics and the biofilm that grows on plastics(i.e.,the plastisphere)are important subsets of plastic wastes.Many studies have been conducted to reveal the structures of the plastispheres,the ...
“The production of microplastics by the fragmentation of larger plastic items is most effective on beaches, with high UV irradiation and physical abrasion by waves. Once submerged, cooler temperatures and reduced UV means fragmentation becomes extremely slow.” Source: GESAMP, © KIOST. Can we so...
70% of which finds its way to the ocean floor, where it will likely never degrade. (UN, 2006) The Impact The U.S. goes through 100 billion plastic shopping bags annually at an estimated cost to retailers of $4 billion. (The Wall Street Journal) The extremely slow ...
1b corresponds to the most hydrophobic plastics that may not have functional groups for abiotic hydrolysis but most likely have a large percentage of C–H bonds susceptible to photodegradation. In addition to oxidation via photo-initiated processes, extremely slow surface erosion is observed for PE ...
Studying the degradation process, which is known to be extremely slow, using these “tagged” plastics enables us to monitor the production of degradation products such as CO2 with very sensitive detection methods. This allows us to measure plastic degradation in less than a week. In nature, ...
However, there are only very few microbial organisms known to be able to degrade petrochemical-based plastics. Especially PP, PE, PET, PS and PVC usually have an extremely limited biodegradability (see, e.g., (Shah et al., 2008; Urbanek et al., 2018; Danso et al., 2019)). This is...
From the initial development of plastics and particularly since the last half of the 20th century one can say it was extremely spectacular based on its growth rate but more important on how they have helped worldwide. The plastic industry is a worldwide multi-billion dollar business. Exciting ...
This may be due to the reason that lower temperature leads to volatile formation at a slow rate, which allows sufficient time for volatiles to crack into lower hydrocarbons inside the reactor before leaving to the condensation section, whereas at higher temperature, the volatile formation is rapid...
But at the same time, the degradation rates of most plastics in the environment are extremely slow because of their stable chemical structure [10,11]. Therefore, it is conceivable that a great deal of waste plastic is generated every year. A recent report by the Organization for Economic Co...
