“…Chitosan has been widely studied in different fields, such as alcoholic fermentation, due to its role in metal chelation, and the clarification and reduction of contaminants in enology [ 29 ], in the food industry [ 30 ], or for microbial control [ 31 ]. Moreover, chitosan is one of the most important derivatives of chitin, and is obtained through the partial deacetylation of chitin [ 32 ]. Both chitin and chitosan are polymers that are biodegradable, biocompatible and non-toxic [ 33 ].…”

In this work, different poly (lactic acid) (PLA)-based nanocomposite electrospun fibers, reinforced with both organic and inorganic nanoparticles, were obtained. As organic fibers, cellulose nanocrystals, CNC, both neat and functionalized by “grafting from” reaction, chitosan and graphene were used; meanwhile, hydroxyapatite and silver nanoparticles were used as inorganic fibers. All of the nanoparticles were added at 1 wt% with respect to the PLA matrix in order to be able to compare their effect. The main aim of this work was to study the morphological, thermal and mechanical properties of the different systems, looking for differences between the effects of the addition of organic or inorganic nanoparticles. No differences were found in either the glass transition temperature or the melting temperature between the different electrospun systems. However, systems reinforced with both neat and functionalized CNC exhibited an enhanced degree of crystallinity of the electrospun fibers, by up to 12.3%. From a mechanical point of view, both organic and inorganic nanoparticles exhibited a decreased elastic modulus and tensile strength in comparison to neat electrospun PLA fibers, improving their elongation at break. Furthermore, all of the organic and inorganic reinforced systems disintegrated under composting conditions after 35 days.

This research work is aimed to convert fish scale wastes as an effective reinforcement in polylactic acid (PLA) as a new bio-composite filament for fused deposition-based 3D printing applications. Various concentrations of fish scale particles (0, 10, 20, and 30%) were used to make the filaments. The performance of the developed filaments was assessed by printing the filament into various test specimens to perform tensile, flexural, impact, hardness, and water absorption experiments as per the ASTM standards. The outcomes of the results show that the PLA/fish scale powder (20%) composite has performed well than the remaining composites. Furthermore, the adding 20% fish scale powder increased the tensile strength and flexural strength of the 3D printed PLA composite by 15% and 39.78% respectively. This is evident that the novel bio-composite exhibited better properties than the pure polymer making it a potential replacement as bone-grafting material and scaffolds for bio-engineering applications.

“…The generation of these marine by-products without the concurrent development of adequate recovery processes leads to environmental deterioration and serious pollution concerns. Seafood-based companies use roughly 25–30% of the total biomass for human consumption, while the other fractions are discarded as waste, with the shell making up the lion's share [ 2 ]. As a result, the aquaculture and seafood-processing sectors generate a significant amount of waste on a worldwide scale every year.…”

Background There are substantial environmental and health risks associated with the seafood industry's waste of crab shells. In light of these facts, shellfish waste management is critical for environmental protection against hazardous waste produced from the processing industries. Undoubtedly, improved green production strategies, which are based on the notion of "Green Chemistry," are receiving a lot of attention. Therefore, this investigation shed light on green remediation of the potential hazardous crab shell waste for eco-friendly production of bacterial alkaline phosphatase (ALP) through bioprocessing development strategies. Results It was discovered that by utilizing sequential statistical experimental designs, commencing with Plackett–Burman design and ending with spherical central composite design, and then followed by pH-uncontrolled cultivation conditions in a 7 L bench-top bioreactor, an innovative medium formulation could be developed that boosted ALP production from Bacillus licheniformis strain ALP3 to 212 U L−1. The highest yield of ALP was obtained after 22 h of incubation time with yield coefficient Yp/s of 795 U g−1, which was 4.35-fold higher than those obtained in the shake-flask system. ALP activity has a substantial impact on the volatilization of crab shell particles, as shown by the results of several analytical techniques such as atomic absorption spectrometry, TGA, DSC, EDS, FTIR, and XRD. Conclusions We highlighted in the current study that the biovalorization of crab shell waste and the production of cost-effective ALP were being combined and that this was accomplished via the use of a new and innovative medium formulation design for seafood waste management as well as scaling up production of ALP on the bench-top scale.
