Mycelium-based bio-composites (MBCs) represent a sustainable and innovative material with high potential for contemporary applications, particularly in the field of modern interior design. This research investigates the fabrication of MBCs for modern interior materials using agro-industrial wastes (bamboo sawdust and corn pericarp) and different fungal species. The study focuses on determining physical properties, including moisture content, shrinkage, density, water absorption, volumetric swelling, thermal degradation, and mechanical properties (bending, compression, impact, and tensile strength). The results indicate variations in moisture content and shrinkage based on fungal species and substrate types, with bamboo sawdust exhibiting lower shrinkage. The obtained density values range from 212.31 to 282.09 kg/m3, comparable to traditional materials, suggesting MBCs potential in diverse fields, especially as modern interior elements. Water absorption and volumetric swelling demonstrate the influence of substrate and fungal species, although they do not significantly impact the characteristics of interior decoration materials. Thermal degradation analysis aligns with established patterns, showcasing the suitability of MBCs for various applications. Scanning electron microscope observations reveal the morphological features of MBCs, emphasizing the role of fungal mycelia in binding substrate particles. Mechanical properties exhibit variations in bending, compression, impact, and tensile strength, with MBCs demonstrating compatibility with traditional materials used in interior elements. Those produced from L. sajor-caju and G. fornicatum show especially promising characteristics in this context. Particularly noteworthy are their superior compression and impact strength, surpassing values observed in certain synthetic foams multiple times. Moreover, this study reveals the biodegradability of MBCs, reaching standards for environmentally friendly materials. A comprehensive comparison with traditional materials further supports the potential of MBCs in sustainable material. Challenges in standardization, production scalability, and market adoption are identified, emphasizing the need for ongoing research, material engineering advancements, and biotechnological innovations. These efforts aim to enhance MBC properties, promoting sustainability in modern interior applications, while also facilitating their expansion into mass production within the innovative construction materials market.

“…An uneven, fibrous structure was observed in the cro sectional images of the uncoated papers. However, there was no vacant space on the s face of the coated paper because the pores of the cellulose fibers were filled with PBAT the paper was coated and the surface filled with PBAT, a smooth and uniform surface w observed, providing an excellent degree of coverage over the paper with no visible por indicating that the polysaccharides with the rubber coating layer were compatible w the paper and adhered easily to the paper surface [23,54]. These results justify the O and WVTR properties of this packaging material.…”

In this research work, a coated paper was prepared with poly (butylene adipate-co-terephthalate) (PBAT) film to explore its use in eco-friendly food packaging. The paper was coated with PBAT film for packaging using hot pressing, a production method currently employed in the packaging industry. The coated papers were evaluated for their structural, mechanical, thermal, and barrier properties. The structural morphology and chemical analysis of the coated paper confirmed the consistent formation of PBAT bi-layered on paper surfaces. Surface coating with PBAT film increased the water resistance of the paper samples, as demonstrated by tests of barrier characteristics, including the water vapor transmission rate (WVTR), oxygen transmission rate (OTR), and water contact angle (WCA) of water drops. The transmission rate of the clean paper was 2010.40 cc m−2 per 24 h for OTR and 110.24 g m−2 per 24 h for WVTR. If the PBAT-film was coated, the value decreased to 91.79 g m−2 per 24 h and 992.86 cc m−2 per 24 h. The hydrophobic nature of PBAT, confirmed by WCA measurements, contributed to the enhanced water resistance of PBAT-coated paper. This result presents an improved PBAT-coated paper material, eliminating the need for adhesives and allowing for the fabrication of bi-layered packaging.

Paper and paperboard are cellulosic materials used to manufacture food packaging. However, their low resistance to water and fat, as well as their poor barrier properties have limited their packaging applications as food contact materials. The current review analyses the use of biopolymeric coatings as an alternative to improve surface and barrier properties in paper and paperboard with focus in food sector application. Advances in coated paper (board) can be classified into three groups: (1) coatings manufactured with a single biopolymer; (2) coatings manufactured with composite biopolymers; and (3) biopolymeric coatings incorporated with bioactive molecules or nanoparticles. The use of a single or composite biopolymer coating improved the mechanical, barrier properties, and grease resistance. In contrast, the use of chemical compounds and nanoparticles has imparted active properties (antibacterial and ethylene scavengers) in the resulting coating paper (board). The water vapour transmission rate has been reduced with the use of biopolymeric coatings. Future studies should focus on applying coated paper (board) in foods with a special interest in food self‐life, migration, and toxicity.
