Green Pre-Selection 2026

Winner in category Packaging

Sealeo's seaweed-based thermal packaging replaces petrochemical foams and gels for pharmaceutical transport. This integrated system of biofoam and hydrogel coolant delivers superior passive cooling (up to 2.5x longer) and is made entirely from rapidly renewable marine biomass, avoiding land use and persistent plastic waste. The materials are fully compostable, supporting a transition to circular supply chains.

Sealeo redefines pharma logistics by merging seaweed biofoam and hydrogel into a unified thermal system. With 2.5x the duration of petrochemical plastics and a complete "sea-to-soil" loop, it is a masterclass in high-performance circular innovation.
