Passive cold-chain shipping boxes made from chemically-treated palm leaf fiber with phase-change material capsules. Built for off-grid tropical regions.
Get StartedA health worker in a remote Philippine village opens a palm leaf box after 5 days in 35C heat with no ice left. The digital temperature display still shows 4C the vaccines are perfectly viable.
The treated palm fronds combined with salt hydrate PCM capsules created a thermal barrier that outperformed commercial foam coolers.
Chemically-treated palm fronds create superior insulation, 40% cheaper than styrofoam and completely biodegradable.
Salt hydrate phase-change material capsules maintain stable temperatures for days without external power.
Dome-shaped architecture maximizes thermal efficiency with minimal surface area exposed to heat.
40% cheaper than foam alternatives. Recurring revenue from replacement PCM capsules at $15 every 6 months.
Targeting health ministries and NGOs. Pilot with 3 countries, 50,000 units in year one.
Palm leaf sourcing creates local jobs at $3 per kg harvested, supporting rural economies.
