The purpose of this study is to provide a theoretical mechanism during the degradation of polyolefin plastic waste using phytochemicals. Existing degradation (physical, chemical and biological) methods are ineffective, expensive and notably time consuming during the degradation of polyolefin plastics. During the phytochemical degradation process, initially, polyolefin plastic is oxidized and converted into the hydrophilic nature by photo-oxidation. Thereafter, phyto phenols can be used to cleave the main chains of polyolefin plastics, thereby, small molecular hydrocarbons are formed such as oligomers, monomers and dimers. During this process, primary products like all the reactive hydroperoxides and free radicals might be produced and lead to further chain cleavage via peroxide cross linkage. Besides, the consequences of plastic chain cleavage make the product apparently more susceptible to biodegradation. The phytochemical based degradation mechanism is useful for the researchers in the direction towards plastic hazards reduction and management on the earth's environment. |
