Mechanical Physicial Properties of Chlorella-PVA based Bioplastic with Ultrasonic Homogenizer
Open accessAbstract
Public demand for environmentally friendly packaging material especially in food industry is increasing. One of the many solutions invented for this problem is the development of biodegradable plastic. Biopolymer can be mixed with synthetic polymer to produce biodegradable films with properties suitable for varying applications. This study examines the mechanical physical properties of Chlorellapolyvinyl alcohol (PVA) based bioplastic by pre-treating the Chlorella powder with ultrasonic homogenizer. Variation of Chlorella concentration and temperature was done during the ultrasonication. Before being used as bioplastic base, pre-treated Chlorella with different concentrations were equated. Bioplastic films were then prepared with the pre-treated Chlorella powder and PVA using solvent casting method. Mechanical physical properties of the pre-treated Chlorella films then compared with non pretreated Chlorella film as control. Mechanical test shows the increasing of bioplastic tensile strength up to 15,3 kgf/cm 2 and elongation percentage up to 99,63%. Field emission scanning electron microscopy test shows the increasing of bioplastic homogenity and smoother surface with less pores. Fourier transform infrared analysis shows that there are crosslinkages between Chlorella and PVA. Thermal analysis by thermogravimetric analysis shows ultrasonication creates a more compact linkages. The performance of the film could suggest its potential as an eco-sustainable food packaging plastic material.

Chlorella sp. and Spirulina (Arthrospira) sp. demonstrate promise in biopolymer production.
“Chlorella sp. and Spirulina (Arthrospira) sp. demonstrate promise in biopolymer production [193,194,195,196].”
From Emerging Applications of Chlorella sp. and Spirulina (Arthrospira) sp. (2023) · cites this paper as [196]
The Introduction describes microalgae as promising sources for bioplastic production, and the Conclusions report potential for Chlorella–PVA films. The paper does not evaluate Spirulina; it appears only in the title of a cited reference. This source therefore supports the Chlorella part, but not the full two-species claim. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
