Sweed is a sustainable seaweed material which decomposes safely in the ocean

Is not plastic

Is not PLA

Is used as a replacement for plastic films

Is compostable and ocean-friendly

Is made out of seaweed, one of the most efficient organisms sequestering CO2, which grows without the use of fertilisers, using no fresh water and no land.  

Sustainable. Notplastic.Seaweed.

Every year, 8 million metric tons of plastics enter our ocean on top of the estimated 150 million metric tons that currently circulate our marine environments

 Sweed Challenge

Utilizing an innovative new material development, Sweed is producing a home compostable, marine-safe bio-packaging material made out of seaweed to replace current packaging solutions. 

Sweed will be 100% natural and its end of life solution is to be disposed of with food waste which will then be composted for soil health or for anaerobic digestion for energy.  

 

Unlike competing bioplastics sources, such as sugar cane or corn, seaweed farms do not require land/freshwater/pesticides/fertilisers, and they sequester carbon while reducing acidification in our oceans.

 

Why Sweed

If 9% of oceans were covered with Seaweed Farms, they would absorb enough CO2 to offset human kind carbon emissions. Seaweed is one of the most efficient organisms sequestering CO2 and it is easy to grow. Furthermore. certain species can grow up to a meter a day.

Unlike other bio-plastic materials, seaweed uses no fertilisers, no pesticides, no land, and no freshwater.

Sweed Material is ocean degradable and aims to be disposed of as home compostable. Traditional bioplastics with the level "compostable" are industrially compostable, which means they will only degrade if they are under certain conditions, such as in 60 °C environments.

Seaweed absorbs nitrogen from the oceans which also reduces ocean acidification. ​Around 20 tons of nitrogen are absorbed per square kilometre of seaweed.
