Special Issue Information

Dear Colleagues,

The increasing global demand for sustainable materials has positioned cellulose and wood-based composites as pivotal contributors to modern science and industry. This Special Issue explores the latest advancements in the design, synthesis, and application of these renewable materials. We welcome contributions that address topics such as innovative methods for cellulose extraction and modification, the development of high-performance wood-based composites, and their applications in fields ranging from construction to nanotechnology. Studies that focus on the enhancement of material properties, such as mechanical strength, thermal stability, and biodegradability, are particularly encouraged. Additionally, we invite research that addresses the integration of artificial intelligence and machine learning for material optimization, as well as lifecycle assessments that ensure environmental sustainability. This Special Issue aims to provide a comprehensive platform for researchers, engineers, and industry professionals to share insights that advance the field of cellulose and wood-based composite technologies.

This study investigates the sustainable use of Eucalyptus spp. bark through different chemical (hydrothermal, acid, alkaline, and bleaching) and physical (milling) pretreatments in the production of sustainable films. Valorization of agro-industrial residues and the demand for sustainable materials pose challenges for environmentally responsible solutions. Eucalyptus spp. bark, rich in cellulose, hemicellulose, and lignin, is a promising source for creating sustainable materials like films. In this study, the use of chemical and physical treatments aims to optimize biomass extraction and improve the chemical, thermal, mechanical, and optical properties of the films. The films showed an excellent light barrier capacity, with a transmittance below 1%. Crystallinity indices varied with the pretreatment: 8.15% for hydrothermal, 7.01% for alkaline, 7.63% for acid, and 10.80% for bleaching. The highest crystallinity value was obtained through bleaching, by removing amorphous components like lignin and hemicellulose. The alkaline pretreatment yielded stronger films (maximum stress of 8.8 MPa, Young’s modulus of 331.3 MPa) owing to the retained lignin and the hemicellulose reinforcing the material. This study contributes to the field of sustainable development by converting residues into valuable materials and by advancing the circular economy. The films’ specific properties make them suitable for applications like sustainable packaging, addressing environmental and industrial challenges. Full article
