A Review of Biodegradable Plastics: Chemistry, Applications, Properties, and Future Research Needs

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(16), P. 9915 - 9939

Published: July 20, 2023

Environmental concerns over waste plastics' effect on the environment are leading to creation of biodegradable plastics. Biodegradable plastics may serve as a promising approach manage issue environmental accumulation plastic in ocean and soil. type polymers that can be degraded by microorganisms into small molecules (e.g., H2O, CO2, CH4). However, there misconceptions surrounding For example, term "biodegradable" product labeling misconstrued public imply will degrade under any conditions. Such misleading information leads consumer encouragement excessive consumption certain goods increased littering products labeled "biodegradable". This review not only provides comprehensive overview state-of-the-art but also clarifies definitions various terms associated with plastics, including oxo-degradable enzyme-mediated biodegradation agents. Analytical techniques standard test methods evaluate biodegradability polymeric materials alignment international standards summarized. The summarizes properties industrial applications previously developed then discusses how biomass-derived monomers create new types utilizing their unique chemical from oxygen-containing functional groups. terminology methodologies covered paper provide perspective directions for design possess advanced performance practical benefits.

Degradation of Cellulose Derivatives in Laboratory, Man-Made, and Natural Environments

Biomacromolecules, Journal Year: 2022, Volume and Issue: 23(7), P. 2713 - 2729

Published: June 28, 2022

Biodegradable polymers complement recyclable materials in battling plastic waste because some products are difficult to recycle and will end up the environment either of their application or due wear products. Natural biopolymers, such as cellulose, inherently biodegradable, but chemical modification typically required for obtainment thermoplastic properties, solubility, other desired material properties can hinder even prevent biodegradation process. This Review summarizes current knowledge on degradation common cellulose derivatives different laboratory, natural, man-made environments. Depending environment, be solely a combination several processes, enzymatic hydrolysis, photodegradation, oxidation. It is clear that type especially degree substitution important factors controlling process with environment. The big variation conditions environments also briefly considered well importance proper testing characterization process, confirmation biodegradability. To ensure full sustainability new under development, expected end-of-life scenario, whether recycling "biological" recycling, should included an design parameter.

Biodegradation of Biodegradable Polymers in Mesophilic Aerobic Environments

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(20), P. 12165 - 12165

Published: Oct. 12, 2022

Finding alternatives to diminish plastic pollution has become one of the main challenges modern life. A few have gained potential for a shift toward more circular and sustainable relationship with plastics. Biodegradable polymers derived from bio- fossil-based sources emerged as feasible alternative overcome inconveniences associated use disposal non-biodegradable polymers. The biodegradation process depends on environment’s factors, microorganisms enzymes, polymer properties, resulting in plethora parameters that create complex whereby times rates can vary immensely. This review aims provide background comprehensive, systematic, critical overview this special focus mesophilic range. Activity depolymerization by extracellular biofilm effect dynamic degradation process, CO2 evolution evaluating extent biodegradation, metabolic pathways are discussed. Remarks perspectives future research provided current knowledge gaps if goal is minimize persistence plastics across environments. Innovative approaches such addition specific compounds trigger under particular conditions, biostimulation, bioaugmentation, natural and/or modified enzymes state-of-the-art methods need faster development. Furthermore, must be connected standards techniques fully track process. More transdisciplinary within areas chemistry/processing microbiology/biochemistry needed.
