Uluu

Uluu manufactures biodegradable polymers from seaweed, producing carbon-negative and compostable polyhydroxyalkanoates (PHA) based polymer materials through microbial fermentation using seaweed, seawater, and saltwater microbes. The company offers reusable bags, biodegradable products, and injection molding grade pellets made from seaweed-based bioplastic material. Founded in 2020 and headquartered in Perth, Australia, Uluu has raised approximately $17.2M in Series A funding from investors including Main Sequence, Alberts, Mistletoe, Burda Principal Investments, and the Government of Western Australia. The company's ocean-based production model avoids competition with arable land and freshwater resources, offering a sustainable alternative to petroleum-based plastics that addresses plastic pollution while sequestering carbon through seaweed cultivation.
