AI Technical Summary

Technical Problem

The prior art is difficult to effectively utilize agricultural waste to produce sustainable high-performance biocomposites, and traditional methods have high costs, difficult processing and pollution problems, and cannot effectively replace traditional non-renewable materials.

Method used

Using a three-stage fungal growth method, lignocellulosic material is extracted from agricultural waste, and the growth of fungi under different environmental conditions forms a biological composite material, including substrate preparation, first and second growth, third growth and final Processing, using the enzyme decomposition and physical pressure of fungi to form materials with low density, flame retardancy, biodegradability and other characteristics.

Benefits of technology

Achieve low-cost and low-pollution production of biocomposite materials with multiple properties, reducing productivity losses, improving the mechanical resistance and sound absorption capacity of materials, providing sustainable alternative materials solutions that meet the requirements of the circular economy .

Abstract

The present invention belongs to the field of biotechnology, focuses on the market of sound insulation and civil engineering articles, packaging, construction and interior design, and more specifically relates to a method for producing a fungal biocomposite in two growth stages using lignocellulosic waste (husks, straw, bagasse, sawdust, etc.) from the agricultural industry as a raw material. The method is directed to providing a fungus-based biocomposite that provides a sustainable and environmentally friendly consumer product. The materials exhibit respective interesting chemical, physical and mechanical properties, making it possible to develop solutions to replace materials of non-renewable origin in the fields of civil engineering and sound insulation (replacement of expanded polystyrene, glass wool and rock wool), protective packaging (generally replacement of plastics) and architectural design / interior design (ornaments).
