“…Another biopolyester that can be blended with PHAs is poly(butylene adipate-co-terephthalate) (PBAT). Currently, it is obtained only partially from renewable sources, but in a short time it will be fully renewable [28], and it is biodegradable in a composting plant [35]. Consequently, it will be suitable for preparing bioplastic films, incorporating starch with mechanical properties suitable for food packaging applications [36,37].…”

In the cosmetic sector, natural and sustainable products with a high compatibility with skin, thus conjugating wellness with a green-oriented consumerism, are required by the market. Poly(hydroxyalkanoate) (PHA)/starch blends represent a promising alternative to prepare flexible films as support for innovative beauty masks, wearable after wetting and releasing starch and other selected molecules. Nevertheless, preparing these films by extrusion is difficult due to the high viscosity of the polymer melt at the temperature suitable for processing starch. The preparation of blends including poly(butylene succinate-co-adipate) (PBSA) or poly(butylene adipate-co-terephthalate) (PBAT) was investigated as a strategy to better modulate melt viscosity in view of a possible industrial production of beauty mask films. The release properties of films in water, connected to their morphology, was also investigated by extraction trials, infrared spectroscopy and stereo and electron microscopy. Then, the biocompatibility with cells was assessed by considering both mesenchymal stromal cells and keratinocytes. All the results were discussed considering the morphology of the films. This study evidenced the possibility of modulating thanks to the selection of composition and the materials processing of the properties necessary for producing films with tailored properties and processability for beauty masks.

“…Not all polymer plastics can be recycled. Hence, there has been a growing interest in biodegradable and biocompostable plastics derived from renewable material sources, which do not pollute the environment by virtue of partial or complete biotic degradation [10,11]. The development and production of biodegradable plastic materials seem to be the least expensive and most effective ways to efficiently manage plastic waste.…”

This paper presents a characterization of a plastic extrusion process and the selected properties of three biodegradable plastic types, in comparison with LDPE (low-density polyethylene). The four plastics include: LDPE, commercial name Malen E FABS 23-D022; potato starch based plastic (TPS-P), BIOPLAST GF 106/02; corn starch based plastic (TPS-C), BioComp®BF 01HP; and a polylactic acid (polylactide) plastic (PLA), BioComp®BF 7210. Plastic films with determined geometric parameters (thickness of the foil layer and width of the flattened foil sleeve) were produced from these materials (at individually defined processing temperatures), using blown film extrusion, by applying different extrusion screw speeds. The produced plastic films were tested to determine the geometrical features, MFR (melt flow rate), blow-up ratio, draw down ratio, mass flow rate, and exit velocity. The tests were complemented by thermogravimetry, differential scanning calorimetry, and chemical structure analysis. It was found that the biodegradable films were extruded at higher rate and mass flow rate than LDPE; the lowest thermal stability was ascertained for the film samples extruded from TPS-C and TPS-P, and that all tested biodegradable plastics contained polyethylene.

The sago palm stored a native starch between the trunk fiber gap. The trunk needed to be crushed into a fine size using a mechanical system. In general, the grated sago size affects the extraction efficiency, which depends on sago starch that dissolved in water during an extraction process. Therefore, the aim of this study was to determine the effect of grated sago sizes on starch recovery at different steeping periods and trunk sections. The sago trunks used were selected at three palm section (Top, Middle and Bottom). After the grating process using Sago Grater, the grated sago was dried and sieved at different sizes (2.80 mm, 2.00 mm, 1.00 mm, 0.85 mm, 0.45 mm and 0.30 mm). Furthermore, the grated sago with different sizes was steeped in sodium metabisulphite (Na 2 S 2 O 5 ) at different periods (5 mins, 24 hrs, 48 hrs and 72 hrs) for starch extraction. The results showed that the independent variables of grated size most significantly affected starch recovery (P<0.05). A substantial amount of starch could be recovered from grated sago by reducing the grated size at X<0.30 mm which was up to 58% of the extraction efficiency. The increment of the steeping period from 5 mins up to 24 hrs increased the starch recovery; however, a longer steeping period showed an insignificant difference (P>0.05). Additionally, the trunk selection also affects the starch recovery, however, it does not influence the extraction efficiency.
