Abstract Saccharification of lignocellulosic wastes is the bottleneck of different bio-based chemical industries. Using enzymes for saccharification of lignocellulosic materials has several advantages over using chemicals. In the current work, the application of the Maximyze® enzyme system, which is industrially used in papermaking, was investigated in the saccharification of paper sludge and fiber dust wastes from the tissue paper industry. For optimizing the saccharification process, the effects of the consistency %, enzyme loading, and incubation time were studied and optimized using the Response Surface Methodology. The effect of these factors on the weight loss of paper… More > Graphic Abstract

Abstract This study prepared and characterized amphiphilic carboxymethyl cellulose stearate (CMCS) recycled from sugarcane bagasse agro-waste (SB). The Fourier-transform infrared (FTIR) analysis confirmed cellulose, carboxymethyl cellulose (CMC), and CMCS structures, with CMCS showing increased H-bonding. X-ray diffraction analysis (XRD) revealed reduced crystallinity in CMC and CMCS. CMCS exhibited a hydrophobic nature but dispersed in water, enabling nanoemulsion formation. Optimal nanoemulsion was achieved with CMCS1, showing a particle size of 99 nm. Transmission electron microscopy (TEM) images revealed CMC’s honeycomb structure, transforming into spherical particles in CMCS1. Antimicrobial tests demonstrated strong activity of CMCS formulations against Escherichia coli More >

Abstract Wood, recognized as a renewable and environmentally sustainable material, plays a crucial role as an alternative energy resource within the construction industry. However, it is highly susceptible to mold and decay fungi, which can lead to surface discoloration and potentially compromise the structural integrity of wood. The advancement of nanotechnology has introduced innovative strategies for wood protection, enhancing its performance while imparting additional properties. Various approaches including nanosized metals, polymer nanocomposite and coating treatments are actively being explored in this field. Furthermore, integrating bio-based materials with nanotechnology offers a green and sustainable method for wood More >

Abstract The work deals with cellulose paper filled with nanocellulose and SrAl₂O₄:Eu,Dy oxide phosphor. It was found that both nanocellulose and oxide improve the tensile strength of the composites obtained. The samples with the oxide demonstrate a long-lasting photoluminescence (PL) under sunlight and ultra-violet (UV) illumination. Room-temperature the PL spectra reveal a wide multicomponent band spreading over all the visible spectral regions. The short-wavelength part of the band is ascribed to the cellulose-related luminescence, while the long-wavelength PL component with maxima near 540 nm corresponds to the luminescence of the SrAl₂O₄:Eu,Dy phosphor. The dependency of the PL… More > Graphic Abstract

Abstract This review is composed of three main parts each of which is written by well-known top specialists that have been, in a way or other, also the main participants of the majority of the developments reported. Thus, after a general part covering the grand lines and more in-depth views of more recent tannin, lignin, carbohydrate and soy bioadhesives, some mix of the other bio raw materials with soy protein and soy flour and some other differently sourced bioadhesives for wood, this review presents a more in-depth part on starch-based wood adhesives and a more in-depth… More > Graphic Abstract

Abstract Alternative methods for biodiesel purification that focus on ease of operation, cost reduction, and elimination of contaminated residues or that are easier to treat have received more attention. The dry wash route was used as an alternative to the wet route in biodiesel production. Filter membranes were developed based on cellulose nanofibers as the matrix and sugarcane bagasse fibers or soy hulls, as reinforcement to the matrix, before and after two chemical treatments (carboxymethylation and regeneration with sulfuric acid). The filters were characterized by permeability capacity, morphology, wettability, porosity, SEM and mechanical properties. The filtered… More >

Abstract This review aims to identify the assets and limitations of Dabema (Piptadeniastrum africanum) as a sustainable alternative to traditional timber species for furniture and construction applications. Dabema is characterized by its high density and dimensional stability, meeting ASTM (American Society for Testing and Materials) standards for mechanical strength, which is essential for promoting its use. However, its limited availability in trade and ingrained habits of use are obstacles to its widespread commercialization. In addition, thermal and oleothermal treatments have shown great potential for improving the characteristics of this wood, although they require ongoing optimization and rigorous More > Graphic Abstract

Abstract Herein, cure characteristics, morphology, and mechanical properties of natural rubber filled with activated carbon-based materials were investigated. Carbon-based materials were prepared from bagasse, coffee grounds and pineapple crowns by the pyrolysis method at temperatures in the range of 300°C. As-synthesized carbon materials were characterized by optical microscopy (OM), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR) to analyze size distribution, morphology, and functional groups, respectively. OM and SEM analysis revealed that particles, flakes, and a small quantity of fiber-like carbon were obtained using bagasse and pineapple crown as raw materials, while honeycomb-like carbon materials… More > Graphic Abstract
