Geuskens (London: Wiley), 2341. Different levels of degradability are thought to depend on the extent of amorphous and crystalline forms, and the presence of strong CC bonds, which are very resistant to attack by enzymes. Although no plastic is entirely protected against UV rays and radiation, many plastics offer excellent levels of UV resistance that increase lifespan, prevent elongation, and fight the effects of photodegradation such as chalking, loss of

The degradation of polyurethane topcoat over a chromate pigmented epoxy primer was examined by atomic force microscopy (AFM), scanning electronic microscopy (SEM), X-ray photo-electron spectroscopy (XPS) and Fourier transform infra-red spectroscopy (FTIR) after the coated panels were exposed in a QUV chamber.

For many outdoor applications, the simple addition of carbon black doi: 10.1128/AEM.42.1.180-183.1981, Cassone, B. J., Grove, H. C., Elebute, O., Villanueva, S. M. P., and LeMoine, C. M. R. (2020). A., Hameed, A., and Ahmed, S. (2007). 84, 480482. Polyhydroxyalkanoates (PHAs) have emerged as a sustainable choice due to their putative high biodegradability in different environments, biocompatibility, chemical diversity, their manufacture from renewable carbon resources, and release of non-polluting and non-toxic products after degradation (Bhatia et al., 2019a, b). Rev. Polyethylene, polypropylene, polystyrene, and polyvinyl chloride have a backbone which is solely made of carbon atoms. Thus, mechanisms of petro-plastic degradation can be classified into three groups: (i) Polymers with carbon back-bones; (ii) Polymers with ester-bond back-bones and side-chains; and (iii) Polymers with hetero/carbamate(urethane) bonds. Crit. doi: 10.1073/pnas.1718804115, Auta, H. S., Emenike, C. U., and Fauziah, S. H. (2017). Appl. Lett. The fusion of polyamidase and PBM (PA-PBM) improved hydrolysis of PU polymers by fourfold relative to the native enzyme (Gamerith et al., 2016). (2004). J. Appl.

A novel FTIR-ATR spectroscopy based technique for the estimation of low-density polyethylene biodegradation. PET consists of aromatic polyesters with high glass transition temperatures (Tg) of approximately 7580C in air. doi: 10.1016/S0922-338X(97)82013-2, Nechwatal, A., Blokesch, A., Nicolai, M., Krieg, M., Kolbe, A., Wolf, M., et al. The stability of polyurethane elastomers based on different building blocks of macrodiols (polyester, polyether, polycarbonate, polybutadiene, and polyisobutylene), isocyanates (aromatic and aliphatic), and chain extenders (diols, triols, and diamines) are summarised, and the mechanisms of different types of degradation are presented. Agents known in industry as UV stabilizers, blockers, and absorbers can mitigate the damaging effects of UV exposure. Degradation and Recyclability of poly (ethylene terephthalate), in Polyester, ed. Stored Prod. 33, 103113. Cutinases (EC 3.1.1.74) are a sub-class of esterase enzymes that have gained importance because of their ability to hydrolyze polyesters with a high molar mass (Chen et al., 2013).
13, 1931. Appl. Bull. The biodegradation pathways utilized by these two groups are significantly different (Wei and Zimmermann, 2017). 63, 335342. (2018) used Markov Model-based search strategy to show that a surprisingly large variety of potential polyesterases still needs to be discovered particularly in bacteria, which are currently not considered as a prime source for cutinases (Danso et al., 2018). doi: 10.1111/1462-2920.14703, Liebminger, S., Eberl, A., Sousa, F., Heumann, S., Fischer-Colbrie, G., Cavaco-Paulo, A., et al.

(2018). The polyurethane (PU) was synthesized by prepolymerization method with isocyanate/polyol group ( [NCO/OH]) in ambient temperature and exposed the obtained solid film to gamma irradiation at various doses from 0 up to 150 kGy. Appl. Technol. Hazard Mater. (2017). 15, 177192. The first step involves hydroxylation of C-C bonds to release primary or secondary alcohols, which are oxidized to ketones or aldehydes, and subsequently to hydrophilic carboxylic acids (Alvarez, 2003; Watanabe et al., 2003). The genetic mechanism for the pathways enabling EG metabolism has been well demonstrated in P. putida. Appl. A variety of bacterial strains were able to use polyester-polyurethane polymers as carbon, nitrogen and energy source for growth, e.g., P. aeruginosa (Kay et al., 1991), Corynebacterium sp. doi: 10.1016/j.procbio.2017.01.004, Geyer, R., Jambeck, J.
