“…Depending on the application, growth can continue within formworks [ 38 , 39 ]. Some studies explored the extrusion of the substrate mixtures through additive manufacturing [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ]. Some of the parameters that affect the resulting material properties in this phase are the duration of growth, environmental conditions such as temperature and relative humidity, and CO 2 concentration [ 49 , 50 ].…”

Mycelium-based composites (MBC) are biodegradable, lightweight, and regenerative materials. Mycelium is the vegetative root of fungi through which they decompose organic matter. The proper treatment of the decomposition process results in MBC. MBC have been used in different industries to substitute common materials to address several challenges such as limited resources and large landfill waste after the lifecycle. One of the industries which started using this material is the architecture, engineering, and construction (AEC) industry. Therefore, scholars have made several efforts to introduce this material to the building industry. The cultivation process of MBC includes multiple parameters that affect the material properties of the outcome. In this paper, as a part of a larger research on defining a framework to use MBC as a structural material in the building industry, we defined different grades of MBC to address various functions. Furthermore, we tested the role of substrate mixture and the cultivation time on the mechanical behavior of the material. Our tests show a direct relationship between the density of the substrate and the mechanical strength. At the same time, there is a reverse relation between the cultivation time and the material mechanical performance.

“…Specifically, developing nations present a huge opportunity in terms of the agricultural, wood waste being and municipal waste, that can be used for the fabrication of fungal biocomposites. In addition to the usage of raw materials from agricultural cellulose-based materials, studies have also reported the usage of waste materials like egg cartons, cardboard, newspaper, and paper cups [63]. Lately in India, there is a significant increase in the cultivation of hemp which has relatively less water requirement.…”

Plastic waste management has become a major problem in the present times, and many countries are struggling to deal with it. The situation has become a crisis in developing nations due to a lack of proper waste management, resources, technology, and political will. The extensive usage of foam-based packaging materials such as Styrofoam as a secondary packaging material has led to environmental pollution both in land and water, in developing countries. It is important to address this problem using a sustainable approach such as biomimetic manufacturing. One such solution that is present in developed nations is mycelium-based packaging, wherein the agricultural and industrial-based cellulose waste is converted into a biocomposite with the help of a fungi root network. Such a process has the potential to convert biomass into useful products but also has an indirect effect on pollution reduction by eliminating stubble burning in nations like India. In this review, we examine the details of the manufacturing process, properties, advantages, and limitations of such composite materials. A comparison of the present status of such materials produced in the market by some of the companies across the world is presented. Finally, the challenges involved with such materials and the future directions are discussed.

“…For instance, a living composite made with Ganoderma resinaceum responds to pressure by changing its electrical activity [ 17 ]. Moreover, mycelium can be maintained active to enable production of large size mycelium composites, for instance to make mycelium connections between mycelium panels [ 15 , 18 , 19 ].…”

Sustainable fungal materials have a high potential to replace non-sustainable materials such as those used for packaging or as an alternative for leather and textile. The properties of fungal materials depend on the type of fungus and substrate, the growth conditions and post-treatment of the material. So far, fungal materials are mainly made with species from the phylum Basidiomycota, selected for the mechanical and physical properties they provide. However, for mycelium materials to be implemented in society on a large scale, selection of fungal species should also be based on a risk assessment of the potential to be pathogenic, form mycotoxins, attract insects, or become an invasive species. Moreover, production processes should be standardized to ensure reproducibility and safety of the product.
