WebA most prominent and relevant example is high density polyethylene (HDPE) in which the linear hydrocarbon chains pack to crystalline domains by van der Waals interactions. However, crystallinity, even in the presence of cleavable bonds, in general hinders biodegradation of plastics due to inaccessibility for extracellular enzymes to the polymer …
WebLow density polyethylene (LDPE) has a crystallinity of approximately 30–50%, high density polyethylene (HDPE) approximately 80–90%, PP approximately 30–50%, PS approximately 0%, PET approximately 10–30% [25]. However, crystallinity is not a constant characteristic but can be easily altered by physical or thermal treatments [25]. WebPolyethylene terephthalate (PET)-degrading enzymes represent a promising solution to the plastic pollution. However, PET-degrading enzymes, even thermophilic PETase, can …
