Abstract This study investigated the development of mycelium-based biofoams as sustainable cushioning materials using Pleurotus ostreatus and Lentinus squarrosulus, combined with different sawdust substrates, and subjected to various pressing methods. The results indicated significant effects of mushroom species, sawdust type, and pressing method on the properties of biofoams. Growth rate, morphology, chemical composition, physical and mechanical properties, water resistance, and cushioning factor were evaluated. The results indicated that Lentinus squarrosulus (LS) exhibited faster growth rates (up to 14.37 mm/day) and produced biofoams with superior properties compared to Pleurotus ostreatus (PO). Core wood (CW) sawdust generally resulted in biofoams with lower… More >

Abstract As oil is now an important resource for the survival and development of mankind, the consumption of oil continues to increase each year, and there have been a number of major oil spills in history, such as the oil spill from the Deepwater Horizon drilling rig. Therefore, oil spills during storage and transportation have become an issue of serious concern. Current methods such as incineration and chemical methods cause secondary environmental pollution and fail to enable resource recovery. The adsorption method by porous materials has attracted worldwide attention due to its simplicity, portability, and efficiency.… More >

Abstract The deficiencies of popular phthalate plasticizers (ready migration from a polymer matrix into which they have been incorporated, flammability, environmental pollution, human health risks) have stimulated efforts to develop new effective, nonmigrating, low-cost, nontoxic replacements. In the main, these have been based on readily-available, nontoxic biobased precursors. Some, including those prepared from plant oils, have been generated from biomaterials themselves. However, the more numerous and generally more effective have been generated from discrete compounds produced from various biomaterials. Several structural features of effective plasticizers have been recognized. Polar functionality is required to assure compatibility with More >

Abstract Commercial lithium-ion batteries (LIBs) use polyolefins as separators. This has led to increased research on separators composed of renewable materials such as cellulose and its derivatives. In this study, the ionic conductivity of cellulose acetate (CA) polymer electrolyte membranes was enhanced via plasticization with citric acid and succinonitrile. The primary objective of this study was to evaluate the effectiveness of these plasticizers in improving cellulose-based separator membranes in LIBs. CA membranes were fabricated using solution casting technique and then plasticized with various concentrations of plasticizers. The structural, thermal, and electrochemical properties of the resulting membranes… More >

Abstract With growing environmental concerns and the depletion of oil reserves, the need to replace synthetic fibres with sustainable alternatives in composite materials has become increasingly urgent. This study investigates the potential of Leptadenia pyrotechnica fibre as a sustainable reinforcement material in hybrid composites alongside E-glass fibres. The primary objectives are to assess these hybrid composites’ mechanical properties, structural integrity, and performance. To achieve this, Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were employed to analyze the microstructure and chemical composition of the composites. At the same time, mechanical testing focused on properties such… More >

Abstract This study investigated the efficiency of activated carbon from Pangium edule shells for removing phosphate from aqueous solution. The adsorption capacity of the synthesized activated carbon was determined to be 19.8392 mg g⁻¹. Various isotherm models were used to analyze the adsorption process, Henry, Freundlich, SIP, and Halsey isotherm fitting showed r² values close to 1.0. These isotherms indicated a combination of physisorption and chemisorption mechanisms, with heterogeneity and multilayer formation playing important roles. A pseudo-second-order model described the adsorption kinetics well, suggesting chemisorption as the dominant mechanism with an r² value of 1.0 and a rate constant… More >

Abstract Over the last decade, the oriented strand board (OSB) market presented meaningful growth. However, as a wood-based product, because of its anatomical structure and chemical composition, OSB can be damaged by biodeterioration agents. Given that, the biodeterioration of OSB panels must be investigated to improve its durability. In this way, this work analyses the biological resistance against termites (Cryptotermes brevis and Nasutitermes corniger) of heat-treated OSB panels made with Eucalyptus wood glued with vegetable-based polyurethane-an eco-friendly and sustainable adhesive derived from castor oil. Various panels were produced with different layers compositions (face:core:face of 25:50:25 and 30:40:30) in wood… More >

Abstract The isolated hydrophilic black alder (Alnus glutinosa) bark extractives were characterized in terms of component and functional composition and converted at 150°C–170°C into liquid green polyols using solvent-free and low-toxic base-catalyzed modification with propylene carbonate (PC). FTIR spectroscopy, HP-LC, GC, GPC, and wet chemistry methods were used to characterize the starting constituents, intermediate and final products of the reaction and to monitor the different pathways of PC conversion. The reaction of extractives as well as the model compounds, including catechol, xylose, PEG 400, and benzoic acid, with PC indicated the ability of OH groups of different… More >
