Notpla

What Happened

Notpla makes plastic-free packaging (films, coatings, sachets) from seaweed and plants, best known for its edible "Ooho" water capsules and its plastic-free sauce sachets used at the London Marathon. Its Series A+ is fueling a major US expansion.

Why It Matters

Edible water capsules generate headlines, but the plastic-free sauce sachets at scale events like the London Marathon are the more commercially meaningful proof point — thousands of single-use sachets is a real stress test most packaging startups never reach.

Proven at marathon scale — thousands of single-use sachets, zero plastic.

FET's Takeaway

Seaweed as a feedstock has real advantages over land-based bio-plastics — no freshwater irrigation, no competition with food crops for arable land — which matters as this category faces the same land-use scrutiny that hit early biofuels.
