Overusing non-degradable plastics causes a series of environmental issues, inferring switch to biodegradable plastics. Polyhydroxyalkanoates (PHAs) are promising that can be produced by many microbes using various substrates from waste feedstock. However, the cost PHAs production is higher compared fossil-based plastics, impeding further industrial and applications. To provide guideline for reducing costs, potential cheap feedstock have been summarized in this work. Besides, increase competitiveness mainstream economy, influencing parameters discussed. The degradation has reviewed related type bacteria, their metabolic pathways/enzymes, conditions. Finally, applications different fields presented discussed induce comprehension on practical potentials PHAs.

Significant progress has been made over the past decade with pilot scale polyhydroxyalkanoate (PHA) production by direct accumulation using municipal waste activated sludge (WAS). However, industrial upscaling experiences are still lacking in research literature. In this study, a demonstration (4 m3) PHA process was operated industrially relevant equipment and compared favourably to those from parallel (200 L) runs. WAS grab samples Dutch full wastewater treatment plant (WWTP) used as biomass source. Final contents yields, that critical for technology viability, were statistically same between experiments conducted at (0.41 ± 0.02 gPHA/gVSS 0.42 gCOD/gCOD) (0.45 0.05 0.39 0.07 gCOD/gCOD). The results furthermore aligned previous 1 m3 piloting five year old historical data similarly sourced WWTP. Scalability robustness of applied methods demonstrated. Temperature foaming control identified be upscaled engineering design towards successful implementations. present combined previously produced PHAs data, support feedstock quality predictably determines both average co-monomer content, well blend distribution. solvent extraction is inherently blending process. Extraction homogeneously mixes polymer contributions collectively stored granules all species microorganisms biomass. Dried PHA-rich batches can stockpiled blended processes recovery formulation reach consistent qualities across batches. More centralized facilities therefore anticipated offer economic benefits due greater opportunities product specification control. Research findings presented herein comparative study along practical perspectives technological readiness realizing based production, control, supply chains will necessary commercial implementation.

The advent of nanotechnology has engineered great interest in synthetic biopolymer-based nanocomposites for use tissue engineering scaffolds, automotives, pharmaceuticals, and so on, due to enhanced mechanical behavior, flexible biodegradation kinetics, biocompatibility. Poly(lactic acid) (PLA), attained from natural materials, exhibit biodegradability, bioabsorbability, with notable demand because inherent versatility applications aforementioned fields. Nevertheless, minimal glass transition temperature, poor thermal dimensional stability, as well ductility, its scope application is restricted. Thus, microfillers nanoparticles such nanoclay, hydroxyapatite, carbon nanoarchitectures, metallic nanoparticles, offering superior mechanical, chemical, thermal, flame retardant properties, are used enhancing PLA behavior. Therefore, this paper presents recently emerging trends bionanocomposites multifunctional applications, including strategies novel fabrication. Further insight on recent advancements biopolymers or saturated poly(hydroxy esters) poly(glycolic (PGA), poly (lactic acid-co-glycolic (PLGA), (caprolactone) (PCL) presented.

Abstract Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption slow degradation, pose threats to ecosystems due its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative petroleum-based plastics, their production costs present significant obstacles global adoption. On the other side, multitude of household industrial activities generate substantial volumes wastewater containing both organic inorganic contaminants. This not only poses threat but also presents opportunities get benefits from circular economy. Main body abstract Production bioplastics may be improved by using nutrients minerals feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia integrated processes have been developed PHA highly polluted with high loads. Various process parameters loading rate, content (volatile fatty acids), dissolved oxygen, operating pH, temperature critical roles accumulation biomass. Research advances are going on downstream recovery utilizing combination physical chemical (halogenated solvents, surfactants, green solvents) methods. review highlights recent developments upcycling resources into PHA, encompassing various strategies, processing methodologies, techno-economic analyses. Short conclusion Organic carbon nitrogen promising, cost-effective source producing bioplastic. Previous attempts focused enhancing productivity through optimizing culture systems growth conditions. However, despite technological progress, challenges persist, such low productivity, intricate processing, scalability issues, properties resulting PHA. Graphical
