The present study reports the role of pretreatment for the enhanced biodegradation of low-d. polyethylene (LDPE) with Galleria mellonella (Greater waxworm). The pretreatment of the LDPE film was carried out under solar radiation. The pretreated LDPE (PTLDPE) and untreated LDPE (UTLDPE) were characterized with AFM, FTIR and 1H NMR techniques. The qual. anal. for the biodegradation of pretreated and untreated LDPE was examined by analyzing the Excreta residue (ER) of Galleria mellonella fed with LDPE. The mineralization of the ER of waxworm fed on Waxcomb (WC), UTLDPE and PTLDPE were studied by analyzing the changes in physiochem. properties through FTIR, 1H NMR and GC-MS techniques in addition to weight loss percentage of PTLDPE and survival rates of the tested greater waxworms. Solar pretreatment of LDPE led to increased surface roughness which favored the waxworms to feed voraciously on PTLDPE. The post degradation studies of Waxcomb (WC), PTLDPE and UTLDPE showed 92.03 ± 2.1%, 18.57 ± 1.8% and 55.8 ± 1.2% weight loss, resp. The FTIR, 1H NMR and GC-MS results confirm that the ER of waxworm fed on WC, UTLDPE and PTLDPE showed the presence of new carbonyl and alc. groups with increase in unsaturated hydrocarbon indicating enhanced mineralization of LDPE. The efficient mineralization of PTLDPE by waxworm was observed without affecting its survivability. A plausible mechanism of LDPE degradation has also been proposed. The rapid and cost effective biodegradation of PTLDPE through waxworm paves a new and facile route for hazardous plastic waste treatment. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Recommanded Product: 84-61-7).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: 84-61-7
