Mushroom-derived materials could offer benefits for developing nations in Africa

A research team from the University of Bristol has suggested that mycelium composites could offer a sustainable alternative to traditional building materials and help address socio-economic and environmental challenges in Africa.

Mycelium composites are a class of materials based on mycelium – the roots of mushrooms. These versatile materials, which have gained popularity in Europe and the US in the past decade, are produced by harnessing the ability of fungi to grow by feeding on organic biomass – eliminating the need for high-end manufacturing processes. In fact, mycelium composites can be grown almost anywhere – even at home – without the need for extensive expertise or advanced equipment.

The organic biomass used for the basis of mycelium composites are often obtained from agricultural, agro-industrial, and forestry waste streams. There is a wide range of applications for mycelium composites, including packaging materials, insulation panels, floor tiles, and furniture.

Mycelium composites are also envisioned as the ‘next-generation of self-healing and self-growing’ structures in construction. This can be achieved due to the ability of fungi to respond to light, chemicals, gases, gravity, electric fields, and mechanical cues.

Stefania’s paper suggests mycelium composites can add value to agricultural waste, potentially offering an incentive for investment in the agricultural sector and increasing productivity. Mycelium composite production could also serve as a greener waste management route not only for agricultural waste, but for plastics and other carbon-based waste materials too.

The next step for the authors is to fine-tune the properties and production of mycelium composites in order to facilitate the integration of this technology with well-established practices in diverse developing countries.
