“…The biodegradability testing method, adapted from ISO 846/2000, was implemented under soil burial conditions using fine-grained natural active soil sourced from agricultural land in Chiang Mai Province, Thailand. Prior to testing, the soil underwent sieving to achieve a particle size of less than 2 mm [ 25 ]. MBC samples, carefully weighed with a digital laboratory scale (precision: 0.0001), were wrapped in a synthetic net before burial in soil.…”

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.

Mineral paper, a synthetic paper‐like material primarily composed of ground calcium carbonate (CaCO3) and a small amount of high‐density polyethylene (HDPE), has emerged as an important alternative to traditional paper and board due to the increasing demand for pulp and paper and the shortage of trees and fibrous material in many regions worldwide. This study aimed to investigate the impact of accelerated weathering and aerobic biodegradation on three different types of mineral papers. The specimens underwent 1000 h of accelerated weathering using a Gardner weathering device and were also buried in soil at a depth of 5 cm for 3 months with regular watering conditions for biodegradability testing. Physico‐chemical characterizations such as optical (whiteness), surface (roughness, contact angle, and paper topography), and chemical properties of the samples were studied before and after the artificial weathering and biodegradation tests. The results revealed a visible color change (darkening) in mineral papers, with an increase in HDPE content leading to a darker color after weathering and biological degradation. However, there were no significant differences in the color change between weathering and soil‐burial tests. The biodegradability test resulted in a decrease in ash content due to the demineralization process. All samples' surface roughness was reduced after weathering and biodegradation tests. The FT‐IR and EDS analyses confirmed the presence of calcium, carbon, and oxygen elements in all three samples, indicating a large amount of calcium carbonate in the mineral papers. The scanning electron microscopy (SEM) images showed the creation of micro holes and cracks on the surface of the samples after weathering and biodegradation. Overall, the soil‐burial test showed more degradation than the weathering test.Highlights The influence of weathering and biodegradation of mineral papers were studied After soil‐burial test, the ash content decreased due to the demineralization After weathering, micro cracks were created on the surface of the samples The degradation of the soil‐burial test was more than the weathering test Mineral papers most likely contain carbonate calcium and HDPE

“…The used pot is then decomposed separately. In contrast, the plantable bio-pot can be transplanted altogether into a larger container or garden soil without disturbing the root system of plant seedling or a young plant, and it returns nutrients to the soil by decomposing, leaving no waste (Sandak et al 2019;Tomadoni et al 2020). Generally, a plantable bio-pot is produced from lignocellulosic materials, such as agro-industrial wastes and agricultural residues.…”

The oil palm trunk contains great nutrients for plant growth, and its supporting cells are mostly parallel to the centerline. This study investigated the fabrication of a plantable bio-pot from 5 mm thick sheets of oil palm trunk. The effects of the three zones in the trunk (outer, middle, and inner) and the pressing mold temperature in the range from 160 °C to 200 °C on characteristics of a bio-pot were evaluated. The results demonstrated that the outer zone of an oil palm trunk with 200 °C molding temperature had the highest ultimate compression load, and the pot shape appeared stable after soaking in water for 24 h, showing 105% water absorption. The changes to oil palm trunk chemistry caused by elevated temperature contributed to the mechanical properties and improved durability. The oil palm trunk plantable bio-pots facilitated germination of chili and eggplant seeds. The leaf number, leaf greenness, plant height, and total dry biomass had no significant difference between using the oil palm trunk bio-pot and a plastic pot for a seedling of either of these plants.
