Ecotoxicological Impact of Bioplastics Biodegradation: A Comprehensive Review

Processes, Год журнала: 2023, Номер 11(12), С. 3445 - 3445

Опубликована: Дек. 17, 2023

The emergence of bioplastics presents a promising solution to the environmental impact plastics industry. Bioplastics are engineered degrade in aquatic or soil environments. However, not all completely biodegradable, and some, like petrochemical-based plastics, may contribute plastic pollution. biodegradability is significantly different conditions such as soil, marine, composting At same time, produced from natural resources contain mixture known unknown materials show 32% cytotoxicity, 42% oxidative stress, 67% baseline toxicity, 23% antiandrogenicity bioassays. extensive biodegradation can also change nutrients, leading eutrophication stunted plant growth. many concerns have arisen, according which be an alternative option for global pollution long run, limited studies focus on this scenario. This review aims provide comprehensive overview by microorganisms their ecotoxicological impacts marine health. In conclusion, while potential sustainable conventional it essential address regarding complete toxicity. Therefore, methods must used production ensure positive environment.

Food wastes for bioproduct production and potential strategies for high feedstock variability

Waste Management, Год журнала: 2024, Номер 184, С. 1 - 9

Опубликована: Май 22, 2024

Unavoidable food wastes could be an important feedstock for industrial biotechnology, while their valorization provide added value the processor. However, despite abundance and low costs, heterogeneous/mixed nature of these produced by processors consumers leads to a high degree variability in carbon nitrogen content, as well specific substrates, waste hydrolysate. This has limited use bioproduct synthesis. These are often instead used anaerobic digestion mixed microbial culture, creating significant knowledge gap higher biochemical production via pure single culture. To directly investigate this gap, various streams processor were enzymatically hydrolyzed characterized, with regard carbon, was quantified. The impact hydrolysate on viability performance polyhydroxyalkanoates biopolymers using bacteria (Cupriavidus necator) archaea (Haloferax mediterranei) sophorolipids biosurfactants yeast (Starmerella bombicola) then elucidated at laboratory-scale. After which, strategies implemented during experimental proof-of-concept study, beyond, improved industrial-scale which addresses discussed in-depth, including media standardization non-selective organisms growth-associated product insights provided would beneficial future endeavors aiming utilize feedstocks biotechnology.

Waste to wealth: Polyhydroxyalkanoates (PHA) production from food waste for a sustainable packaging paradigm

Food Chemistry Molecular Sciences, Год журнала: 2024, Номер 9, С. 100225 - 100225

Опубликована: Окт. 10, 2024

The growing demand for sustainable food packaging and the increasing concerns regarding environmental pollution have driven interest in biodegradable materials. This paper presents an in-depth review of production Polyhydroxyalkanoates (PHA), a polymer, from waste. PHA-based bioplastics, particularly when derived low-cost carbon sources such as volatile fatty acids (VFAs) waste oils, offer promising solution reducing plastic enhancing sustainability. Through optimization microbial fermentation processes, PHA can achieve significant efficiency improvements, with yields reaching up to 87 % content under ideal conditions. highlights technical advancements using packaging, emphasizing its biodegradability, biocompatibility, potential serve alternative petroleum-based plastics. However, challenges high costs, mechanical limitations, need scalability remain barriers industrial adoption. future hinges on overcoming these through further research innovation techniques, material properties, cost reduction strategies, along necessary legislative support promote widespread use.
