The End of Styrofoam.
We don’t manufacture packaging.
We grow it — using waste streams as food for fungi.
The result: compostable biomaterials that replace Styrofoam at scale.
The Problem
Styrofoam has poisoned our supply chains for more than 70 years.
It never disappears, taking centuries to break down.
It leaches toxins into water and soil.
It pollutes oceans and destroys ecosystems.
Despite bans and regulations, it remains one of the world’s most widely used packaging materials.
Our Solution
At Upto, we’ve reimagined packaging from the ground up:
Waste In — We source agricultural, cardboard, and textile byproducts from our partners.
Fungi Transform — Mycelium, the root system of fungi, grows through this waste, binding it into strong, lightweight forms.
Packaging Out — We mold the material into protective packaging that performs like Styrofoam.
Back to Earth — After use, our packaging composts naturally within weeks.
A closed loop. No waste. No toxins. Just biology at work.
500 yrs VS 6 weeks
Packaging that disappears in weeks, not centuries.
260 tons of Styrofoam packaging eliminated each year.*
*Through only 1 of our pilots
806 tons of CO₂ emissions avoided annually.
By growing instead of manufacturing
Circular Pilots
Our pilots don’t just test packaging — they prove circularity in action. We take waste streams from our partners and transform them into mycelium-based packaging that replaces Styrofoam. When the packaging reaches its end of life, it returns safely to the earth.
agricultural waste → protective food packaging
textile waste → circular retail packaging
cardboard waste → protective foam for electronics
