Inviting scalable solutions, inspired by nature, that enable California’s plastic transition.

The global plastics crisis is at a breaking point.

California’s SB 54 has created a deadline for action in the 4th largest economy in the world.

The hard truth: too much of what we make, use, and discard ends up where it doesn’t belong, and never truly goes away.

But biology offers a different ending to that story.
