Packaging and product materials remain heavily dependent on petroleum-based plastics and foams that persist in the environment long after their useful life. Expanded polystyrene and other synthetic materials are widely used because they are lightweight, durable, and inexpensive, yet they are difficult to recycle and contribute significantly to global plastic pollution. As companies seek alternatives that align with circular economy principles, bio-based materials are gaining increasing attention. Biomyc, a sustainable design and innovation company based in Sofia, Bulgaria, develops products and packaging made from mycelium composites for premium brands. Mycelium, the root-like structure of fungi, can bind agricultural by-products such as hemp, straw, husks, or plant fibers into lightweight composite materials. These materials can be grown into specific shapes within a few days, forming durable structures suitable for protective packaging, automotive components, construction materials and products. By combining biotechnology, eco-design, and renewable feedstocks, Biomyc aims to replace conventional plastic foams with biodegradable materials that can safely return to the environment after use.

Technology and Product

Biomyc works with mycelium composites, a biomaterial created by growing fungal mycelium through agricultural residues such as hemp, straw, or husks. During growth, the fungal network binds the particles together, forming a lightweight yet rigid structure that can be molded into specific shapes. After growth, the material is dried to stop biological activity and stabilise the composite. The resulting products offer cushioning and structural properties comparable to foam-based packaging or construction materials. Biomyc focuses on product and packaging design using these composites, developing solutions for brands seeking biodegradable alternatives to conventional protective packaging. The company reports collaborations with brands including Mercedes-Benz, KIA, and BAT across multiple sectors.

Industrial Fit and Applications

Sustainable packaging and materials have become a priority for industries seeking to reduce plastic waste and environmental impact, including FMCG, automotive, and construction. Mycelium composites offer a renewable alternative to petroleum-based foams commonly used for protective packaging and selected components. Biomyc develops packaging inserts, product housings, and design objects that can replace expanded polystyrene and similar materials. The solutions are particularly relevant for electronics, cosmetics, wine and spirits, and luxury consumer goods, where both protection and visual design are important.
