Our seaweed‑based biopolymer materials will generate significant environmental and socio‑economic benefits throughout their lifecycle


If we used 9% of our oceans to grow seaweed, we could capture 100% of our CO2 emissions

Seaweed aquaculture is so effective in reducing CO2 emissions, it beats trees, and its farming requires no land or freshwater use. Being both sustainably and ethically produced, our chemically unmodified seaweed ingredients create a harmonious relationship between communities and ecosystems. Moreover, seaweed production deacidifies and oxygenates water, enriching ocean health.


Seaweed-based packaging that extends shelf life, reduces food waste and cuts carbon emissions

Our fully biodegradable polymer packaging does the same job as single‑use plastic without adding to our acute ocean pollution crisis. Prolonging shelf life also helps solve a second urgent sustainability challenge‑food waste: today 40% of food produced is never eaten. All this, together with the fact that it requires little social or mechanical change to adopt, raises a big question: why isn’t all food sold in Searo?


From nature, back to nature: Searo material captures carbon and improves soil health when composted

Searo packaging material can be easily composted at home. The material biodegrades quickly and naturally, causing no harm to ecosystems. At this point, the carbon sequestered by seaweed and locked in our material is released back into the earth as biomass, along with other nutrients. By fertilising the soil, our packaging supports the growth of more food, and the circle is complete.
