 To find sustainable materials that help protect the environment while providing multifunctional utility for a variety of industries, this project explores innovative uses for Undaria pinnatifida, commonly known as wakame, an invasive seaweed species found in abundance in the San Francisco Bay Area, particularly along the shores of Ross Bay. Traditionally viewed as a threat to local marine ecosystems due to its aggressive growth and displacement of native species, Undaria pinnatifida offers untapped potential for sustainable materials development due to its unique physical properties and biomass availability. This project shifts the narrative from environmental challenge to opportunity by utilizing this invasive species as a raw material for creating biodegradable products.

After extensive research and experimentation on the physical properties of Undaria pinnatifida, a dried and ground powder form was used as the final raw material form. This basic choice laid the groundwork for exploring a variety of applications, thus creating two distinct product directions: biodegradable films and innovative "noodle" shaped objects designed for practicality and environmental friendliness.

Biodegradable films made from this seaweed powder are versatile in their application and are a promising alternative to traditional plastic films. This eco-friendly solution can be used in various industries, including packaging, where the demand for sustainable alternatives is growing rapidly. Its biodegradable nature ensures minimal environmental impact, in line with global sustainability goals.

Meanwhile, the development of 'noodle' shaped products has introduced a novel approach to product design and utility. These seaweed-based lines can be crocheted into a variety of shapes and structures, providing a unique solution for lifting and handling objects. This creative application demonstrates not only the adaptability of the material but also its potential to replace tougher, less environmentally friendly materials in specific use cases.

Through iterative formulation adjustments and creative design thinking, this project not only addresses invasive species management but also contributes to the burgeoning science of sustainable materials. By transforming Undaria pinnatifida from an ecological threat to a valuable resource, we demonstrate the potential of innovative thinking to address environmental challenges. The development of these algae-based films and 'noodles' paves the way for future research and applications in sustainable product design, providing a blueprint for a circular economy and eco-innovation.
