Immobilization of urea on beads based on OPEFB cellulose-alginate via blending to fabricate sustained release fertilizer.

Transforming oil palm empty fruit bunches (OPEFB) waste into value-added cellulose as a reinforcement agent for eco-friendly slow-release fertilizer (SRF) composites is a strategy to achieve clean and sustainable production. OPEFB cellulose was isolated by alkalization (10 % w/v NaOH) for 1 h and bleaching (30 % v/v HO) for 1.5 h.

Enhanced properties of TEMPO-oxidized bacterial cellulose films eco-friendly non-pressurized hot water vapor treatment for sustainable and smart food packaging.

Developing a simple and environmentally friendly method to vary the physical, mechanical, and thermal properties of cellulose films is of great importance. This study aimed to characterize 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO)-oxidized bacterial cellulose (BC) films prepared using non-pressurized hot water vapor (NPHWV) method. A wet BC-pellicle that had been oxidized with TEMPO was treated with NPHWV for 60, 120, and 240 minutes, respectively.

Revolutionizing wastewater treatment: A review on the role of advanced functional bio-based hydrogels.

Water contamination poses a significant challenge to environmental and public health, necessitating sustainable wastewater treatment solutions. Adsorption is one of the most widely used techniques for purifying water, as it effectively removes contaminants by transferring them from the liquid phase to a solid surface. Bio-based hydrogel adsorbents are gaining popularity in wastewater treatment due to their versatility in fabrication and modification methods, which include blending, grafting, and crosslinking.

Nanocellulose reinforced polyvinyl alcohol-based bio-nanocomposite films: improved mechanical, UV-light barrier, and thermal properties.

This study reported the development and characterisation of bio-nanocomposite films based on the polyvinyl alcohol (PVA) reinforced with cellulose nanofibres (CNFs) of different concentrations (1-5 wt%), isolated from pineapple leaf fibre high-shear homogenisation and ultrasonication. The PVA film and bio-nanocomposite were prepared using a solution casting method. The PVA film and bio-nanocomposite samples were characterized using FE-SEM, XRD, FTIR spectroscopy, UV-vis spectroscopy in transmission mode, TGA, and DTG.

Performance of Oriented Strand Board Made of Heat-Treated Bamboo ( (Schult.) Backer) Strands.

This study aimed to analyze the effect of pre-heat treatment on bamboo strand properties and its impact on the properties of the resulting bamboo-oriented strand board (BOSB). Giant bamboo ( (Schult.) Backer) with a density of 0.

Controlling the critical parameters of ultrasonication to affect the dispersion state, isolation, and chiral nematic assembly of cellulose nanocrystals.

Cellulose nanocrystals (CNCs) are typically extracted from plants and present a range of opto-mechanical properties that warrant their use for the fabrication of sustainable materials. While their commercialization is ongoing, their sustainable extraction at large scale is still being optimized. Ultrasonication is a well-established and routinely used technology for (re-) dispersing and/or isolating plant-based CNCs without the need for additional reagents or chemical processes.

Influence of kepok banana bunch as new cellulose source on thermal, mechanical, and biodegradability properties of Thai cassava starch/polyvinyl alcohol hybrid-based bioplastic.

Bioplastics were developed to overcome environmental problems that are difficult to decompose in the environment. This study analyzes Thai cassava starch-based bioplastics' tensile strength, biodegradability, moisture absorption, and thermal stability. This study used Thai cassava starch and polyvinyl alcohol (PVA) as matrices, whereas Kepok banana bunch cellulose was employed as a filler.

Isolation and characterization of cellulose nanofibers from Agave gigantea by chemical-mechanical treatment.

Nanocellulose is a renewable and biocompatible nanomaterial that evokes much interest because of its versatility in various applications. This study reports the production of nanocellulose from Agave gigantea (AG) fiber using the chemical-ultrafine grinding treatment. Chemical treatment (alkalization and bleaching) removed non-cellulose components (hemicellulose and lignin), while ultrafine grinding reduced the size of cellulose microfibrils into nanocellulose.

Effect of heat treatment on thermal resistance, transparency and antimicrobial activity of sonicated ginger cellulose film.

Transparent film with high thermal resistance and antimicrobial properties has many applications in the food packaging industry particularly packaging for reheatable food. This work investigates the effects of heat treatment on the thermal resistance, stability of transparency and antimicrobial activity of transparent cellulose film. The film from ginger nanocellulose fibers was prepared with chemicals and ultrasonication.

Characterization of disintegrated bacterial cellulose nanofibers/PVA bionanocomposites prepared via ultrasonication.

With the increasing demand for simple, efficient, environmentally friendly preparation methods to produce cellulose nanofibers for reinforcing a biodegradable film is increased, the role of nanofibers from the pure cellulose produced by bacteria becomes more important. This work characterized bacterial cellulose nanofibers disintegrated using a high shear homogenizer. These nanofibers, in 2.
