About
Grown.bio is a Netherlands-based sustainable packaging company that grows custom protective packaging using mycelium — the root structure of mushrooms — combined with locally sourced agricultural waste fibers. The manufacturing process takes just 7 days: a mould is filled with a mycelium-substrate mix, allowed to grow in a controlled environment for 5 days as the mycelium feeds on organic waste and binds the material, then dried for 2 days to stop growth. The result is lightweight, durable packaging suitable for light to very heavy items, fully replacing EPS (Styrofoam) foam without environmental harm. Grown.bio offers several product lines including Industrial Packaging, Luxury Packaging, Insulating Packaging, and ONE4 Packaging. They also provide a 'Grow It Yourself' kit for businesses wanting to produce mycelium packaging on-site, as well as mycelium-based interior design products. All packaging is certified 100% compostable at home and in marine environments, making it a genuinely circular solution that reduces plastic pollution and CO₂ emissions. The company is ideal for brands, manufacturers, and retailers looking to replace single-use plastic or EPS packaging with a sustainable, premium alternative. With an active investment opportunity and a growing product portfolio, Grown.bio is positioned at the forefront of the bio-based materials industry.

- Comparable Performance to EPS: Offers excellent lightweight protection matching EPS foam, making the switch seamless for manufacturers.
- Versatile Applications: Suitable for industrial, luxury, and insulating use cases, with custom shapes available for virtually any product.
Cons
- Higher Unit Cost Than EPS: Bio-based manufacturing processes can result in higher per-unit pricing compared to mass-produced EPS or plastic.
- Limited to Physical Products: Grown.bio serves packaging needs only — it is not a software or digital platform, limiting its scalability for purely digital businesses.
- Production Lead Time: The 7-day growing cycle requires planning ahead, which may not suit businesses needing immediate on-demand packaging.
