Over recent years, enthusiasm towards the manufacturing of biopolymers has attracted considerable attention due to the rising concern about depleting resources and worsening pollution. Among the biopolymers available in the world, polylactic acid (PLA) is one of the highest biopolymers produced globally and thus, making it suitable for product commercialisation. Therefore, the effectiveness of natural fibre reinforced PLA composite as an alternative material to substitute the non-renewable petroleum-based materials has been examined by researchers. The type of fibre used in fibre/matrix adhesion is very important because it influences the biocomposites’ mechanical properties. Besides that, an outline of the present circumstance of natural fibre-reinforced PLA 3D printing, as well as its functions in 4D printing for applications of stimuli-responsive polymers were also discussed. This research paper aims to present the development and conducted studies on PLA-based natural fibre bio-composites over the last decade. This work reviews recent PLA-derived bio-composite research related to PLA synthesis and biodegradation, its properties, processes, challenges and prospects.

In this work, biocomposites based polylactic acid (PLA) filled with piper betle fiber (PBF) were successfully synthesized by solvent cast-film method using chloroform as the solvent. The PBF was treated with 7% NaOH. The biocomposites were loaded separately with untreated and treated PBF at 1 to 3 wt% and investigated for tensile properties and morphological of fractured surfaces. Tensile strength and modulus elasticity of biocomposites were increased with addition of betel particles and found to be higher than the matrix. Furthermore, the alkali treatment of PBF had considerably improved tensile and modulus of biocomposites compared to those of biocomposites with untreated PBF. A contrary trend was found in the case of elongation at break. However, biocomposites with treated PBF had greater elongation compared to those of biocomposites with untreated PBF. These results were identified by fracture examination with scanning electron microscopy (SEM). SEM observations showed the good bonds formed between treated PBF and PLA. This indicated by less cavity and roughness on biocomposite fractured surface with treated PBF.

Composite bioplastic is an alternative solution to solve the plastic waste problem in our environment. This is due to the composite bioplastic is one material that is environmentally friendly and easily degraded in nature. This study aims to make composite bioplastic from environmentally friendly materials, namely tapioca starch and sugarcane bagasse fiber (SBF). The addition of SBF into the tapioca matrix serves as a structural reinforcement of composites bioplastics. SBF was added by 1 wt% (from dry weight of starch basis) and kept constant for each variation of the sample. The fabrication of composite bioplastic using the solution casting method. The variation time duration of ultrasonication on composite bioplastic (tapioca starch and 1 wt% bagasse fiber) includes 0, 5, 10 and 15 min. Tensile testing, observation of fiber morphology, fracture surface characteristics, moisture absorption rate were carried out conducted by tensile test, scanning electron microscope (SEM), and moisture absorption test, respectively. The results show that the addition of ultrasonication increases the tensile strength of composite bioplastic samples. The highest tensile strength value was achieved by a sample with 15 min ultrasonication for 2.5 MPa. This result was supported by fracture morphology which shows a compact structure. In addition, the moisture absorption rate also decreases with increasing ultrasonication. Preparation and giving ultrasonication on composite bioplastic samples was highly recommended for improving the properties of the sample.

Currently, the harmful gas emission, rapid climate change, air and water pollution, and deterioration of earth's land surface are mainly produced by the aggressive utilization of petroleum-based plastic and the unmanaged garbage disposal including dumping and burning of polymeric products and substances. Many experts from throughout the globe revealed that the dumping of petroleum-based plastic and undecomposed materials is the main principle problem of environmental pollution. Hence, in order to overcome these challenging issues, biopolymers, such as starch, cellulosic-based polymer, and other biodegradable materials, are considered the most promising materials and as alternatives to non-biodegradable petroleum-based materials. This is due to their long shelf life properties such as resistance to enzymatic or chemical reaction and as they are biodegradable in nature. Starch is an abundantly available, highly biodegradable, cheap, and renewable biopolymer. However, some studies have found that the properties of starch biopolymer such as mechanical and water barrier are comparatively low than petroleum-based plastic. Therefore, nanofillers such as nanocellulose are introduced in order to overcome this issue. Nanocellulose has attracted huge attention due to its good physical and mechanical behaviors. In recent years, nanocellulose has also attracted the interest among researchers, since the technology capable to cater the environmental issues. This chapter explains the outline of current development in this particular field, including the isolation, characterization, behaviors, and various applications of nanocellulose reinforced starch biopolymer nanocomposites. Followed by explaining the distinctive properties of nanocellulose and its numerous preparation methods, an arranged introduction of various sources of nanocellulose reinforced biodegradable starch polymers is provided. Herein, nanocellulose reinforced starch biopolymer for engineering and interdisciplinary applications, comprising approaches for the transformation of various sources of cellulose to nanocellulose, and the technique of fabrication for their composites have been studied. Furthermore, the results of nanocellulose on the behavior of starch biopolymers are presented. Finally, the chapter summarizes with a new finding and innovation researches on nanocellulose reinforced starch biopolymer composites. In certain circumstances, an evaluation study was conducted between cellulose nanofiber and cellulose nanocrystals reinforced starch biodegradable polymers. Considering the vast amount of research on nanocellulose reinforced starch biopolymer composites, special highlights on such composites are allowed at the end of the review.

This study examines the effect of addition rice starch particle (RSP) in Polyethylene terephthalate (PET) based blend composites. The concentration of RSP in PET was varied at 0, 5, 10, 15 and 20 wt% with fixed percentage of sorbitol for 2 ml. The blend composites were produced by solution mixing method. All samples were tested by tensile and morphological observation after tensile test. The tensile test proves that the addition of RSP in PET increased tensile strength of blend composites. The maximum tensile strength was in 15 wt% RSP in PET for 9.79 MPa. Optical microscope displays minimum porosity with good fusion between RSP and PET. The addition of starch in polymer is suggested to reduce the percentage of using non-biodegradable polymer plastic. This research is important due to the development of biodegradable polymer.

Sugar palm (Arenga pinnata) starch and fibre are considered as a waste product of the agroindustry. The purpose of the current study is to determine the thermal, water barrier, and soil degradation properties of biodegradable plasticised sugar palm starch (PSPS) that contains sugar palm nanofibrillated celluloses (SP-NFCs) derived from sugar palm fibre. The bio-nanocomposites were fabricated by using the solution-casting method with the nanocellulose contents in the range of 0.1 wt.%–1.0 wt.%. The thermal stability, water resistance and degradation behaviour improved with increase in SP-NFCs content, due to high compatibility and strong inter-molecular hydrogen bonds formed between PSPS and SP-NFCs. PSPS/SP-NFCs bio-nanocomposites with 1.0 wt.% SP-NFCs content displayed the highest mechanical and thermal stability. Residue that was left during the TGA analysis increased as the SP-NFCs content was increased. Soil burial tests showed biodegradability resistance of the bio-nanocomposites. The following conclusions can be drawn from the present reinforcement study of SP-NFCs enhanced biodegradability, water barrier as well as thermal properties of starch polymer which extended the prospective application of environmentally-friendly polymer material. Potential applications for this eco-material are short product life cycles (plastic packaging and food container).

Interfacial bonding between cellulosic fibres and biopolymeric matrices is always an issue when it comes to blending with a different medium in composites. For example, the blending of natural or synthetic fibre with a biopolymer or synthetic polymer composite. Many research presumed that hydrophilic fibre has low interfacial bonding in composites. Nevertheless, there are several techniques that can be used to improve the interfacial bonding of hydrophobic fibre, for instance, through certain chemical treatments for the hydrophilic fibre. Chemical treatments for the fibre involve macro-sized fibre up to the nanocellulose section. The changes include physical and chemical reactions on both fibre/nanocelullose and the matrices of the composites. The transformation of interfacial bonding improvement can be observed either in macro or nano conditions. This chapter will discuss several techniques that were used to observe the changes in interfacial bonding improvement through the use of special types of equipment.

The objectives of this study were to determine the effect of Xanthosoma sagitifolium powder (XSP), mixing time and water on meat analog characters and to optimize these parameters in meat analog production using Response Surface Methodology with BoxBehnken design. Meat analog is produced from mixing XSP and concentrated soy protein using a household pasta machine. The observation was made at the range of XSP proportion 0 - 80%, mixing time 6 - 18 mins and water addition 70 - 150%. Fourier Transform Infra-red (FTIR) was employed to determine the alteration of the functional bond. The results of FTIR observation showed that the highest intensity obtained when XSP proportion, mixing time and water addition are 20%, 9 mins and 140% respectively. The experimental data obtained from the Box-Behnken design was in accordance with the second order polynomial equation. Moreover, the 3D response surface derived from mathematical models was used to optimize the production condition. The optimum production conditions are XSP proportion of 30%, water addition of 140% and mixing time of 12 mins which produced meat analog having WHC of 145.3542±5.7384%, OHC of 43.7869±7.8725% and texture of 90.32±0.37 gr/mm.

In Indonesia, starch, particularly that obtained from bengkuang (Pachyrhizus erosus), is abundant and inexpensive, thereby increasing the value of bengkuang starch, which can be mixed with bioplastic-based starch. A biocomposite comprising nanocellulose from water hyacinth (Eichhornia crassipes) and bengkuang starch was successfully fabricated using the solution casting method. Nanocellulose content in the matrix was kept constant at 1 wt%. Moreover, during fabrication, the biocomposite gel was treated in an ultrasonic bath for 0, 15, 30, and 60 min. Further, thermogravimetric analysis, moisture absorption measurements, Fourier transform infrared spectroscopy, and scanning electron microscopy were performed. The biocomposite sample vibrated for 60 min had the highest thermal stability and exhibited low moisture absorption. The soil burial test proved that this biocomposite, as opposed to 0-min vibrated samples, has a slower biodegradation rate. This result was supported by morphological evaluation after biodegradation, in which the 60-min vibrated samples showed a coarse surface and low porosity formation.

Sugar palm (Arenga pinnata) fibres and starches are considered as agro-industrial residue in the agricultural industry. This paper aims to investigate the effect of different concentrations (0–1.0 wt%) of sugar palm nanofibrillated cellulose (SPNFCs) reinforced sugar palm starch (SPS) on morphological, mechanical and physical properties of the bionanocomposites film. The SPNFCs, having a diameter of 5.5 ± 0.99 nm and length of several micrometres, were prepared from sugar palm fibres via a high-pressure homogenisation process. FESEM investigation of casting solution displayed good miscibility between SPS and SPNFCs. The FTIR analysis revealed good compatibility between the SPS and SPNFCs, and there were existence of intermolecular hydrogen bonds between them. The SPS/sPNFCs with 1.0 wt% had undergone an increment in both the tensile strength and Young’s modulus when compared with the SPS film, from 4.80 MPa to 10.68 MPa and 53.97 MPa to 121.26 MPa, respectively. The enhancement in water barrier resistance was led by reinforcing SPNFCs into the matrix, which resulted in bionanocomposites. The properties of bionanocomposites will be enhanced for short-life applications, such as recyclable container and plastic packaging through the incorporation of SPNFCs within the SPS bionanocomposites.

This paper reports on the effect of addition of cellulose nanofibers (CNF) from pineapple leaf on the properties of bengkoang starch bionanocomposite film prepared with ultrasonication. Starch, glycerol, and distilled water were mixed with 0.5, 0.1, 1.5 or 2 wt% of CNF. A gel made from this mixture was sonicated using an ultrasonic probe (600 W) for 5 min then cast in a petri dish. The addition of CNF resulted in a significant improvement (p ≤ 0.05) on the properties of the bionanocomposite. 2 wt% CNF loading led to a maximum tensile strength of 9.8 ± 0.8 MPa; 160% higher than film without fibers. The highest CNF loading resulted in the lowest moisture absorption and water vapor permeability, and highest thermal resistance of the bionanocomposite films tested. These improved characteristics were due to the ultrasonication dispersing the CNF homogeneously throughout the starch matrix and suggest that this CNF enhanced bionanocomposite could have commercial potential where there is a demand for products based on food-safe renewable raw materials.

The cellulose microfibers (CMF) from water hyacinth (WH) fiber as a filler in sago starch (SS) biocomposites was investigated. The CMF was isolated by pulping, bleaching and acid hydrolysis methods. The addition of CMF in sago matrix was varied i.e. 0, 5, 10, 15 and 20 wt%. Biocomposites were made by using solution casting and glycerol as a plasticizer. The biocomposites were also determined by tensile test, FTIR, X-Ray, thermogravimetric, SEM, and soil burial tests. The results show that the SS15CMF sample has the highest tensile strength of 10.23 MPa than those other samples. Scanning Electron Microscope (SEM) images show that the strong interaction was formed between CMF WH and matrix. Fourier Transform Infra-red (FTIR) indicated that the functional group of biocomposites was a hydrophilic cluster. The addition of CMF WH in sago starch biocomposites lead to the moisture barrier, crystallinity, and thermal stability increased; it is due to the pure sago starch film was more rapidly degraded than its biocomposites.

Sugar palm (Arenga pinnata) fibre is considered as a waste product of the agricultural industry. This paper is investigating the isolation of nanofibrillated cellulose from sugar palm fibres produced by a chemo-mechanical approach, thus opening a new way to utilize waste products more efficiently. Chemical pre-treatments, namely delignification and mercerization processes, were initially involved to extract the sugar palm cellulose. Then, mechanical pre-treatment was performed by passing the sugar palm cellulose through a refiner to avoid clogging in the subsequent process of high pressurized homogenization. Nanofibrillated cellulose was then characterized by its chemical properties (Fourier transform infrared spectroscopy), physical morphological properties (i.e. scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis), and thermogravimetric analysis. The nanofibres were attained at 500 bar for 15 cycles with 92% yield. The results showed that the average diameter and length of the nanofibrillated cellulose were found to be 5.5 ± 1.0 nm and several micrometres, respectively. They also displayed higher crystallinity (81.2%) and thermal stability compared to raw fibres, which served its purpose as an effective reinforcing material for use as bio-nanocomposites. The nanocellulose developed promises to be a very versatile material by having a huge potential in many applications, encompassing bio-packaging to scaffolds for tissue regeneration.

This paper described the tensile, thermal, and moisture absorption characteristic of polyvinyl alcohol (PVA) / bengkuang (Pachyrhizuserosus) starch blend films. The film was produced through the solution casting method. Tensile, thermogravimetric analysis and moisture test were studied to determine the tensile strength, thermal stability, and moisture absorption, respectively. The highest tensile strength (TS) was 15.86 ± 0.69 MPa for pure PVA film. This result was higher than bengkuang starch and its blends film. Tensile elongation (TE) decreased as increased bengkuang starch content in PVA. The thermal degradation of PVA film was higher 10°C than bengkuang starch films in range temperature 200-380°C. The addition of bengkuang starch in PVA also increased moisture absorption. The highest moisture absorption was in the bengkuang starch film. This blend film’s tensile, thermal, and moisture properties probably suggested it could be suitable for food packaging.

The tilt angle tool on Aluminum A5083 and Copper C11000 joint processed by Friction Stir Welding (FSW) was observed in this study. The rotation speed and transverse speed were used as a parameter process for 2500 rpm and 30 mm/min, respectively. The tensile test and microstructure observation were carried out to determine the tensile strength and metal flow on Al-Cu joint, respectively. The result shows that the highest tensile strength was in 2o tilt angle tool for 105 MPa. Its fracture surface was more close to Al and formed brittle formation.The metal flows of Al-Cu with 0o and 2o were not homogeneous and formed an agglomeration of Cu particle to Al surface.
