Valorization of Engineered Bamboo-Based Thermal Insulating Building Materials: A Journey from Nature to Nature Protection—A Case Study

The cultivation of bamboo enriches mother earth due to its ability to grow in barren and other old places. It contributes to a crucial natural-based strategy for reducing carbon emissions and combating global warming. It gathers thanks to its capacity to increase ethane. The potential for thermal insulating materials made of bamboo to protect the environment is highlighted in the current review. The first section focuses on bamboo’s significance and inherent potential as a thermally insulating material. Numerous documented bamboo-based thermal insulating materials have been the subject of significant scientific developments. Significant scientific advancements have been focused on preparing various bamboo-based thermal insulating materials. Different bamboo species and appropriate raw materials like guadua, bamboo paper sludge, moso bamboo, floating beads of fly ash, bamboo fiber, enteromorpha fiber, calcium carbonate, active silicon micropower, and re-dispersible latex powder are reported to develop thermal insulating material. They created several bamboo products, including multilayer panels, thermal insulation walls, bamboo fiber building materials, and boards. The advanced bamboo composite sample was tested for detailed characterization using SEM, EDX, mechanical strength, and water absorption studies. At 20, 50, and 100 °C, the thermal conductivity was evaluated at various temperatures and was found to be 0.166, 0.140, and 0.120 W/mK, respectively. According to the results, the composite exhibits less heat conductivity at 100 °C than at 20 °C or 50 °C, making it a superior thermal insulator material. The low values obtained for the thermal conductivities of bamboo composites make them utilizable for thermal insulating applications. The conclusions, anticipated viewpoints, and suggestions on the bamboo-based thermal insulating material for environmental protection are highlighted in the later sections. Bamboo can be adapted as a resource medium for creating thermal insulating material. This will provide the most current events in the scientific community to merge new approaches with new methodologies. Consequently, it is strongly supported as a pathway from nature to the protection of nature.
