The ability of full-scale industrial plants to degrade bioplastics waste must be verified exclude any negative effects on the quality process outputs. This study aims assess degradation two thermoplastic cellulose acetate-based bioplastics, in pure and composite forms both Anaerobic Digestion (AD) Composting (C) conditions. main occurred during AD, where a disintegration about 36% 50% was achieved from acetate, respectively. C did not exceed 20% for samples. combined resulted slightly higher (58–40%) than that obtained revealing how alteration samples an anaerobic environment. Despite this macroscopic degradation, showed only minor superficial as highlighted SEM analysis. FT-IR spectroscopy, TGA andDSC analyses biodegradation mechanism involved mainly plasticizer loss deacetylation matrix, with partial backbone However, were favored AD + processes presence filler These results demonstrated scale can differ significantly those laboratory scale, especially acetate. Furthermore, current optimized treatment bioplastics. Hence, works could help facilities managers emerging materials such more sustainable way.

Sustainable Valorization of Bioplastic Waste: A Review on Effective Recycling Routes for the Most Widely Used Biopolymers

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(9), P. 7696 - 7696

Published: April 22, 2023

Plastics-based materials have a high carbon footprint, and their disposal is considerable problem for the environment. Biodegradable bioplastics represent an alternative on which most countries focused attention to replace of conventional plastics in various sectors, among food packaging significant one. The evaluation optimal end-of-life process bioplastic waste great importance sustainable use. In this review, advantages limits different management routes—biodegradation, mechanical recycling thermal degradation processes—are presented common categories biopolymers market, including starch-based bioplastics, PLA PBAT. analysis outlines that unless blended with other biopolymers, exhibit good biodegradation rates are suitable by composting, while PBAT incompatible require strategies. very promising chemical recycling, enabling building blocks recovery valuable chemicals from waste, according principles circular economy. Nevertheless, only few articles process, highlighting need research fully exploit potentiality route.

Can bioplastics always offer a truly sustainable alternative to fossil‐based plastics?

Microbial Biotechnology, Journal Year: 2024, Volume and Issue: 17(4)

Published: April 1, 2024

Abstract Bioplastics, comprised of bio‐based and/or biodegradable polymers, have the potential to play a crucial role in transition towards sustainable circular economy. The use polymers not only leads reduced greenhouse gas emissions but also might address problem plastic waste persisting environment, especially when removal is challenging. Nevertheless, plastics should be considered as substitutes for proper management practices, given that their biodegradability strongly depends on environmental conditions. Among challenges hindering implementation bioplastics market, development effective downstream recycling routes imperative, increasing production volumes these materials. Here, we discuss about most advisable end‐of‐life scenarios bioplastics. Various strategies, including mechanical, chemical or biological (both enzymatic and microbial) approaches, considered. Employing enzymes biocatalysts emerges more selective environmentally friendly alternative recycling, allowing new added value high‐quality products. Other pending concerns industrial include misinformation among end users, lack standardised bioplastic labelling, unclear life cycle assessment guidelines need higher financial investments. Although further research efforts are essential foster widespread application bioplastics, significant strides already been made this direction.
