WHAT WE SAY:

TPSea Flex incorporates seaweed—an abundant marine resource that flourishes without the need for farmland, fresh water, or pesticides while supporting healthy ocean ecosystems.

After use, this film naturally decomposes in home or backyard compost, returning valuable nutrients to the soil.

DIVE DEEPER:

Ocean health is in decline due to climate change. Greenhouse gas emissions have caused ocean temperatures to warm by about 1.5° Fahrenheit, acidity to increase 30%, and oxygen levels to decrease 2%, affecting ocean productivity and biodiversity. Climate change has also led to a reduction in commercially important seafood species and could lead to a mass extinction of marine life. 
Innovative ocean farming is a climate-friendly model of aquaculture. 
Seaweed grows 30-60x faster than land-based plants, and seaweed farms can store up to 20x more carbon per acre than forests. If 9% of the world's oceans were covered in seaweed farms, they could store the annual planetary carbon budget of more than 40 gigatons a year.
Plastic packaging is the main contributor to plastic waste in our landfills and is responsible for nearly half of the global total.
Every year, 11 million metric tonnes of plastic enter our marine environments, killing marine life, destroying sensitive ocean ecosystems, and polluting food sources that support livelihoods around the world. That’s the equivalent of five grocery bags of plastic trash sitting on every foot of coastline around the world.

Key Questions to Ask:

Can you foot the bill?

Sway expects to reach a competitive price by 2027. In the meantime, the material will come at a premium. Are you able to bridge the gap in order to help scale an innovative solution?

How will you communicate end-of-life?

According to Marsh, testing revealed that many US consumers just 'don't get' composting due to a lack of availability. Can you increase circular material literacy or make connections to composting schemes?

Can you bring manufacturers on side?

Sway highlights the benefits of plastic it aims to mirror, rather than completely damning the material, which helps to smooth the transition when working with conventional plastics manufacturers. Can you take a diplomatic approach so as to convert rather than alienate people who could become part of the solution?
