Sway Updates Seaweed Packaging Technology

J​ulia Marsh, Co-founder and CEO of Sway — the California company harnessing the power of seaweed to create home compostable replacements for plastic — keynoted the recent GreenBiz Group’s Circularity 24, a leading conference for professionals building the circular economy. In her talk she emphasized a paradigm shift away from extractive supply chains into a world where a new material future is possible, where we source clean materials from nature that can return to nature.

She noted that seaweed, shrimp shells, coffee grounds, coconut husks, microbes, pea protein, waste grasses, bamboo, and micro algae are just a few of the materials presenting viable pathways to a cleaner, biologically circular, future. The main issue at this point, is not identifying the useful materials, but scaling them.

Julia’s startup has specifically focused on scale over the past three and a half years that they’ve existed, and her team has gone through hundreds of formulations with “incredibly challenging” criteria. Just a couple months ago they unveiled their latest new age material, produced with traditional infrastructure. They call it thermoplastic seaweed, or TPSea for short. TPSea is a patented technology designed to mesh seamlessly with existing plastic manufacturing. Hear more about Sway’s progress in this video.

  • July 19, 2024: A three-year development effort, the Ethiopian Bio and Emerging Technology Institute — in collaboration with the Ministry of Innovation and Technology and the Oromia Agricultural Research Institute — has recently launched the nation’s first microalgae (spirulina) research and production center at the Adami Tulu Agriculture Center, from an investment of 8.2 million birr ($142,600 USD).

  • July 17, 2024: A study from the University of New Hampshire has found that integrating farmed shrimp with oysters and seaweed in integrated multi-trophic aquaculture (IMTA) systems significantly reduces nitrogen levels. This could make shrimp farming more responsible and potentially support the growth of the U.S. industry. READ MORE...
  • July 15, 2024: Atlantic Sea Farms, a Maine-based leader in farmed seaweed, has harvested a record-breaking 1.3 million pounds of farmed seaweed in the 2024 harvest season. The company, which partners with fishing families to farm kelp in Maine, Rhode Island, and Alaska, has expanded both the supply of domestic line-grown kelp, as well as the market for their traceable, regeneratively farmed products to American consumers, chefs, and CPG companies since 2019.

  • July 12, 2024: Researchers have created tiny, vehicle-like structures which can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming. Two types of vehicles were created: the “rotator,” which spins like a wheel, and the “scooter,” which was intended to move in a forward direction but in tests moved more surprisingly. READ MORE...
