This work evaluates the preparedness of packaging industry towards more circular, sustainable solutions for fresh meat and fish. The term bioplastic is ill-defined, creating confusion between all stakeholders in value chain. implementation as food contact material will only occur when there are demonstrated that can equally or better protect fish from spoilage, compared to conventional plastic. Price, supply chain availability, machinability, safety also be key shift fossil bioplastic. application at its infancy. In this work, a multidisciplinary approach was employed highlight need holistic eco-design minimizes waste, due high environmental footprint meat.

Biodegradable PLA films incorporating GO‐ZnO hybrid and Mentha Longifolia oil: Fabrication and characterization

Polymer Engineering and Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Abstract The study investigates the effects of graphene oxide/zinc oxide (GO‐ZnO) nanohybrids, combined with Mentha longifolia essential oil, on mechanical, UV resistance, antibacterial, and rheological properties polylactic acid (PLA). GO‐ZnO nanohybrids were prepared at ZnO‐to‐GO ratios 1:1 2:1 incorporated into PLA various concentrations. addition significantly enhanced tensile strength modulus composites due to strong interactions between functionalized nanohybrids. Hydrolytic degradation tests revealed accelerated GO‐ZnO, attributed catalytic ZnO. Rheological analysis showed reduced elasticity higher nanohybrid content, thermal degradation. absorption demonstrated improved protection oil. Antibacterial indicated inhibition percentages against E. coli Listeria , highlighting a synergistic antibacterial effect hybrid system. These findings suggest PLA/GO‐ZnO/oil are promising candidates for packaging applications. Highlights hydrolytic by M. oil catalyze during scission. PBS mechanical via interaction provide in PLA.

Production and characterization of polyhydroxyalkanoates by Halomonas alkaliantarctica utilizing dairy waste as feedstock

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Dec. 15, 2023

Currently, the global demand for polyhydroxyalkanoates (PHAs) is significantly increasing. PHAs are produced by several bacteria that an alternative source of synthetic polymers derived from petrochemical refineries. This study established a simple and more feasible process PHA production Halomonas alkaliantarctica using dairy waste as only carbon source. The data confirmed analyzed halophile could metabolize cheese whey (CW) mother liquor (CWML) into biopolyesters. highest yield was 0.42 g/L in cultivation supplemented with CWML. Furthermore, it proved structure depended on type by-product manufacturing, its concentration, culture time. results revealed H. produce P(3HB-co-3HV) copolymer cultivations CW at 48 h 72 without adding any precursors. Based obtained physicochemical thermal analyses, extracted reported to have properties suitable various applications. Overall, this described promising approach valorizing future strategy industrial management high value microbial biopolymers.
