Mushroom Material

Sustainable Packaging

We’ve created an eco-friendly alternative to polystyrene using mycelium and agricultural waste.

Transforming agricultural waste into eco-friendly packaging, we’ve harnessed the power of mycelium—the root structure of mushrooms—to create a sustainable alternative to polystyrene (Styrofoam)

01

Completely sustainable

Made from mycelium and agricultural waste, our product reduces landfill waste and pollution, is fully biodegradable, ensuring a minimal environmental footprint, and provides the same durability as polystyrene without the harmful effects.

02

100% biodegradable

Mushroom Material is fully home compostable, eliminating the end-of-life hassle. When you're done, simply add it to your garden, home compost, or even landfill, where it will naturally break down within months.

03

Same protective properties

Our mushroom-based material offers the same protective properties as traditional polystyrene, ensuring your items remain safe and secure during transit. With excellent shock absorption and durability, you can trust our eco-friendly alternative to deliver top-notch performance while reducing environmental impact.

How we're doing it

01

Design

We work with our clients to create sustainable packaging designs that easily replace and fit into existing processes.

02

Manufacture

Once the packaging is designed, we manufacture the finished product. We work with our clients to scale up order quantities and ship globally.

03

Supply

For clients with in-house design teams, we supply the raw material directly to their existing packaging manufacturers. The transition to our eco-friendly material is minimal.

Why we are doing it

Mushroom Material offers an affordable, scalable, and fully home-compostable alternative to expanded polystyrene. Our mycelium-based pellets are designed to be molded using the same equipment as traditional polystyrene, enabling a seamless transition. By integrating our technology into existing supply chains, we enable businesses to shift away from harmful plastics with ease and sustainability.
