Abstract A synergistic effect of adsorption and photocatalysis provides a key role ensuring high degradation efficiency. In this study, nanocellulose (nC) derived from oil palm empty fruit bunch (OPEFB) via delignification followed by acid hydrolysis was combined with CuO for methylene blue (MB) removal through a two-stage process: adsorption followed by photocatalysis. The nC content varied at 5%, 15%, and 25% by mass. Structural analyses revealed successful extraction of nC from OPEFB, with particle sizes of 260–310 nm, a surface area of 2.3 m2/g, and a pore diameter of 9.5 nm. The incorporation of nC improves CuO More >

Abstract The promotion of bio-carbon for developing superior electrodes has become a trending topic in realising the practical application of supercapacitor devices. This study aimed to prepare porous carbon (PC) with a taproot fiber-like nanostructure that was decorated with self-doped oxygen. The waste of red suren leaves (RSL) was further treated using a direct heating method with the catalyst effect of ZnCl2 (0.3, 0.5, and 0.7 M) in an N2/CO2 environment at 850°C, being examined. The results showed that RSL@PC-0.5 exhibited the best amorphous carbon structure (FWHM = 0.105° and 0.182°). The specific surface area (SSA =… More >

Abstract The search for sustainable alternatives to expanded polystyrene (EPS) has led to the development of starch-based foams reinforced with agro-industrial by-product. This study aimed to evaluate the effect of sugarcane bagasse ash (SBA) content on the physical, mechanical, and water-interaction properties of cassava starch foam trays, and to determine the maximum feasible ash content that could be incorporated. Sugarcane bagasse ash was collected from the boiler air preheater. Foam trays were prepared by thermopressing using cassava starch, guar gum, magnesium stearate, glycerol, and SBA at 0%, 2%, 5%, 8%, and 11%. The trays were characterized… More >

Abstract This study investigates the valorization of mussel shell waste as a bio-derived filler in poly(L-lactic acid) (PLLA) to promote sustainable materials aligned with circular economy principles. Mussel shells, a seafood industry byproduct rich in biogenic calcium carbonate, were ground into powder and incorporated into PLLA at 10–50 wt%. The resulting composites were thoroughly characterized using scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and uniaxial tensile testing to assess morphological, chemical, thermal, and mechanical properties.

Abstract The transition toward a circular economy and zero-waste strategies has driven increasing interest in biomass-derived carbon materials as sustainable alternatives to conventional catalyst supports. Agricultural and industrial residues can be converted into porous carbons with high surface area, tunable porosity, and rich surface chemistry, enabling waste valorization and stabilization of metal species ranging from nanoparticles to single atoms. These properties support their application across heterogeneous catalysis, photocatalysis, and electrochemical systems, revealing cross-cutting opportunities among these fields. Despite these advantages, challenges remain, including feedstock heterogeneity, energy-intensive processing, scalability limitations, and the lack of standardized methodologies. This More >

Abstract Kenaf fibre has attracted increasing attention as a sustainable reinforcement material for polymer composites, particularly for applications in marine environments where lightweight structures, corrosion resistance, and environmental compatibility are essential. This review critically examines the current state of research on kenaf fibre–reinforced composites for marine applications, focusing on their mechanical performance, environmental durability, processing methods, and sustainability potential. Existing studies consistently indicate that kenaf fibres offer favourable strength-to-weight ratios, low density, and renewable characteristics, making them promising alternatives to conventional synthetic reinforcements. Surface modification techniques, including alkaline and silane treatments, have been widely reported to… More >

Abstract The environmental concerns of petroleum-based plastics, including their non-biodegradability, contribution to pollution, and reliance on finite fossil resources, have motivated growing global interest in biodegradable alternatives, with starch-based bioplastics emerging as a promising solution due to their renewability, biodegradability, cost-effectiveness, and compatibility with existing processing technologies. This review synthesizes recent developments, challenges, and analytical techniques related to starch-based bioplastics. It examines the physicochemical properties of starch, modification methods such as plasticization, blending, and chemical treatments, and key production techniques including extrusion, injection molding, and 3D printing. Mechanical, thermal, and barrier properties are evaluated through standardized More >

Abstract Most studies on kenaf fibre composites focus on the bast due to its higher fibre yield and strength, while the core is often neglected. In this work, Polylactic Acid (PLA) matrix was reinforced with both kenaf bast and core fibres at a 49:1 wt% ratio. The fibres were chemically treated and cryo-crushed to improve bonding and dispersion. Mechanical testing revealed that treated Kenaf Core Composites (KCC) exhibited comparable flexural and impact properties to Kenaf Bast Composites (KBC), with flexural strengths of 46.19 and 46.52 MPa, respectively, and impact strengths of 5.8 and 4.4 J/m.
