Abstract The development of actuators based on ionic polymers as soft robotics, artificial muscles, and sensors is currently considered one of the most urgent topics. They are lightweight materials, in addition to their high efficiency, and they can be controlled by a low power source. Nevertheless, the most popular ionic polymers are derived from fossil-based resources. Hence, it is now deemed crucial to produce these actuators using sustainable materials. In this review, the use of ionic polymeric materials as actuators is reviewed through the emphasis on their role in the domain of renewable materials. The review… More >

Abstract The main objective of the study was to prepare a highly active antimicrobial remedy by combining active agents such as tannic acid and silver nanoparticles, which are usually used separately. This was achieved by applying a coating of 11 alternating layers of an insoluble complex of tannic acid with polyvinyl alcohol on paper by the layer-by-layer approach, on the surface of which uniformly distributed spherical silver nanoparticles of uniform size, mainly 20–30 nm, were synthesized by in situ reduction using tannic acid, which also acts as a stabilizer, or an external reducing agent, which prevented polyphenol More >

Abstract In the past two decades, nanocellulose has become an innovative material with unique properties. This substance has exceptional mechanical strength, an extensive surface area, and biodegradability. Collaborative integration of nanocellulose offers a more environmentally friendly solution to the current limitations by substituting carbon. Due to its versatility, nanocellulose is commonly employed in various industrial sectors, including paints, adhesives, paper production, and biodegradable polymers. Such versatility enables the creation of customized structures for potential use in emulsion and dispersion applications. Given its biocompatibility and nontoxicity, nanocellulose is particularly well-suited for biomedical purposes such as tissue engineering, More >

Abstract Bio-oil is a renewable fuel that can be obtained from biomass waste, such as empty palm fruit bunches, sugarcane bagasse, and rice husks. Within a biorefinery framework, bio-oil had not met the standards as a fuel due to the presence of impurities like corrosive phenol. Therefore, the separation of phenol from bio-oil is essential and can be achieved using the extraction method. In this study, biomass wastes (empty fruit bunches of oil palm, sugarcane bagasse, and rice husk) were pyrolyzed in a biorefinery framework to produce bio-oil, which was then refined through liquid-liquid extraction with… More >

Abstract Biodegradable plastics are types of plastics that can decompose into water and carbon dioxide the actions of living organisms, mostly by bacteria. Generally, biodegradable plastics are obtained from renewable raw materials, microorganisms, petrochemicals, or a combination of all three. This study aims to develop an innovative bioplastic by combining chitosan and lignin. Bioplastic was prepared by casting method and characterized by measuring the mechanical properties like tensile strength, Young’s modulus, and elongation at break. The chemical structure, together with the interactions among chitosan and lignin and the presence of new chemical bonds, were evaluated by… More >

Abstract This research aims to investigate the potential of a plant cellulose developed from Opuntia ficus-indica (OFI) cladode as a sustainable and renewable adsorbent for the removal of neutral red (NR), a cationic dye pollutant, from aqueous environments. Analysis of raw and treated OFI using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR) demonstrated the successful extraction of type cellulose. The Brunauer–Emmett–Teller (BET) analysis of the nitrogen adsorption-desorption isotherm revealed an improved specific surface area of 12.4 m²/g after treatment. A systematic study of key parameters in batch adsorption experiments revealed removal rates… More >

Abstract The use of additive manufacturing techniques in the development of unconventional materials can help reduce the environmental impact of traditional construction materials. In this paper, the properties of a 3D-printed biocomposite were evaluated. Biofilaments obtained by mixing pulverized bamboo fibers with polylactic acid (PLA) resin were extruded during the manufacturing process. To assess the effect of incorporating plant fibers, an analysis was conducted on the morphology, elemental chemical composition, crystallinity index, principal functional groups, thermal stability, surface roughness, microhardness, density, tensile strength, elastic modulus, and strain percentage of reinforced samples. The results were compared with… More >

Abstract The selection of carbon sources and the biosynthesis of polyhydroxybutyrate (PHB) by the Azotobacter vinelandii N-15 strain using renewable raw materials were investigated. Among the tested substrates (starch, sucrose, molasses, bran), molasses as the carbon source yielded the highest PHB production. The maximum polymer yield (26% of dry biomass) was achieved at a molasses concentration of 40 g/L. PHB formation was confirmed via thin-layer chromatography, gas chromatography and Fourier transform infrared spectroscopy. Composite films based on PHB, polylactic acid (PLA), and their blends were fabricated using the solvent casting. The biodegradation of these films was studied More >

Abstract In this study, the casting process is used to fabricate modified polyvinyl alcohol (PVA), starch (S), and carboxymethyl cellulose (CMC) polymer blend films (PVA/S/CMC) loaded with various concentrations of iron-doped carbon quantum dots (Fe-CQDs) and denoted as (PVA/S/CMC@Fe-CQDs). A one-step microwave strategy was employed as a facile method to prepare Fe-CQDs. Through a series of characterization techniques, fourier-transform infrared (FTIR) spectroscopy, x-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) have been used to show the successful integration of Fe-CQDs into the PVA/S/CMC matrix. Loading the synthesized Fe-CQDs to the polymeric matrix significantly enhanced the… More >

Abstract The increase in wood and wood-based products in the construction and furniture sectors has grown exponentially, generating severe environmental and socioeconomic impacts. Particleboard panels have been the main cost-benefit option on the market due to their lightness and lower cost compared to solid wood. However, the synthetic adhesives used in producing traditional particleboard panels cause serious harm to human health. Developing particleboard panels with fibrous waste and natural adhesives could be a sustainable alternative for these sectors. The work aimed to create particleboards with fibrous wastes from the pseudostem of the banana tree (Musa paradisiaca) and… More >
