The research examines the potential of fungi-derived leather as a sustainable alternative to traditional and synthetic leathers. Bovine leather, while having benefits such as renewability and biodegradability, poses environmental issues like emissions from cattle farming and concerns regarding animal welfare. Synthetic leather, made from plastics like polyurethane, is not biodegradable and derives from non-renewable fossil fuels, leading to environmental challenges.
Fungi-derived leather substitutes, mainly from mycelium, offer a renewable, biodegradable, and animal-free alternative. The process of turning fungal mycelium into leather substitutes involves pre-treatment, chemical and physical treatment, and post-treatment to enhance the material for various applications. This includes hydration, crosslinking, compression, and dyeing to achieve the desired aesthetics and mechanical properties similar to animal leather.
The environmental impact of fungal leather is considerably lower compared to bovine and synthetic options, aligning with sustainability goals. Fungal materials also present a circular economy approach, as they can be composted at the end of their life cycle, minimizing waste generation. The commercial and research interest in fungal materials is increasing, as seen in their applications ranging from clothing fabrics to leather substitutes.
Fungal species like Agaricus bisporus (Button Mushroom) and Ganoderma lucidum (Reishi) are among the varieties being explored for leather-like materials due to their fibrous networks and growth characteristics. The production methods, including solid-state and liquid-state surface fermentation, are under research to refine the process for mass production and commercial use.
In conclusion, fungi-derived materials offer a promising solution for eco-friendly leather substitutes, contributing to a reduction in environmental impact and advancing material science in the pursuit of sustainable alternatives to traditional materials.
