Summary
Conventional wood-based composites are commonly manufactured using synthetic formaldehyde-based adhesives derived from non-renewable petroleum resources. Despite their good bonding performance, these adhesives are associated with environmental and health concerns due to formaldehyde emissions and limited biodegradability. Consequently, increasing attention is being devoted to the development of environmentally friendly wood-based composites based on renewable raw materials and sustainable technologies.
Potential strategies for reducing the environmental impact of wood composites include the application of formaldehyde scavengers, low-emission adhesive systems, and various pre-treatment and post-treatment methods. In addition, recycled wood, agricultural residues, and lignocellulosic by-products such as hemp shives, straw, bamboo, and bagasse are increasingly explored as alternative raw materials within the framework of a circular bioeconomy. Recent advances in nanotechnology have also enabled the development of composites with enhanced mechanical performance, dimensional stability, and durability through the incorporation of nanomaterials. Furthermore, thermoplastic-based and binderless composites represent promising alternatives to conventional formaldehyde-bonded systems. Various chemical and physical modification methods are being investigated to improve compatibility and bonding performance in such materials.
This Special Issue welcomes high-quality original research and review articles focused on sustainable materials, innovative processing technologies, recycling approaches, and environmentally friendly wood and bio-based composites.
