ULUU is a technology company based in Perth, Australia, that develops biodegradable materials derived from seaweed to replace conventional plastics. Their product is a natural polymer called polyhydroxyalkanoates (PHAs), created by fermenting sugars extracted from seaweed. These materials perform like traditional plastics but are fully biodegradable, compostable, and marine-safe, targeting industries such as packaging, fashion, furniture, and automotive manufacturing. ULUU’s technology addresses the environmental crisis of plastic pollution by reducing reliance on fossil fuels, sequestering carbon, and minimizing marine waste, while also empowering coastal communities through sustainable seaweed farming. The company has demonstrated strong growth momentum, recently raising AU$16 million in Series A funding to scale from a pilot plant to a demonstration facility capable of producing commercial volumes[1][2][3][5].
ULUU was founded in 2021 by Dr. Julia Reisser, an ecologist and ocean plastics researcher, and Michael Kingsbury, a former business executive and M&A lawyer. Julia’s background includes early involvement with The Ocean Cleanup and a PhD focused on ocean plastics, which inspired her to seek solutions targeting the root cause of plastic pollution rather than just cleanup. The idea for ULUU emerged from the lack of viable renewable alternatives to fossil-fuel-based plastics. Together, Julia and Michael transformed this vision into a business, developing and patenting the seaweed-to-PHA technology in Western Australia. Early traction included operating a pilot plant and securing initial funding, which validated their approach and set the stage for scaling production[3][4].
ULUU rides the global trend toward sustainable materials and circular economy solutions amid growing regulatory and consumer pressure to reduce plastic pollution and carbon emissions. The timing is critical as industries seek alternatives that do not compromise performance or require new manufacturing infrastructure. ULUU’s approach aligns with increasing investments in bio-based materials and ocean health restoration, positioning it as a pioneer in marine-derived bioplastics. By enabling manufacturers to replace fossil plastics with seaweed-based alternatives, ULUU influences the broader ecosystem by promoting regenerative ocean farming, reducing environmental impact, and fostering new sustainable supply chains[1][2][3][5].
ULUU is poised to transition from pilot to commercial scale with its new demonstration plant, aiming to produce tens of tonnes annually and eventually thousands of tonnes to serve global markets. Future growth will be shaped by trends in sustainability mandates, corporate commitments to net-zero, and consumer demand for eco-friendly products. The company’s collaborative approach with seaweed farmers, manufacturers, and governments will be key to scaling impact. As ULUU advances, it may become a global category leader in biodegradable bioplastics, significantly influencing how materials are produced and consumed worldwide, while contributing to ocean health and climate goals[2][3][5].
ULUU has raised $16.0M across 2 funding rounds. Most recently, it raised $11.0M Series A in October 2025.
