Background and Objective: Poor biodegradability the contamination risk of petrochemical-based plastics encouraged utilization renewable resources to replace them due their inexpensive, renewable, biodegradable compostable properties.This study aimed investigate sweet potato sourced from Indonesia as a base material bioplastic its characteristics for food packaging application.Materials Methods: Starch was extracted bioplastics prepared by mixing starch with glycerol using different...
The inherent properties of starch which are poor mechanical and its hydrophilicity that leads to long-term water absorption, fostered the incorporation additives into starch-based bioplastic enhance barrier properties. Zinc oxide (ZnO) nanoparticle as a lightweight material is biocompatible, nontoxic, cost-effective exhibit strong antibacterial activity can be considered nano reinforcement bioplastic. present work studied reinforcing effect ZnO on physical, Bioplastic was prepared by...
Excellent transparent films were prepared from bacterial cellulose (BC) sheets by solubilization of its defibrillated freeze-dried specimens in a solvent dimethylacetamide (DMAc) containing 8.0% (w/w) lithium chloride (LiCl), and their properties compared with those the native BC. Fibrillar structure BC disappeared after dissolution, film formed dissolution also loose this structure. Occurence structural transformation crystalline to amorphous state was evidenced X-ray diffraction, solid...
To address the high production cost associated with bacterial cellulose (BC) using Hestrin-Schramm (HS) medium, alternative agricultural wastes have been investigated as potential low-cost resources. This study aims to utilize pineapple core from canning industry waste a carbon source enhance growth of Komagataeibacter xylinus and characterize physical mechanical properties resulting BC. assess performance, commercial sugar at concentrations 0, 2.5, 5.0 % (w/v) was incorporated into medium....
This study reported the development and characterisation of bio-nanocomposite films based on polyvinyl alcohol (PVA) reinforced with cellulose nanofibres (CNFs) different concentrations (1–5 wt%), isolated from pineapple leaf fibre.
In this present work, a plasmonic sensor is developed through an extremely cheap cellulose-based source, widely known as food product, nata de coco (NDC). Capturing its interesting features, such innate surface roughness from naturally grown cellulose during fermentation period, the engineering and modulation of NDC fibril size properties were attempted high-pressure homogenization (HPH) treatment to obtain highly dense nanofibrils. After transformation into thin, paper-sheet form casting...
Nanocomposites of bacterial cellulose (BC) and poly(vinyl alcohol) (PVA) were prepared by cast-drying method as an easy way in producing nanocomposite films to expand the use BC. The contribution PVA nanocomposites was evaluated measurement cross-sectional surface, moisture uptake mechanical properties. Morphological analysis shows that covered a number cellulosic fibres formed denser material function addition. Based on tensile test, addition causes very slight reduction compared with...
Recycled polypropylene (RPP) and lignin represent by-products produced in enormous amounts worldwide that remain underutilized. This study used rice straw as a filler at various concentrations (0% to 70% w/w) RPP virgin (PP) composites by melt blending. Structural morphological alterations of were analyzed Fourier transform infrared (FTIR) spectroscopy scanning electron microscopy (SEM), respectively. Mechanical properties evaluated using universal testing machine (UTM). Results revealed the...
Starch–carboxymethyl cellulose (CMC) bioplastics have limited mechanical properties. Carrageenan from seaweed is a potential reinforcement material for improving the properties of bioplastics. This study aimed to determine effect Kappa (κ)-carrageenan on and thermal biodegradability starch–CMC In this study, carrageenan at concentrations 0%, 10%, 15%, 20%, 25% 30% was used. The melt-mixing process conducted 130 °C 4 min, using mixer then hot-pressing (30 kgf/cm2) 150 5 min. results indicated...
Wood and non-wood cellulose are commonly used as raw material for paper production. This study aims to produce from bacterial (BC). Due its high-water binding property, BC was rod-coated with the mixture of polyethylene oxide (PEO)/polyvinyl alcohol (PVA). The PEO varied 0.5, 1.0, 1.5, 2.0, 2.5 g (w/v) whereas use PVA 0.5 (w/v). characterized using SEM, FTIR, tensometer quality tested by Indonesia National Standard (SNI). result showed coating treatment improved mechanical, thermal, water...
Influence of wood flour and modifier contents on the physical mechanical properties flour-recycle polypropylene composites
Abstract Bacterial cellulose (BC) is one of the biopolymers which has a wide range application, from medical purposes to electrical components. Previous studies show that BC could be produced agricultural, food, and industrial waste. In this study, two kinds liquid waste were utilized as substrates for Komagataibacter xylinus produce BC, namely tofu waste, rice-washed water. The structure was determined by Scanning Electron Microscope (SEM) Fourier-transform infrared spectroscopy (FTIR)....
