A Finnish biochemist with a passion for scuba diving is using sea algae to replace plastic used in food and cosmetic products.  The solution could stop marine suffocation in the Baltic Sea. Cyanobacteria, also called blue-green algae, can multiply rapidly and create lines on the shore that are as long as a few kilometers. The problem is caused when excessive amounts of artificial fertilizers enter the water. Its negative effects include causing oxygen deficiency, reducing water quality, and blocking out light. Mari Granström, a Finnish biochemist, has started her own company to tackle the issue. Her solution extracts toxic sea algae and sends it to different companies that can use the algae to replace petroleum, plastics, and other harmful materials in the products they manufacture. The company, named Origin By Sea, has raised over $2M in funding from both private sector investors as well as public donors such as the European Union. Origin By Sea aims to fully launch its operations by 2026. The company has reached partnerships with companies in other countries, too, including a Swedish company that aims to provide the solution to IKEA.
