Abstract Interest in the use of cellulose nanomaterial’s continues to grow, both in research and industry, not only due to the abundance of raw materials, low toxicity and sustainability, but also due to the attractive physical and chemical properties that make nanocelluloses useful for a wide range of end-use applications. Among the large number of potential uses, and nanocelluloses modification and processing strategies, the chosen topic of this review focuses exclusively on plant-derived cellulose microfibers/nanofibers (CNF) and cellulose nanocrystals (CNC) processed into 2D structures—nanopapers and nanofilms—fabricated as self-standing films or applied as coatings. The end uses… More >

Abstract Composites made from biopolymers and natural fibers are gaining popularity as alternative sustainable structural materials. Biopolyesters including polylactic acid (PLA), polybutylene succinate (PBS), and polyhydroxyalkanoate (PHA), when mixed with natural fibers such as kenaf, hemp, and jute, provide an environmentally acceptable alternative to traditional fossil-based materials. This article examines current research on developments in the integration of biopolymers with natural fibers, with a focus on enhancing mechanical, thermal, and sustainability. Innovative approaches to surface treatment of natural fibers, such as biological and chemical treatments, have demonstrated enhanced adhesion with biopolymer matrices, increasing attributes such as… More >

Abstract The use of agricultural residues in biocomposite production has gained increasing attention, driven by several benefits. Converting agricultural by-products into bio-based materials within a circular economy represents a sustainable strategy to mitigate lignocellulosic waste, reduce reliance on fossil resources, and lower environmental pollution. This approach also creates economic opportunities for rural African communities by generating diverse income sources for workers in collection, processing, and manufacturing. As a result, the integration of agricultural residues into biocomposites production not only addresses environmental concerns but also fosters economic growth and supports rural development. In this review, five biomasses… More >

Abstract Polylactic acid (PLA), a biodegradable polymer, exhibits superior mechanical strength and processability. However, its broader adoption is hindered by inherent brittleness, low hydrophilicity, and sluggish crystallization kinetics. Chitosan (CS), a natural polysaccharide renowned for its biocompatibility and biodegradability, offers potential to address these limitations. While both materials have garnered significant attention in materials science, research on their integration via melt blending and the resulting performance enhancements for food-contact plastics remains understudied. This research comprehensively explores how different levels of CS content, from 0% to 10%, impact the characteristics of chitosan/polylactic acid (CS/PLA) composites. It specifically… More >

Abstract Interfacial compatibilization is essential to generate compatible blend structures with synergistically enhanced properties. However, the effect of molecular structure on the reactivity of compatibilizers is not properly known. This study investigates the compatibilization effect of multifunctional, epoxy-based Joncryl chain extender in blends of polylactide (PLA) and polybutylene adipate-co-terephthalate (PBAT) using PLA with varying D-lactide contents and molecular weights. These PLAs were high molecular weight amorphous PLA (aPLA) with D-content of 12 mol% and semi-crystalline PLA (scPLA) grades with D-contents below 1.5 mol% at both high (h) and low (l) molecular weights. The reactivity of Joncryl… More >

Abstract In this study, Opuntia ficus-indica cladode powder (OFIC), locally sourced from Rabta in Tunis, was utilized as a novel, eco-friendly adsorbent in both raw and iron(III) chloride-modified forms. The presence of iron in the modified material was confirmed by X-ray fluorescence spectroscopy (XRF). The neat and modified biomass were characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM), and their usefulness as adsorbent for cationic Neutral Red (NR) and anionic Congo Red (CR) dyes were explored under batch conditions. Equilibrium studies revealed that the iron-modified Fe(OH)_x@Cellulose adsorbent exhibited… More >

Abstract Nowadays, the development of effective bioplastics aims to combine traditional plastics’ functionality with environmentally friendly properties. The most effective and durable modern bioplastics are made from the edible part of crops. This forces bioplastics to compete with food production because the crops that produce bioplastics can also be used for human nutrition. That is why the article’s main focus is on creating bioplastics using renewable, non-food raw materials (cellulose, lignin, etc.). Eco-friendly composites based on a renewable bioplastic blend of polybutylene adipate-co-terephthalate, corn starch, and poly(lactic acid) with reed and hemp waste as a filler.… More >

Abstract Adsorbents with three-dimensional porous structures have gained widespread attention due to their unique characteristics, including a large surface area, high porosity, and excellent absorption capacity. One of the products is the wood sponge. The key to successfully producing wood sponges lies in an optimal multistage delignification process, which is particularly influenced by wood species, solvent, time, and temperature. The aim of this research was to analyze the characteristics of wood sponge derived from sengon wood (Falcataria moluccana Miq.) after multistage delignification. The process involved delignification using NaOH and Na₂SO₃ solutions at 100°C for 8, 9 and 10… More >
