This project explores alginate a biodegradable material derived from seaweed, dyed with it's natural pigments. Through experimenting with texture, colour, and form, we crafted a fashion piece echoing seaweed’s movement. After use, it dissolves in water, closing the loop. Our documented process encourages sustainable design and material innovation beyond conventional plastics.

MATERIAL TINKERING
Through hands-on material tinkering, we explored bioplastics by experimenting with recipes using ingredients like corn starch, gelatin, agar-agar, and alginate.
Each blend revealed different material properties. To add colour and texture, we used natural sources such as pomegranate, orange, strawberry, avocado, red onion peel, and eggshells.
alginate experiments
We explored texture and color in alginate by using seaweed collected from Denmark and Ireland. Through natural dyeing and material experiments, we created a series of biodegradable bioplastic samples using sodium alginate valued for its flexibility, film-forming, and non-toxic properties.
Moulding techniques
We explored how to mold alginate bioplastic using techniques like two-part, single-sided, and compression molding. Molds were created using 3D printing, laser cutting, and repurposed objects. Experiments focused on shaping the material with curves, textures, perforations, and organic forms to test its versatility and reduce shrinkage.
User testing
What would the material say
I am a new, innovative material.
An alternative to plastic and synthetic fabrics.
My form is organic and flowing, echoing the movement of my home: the sea.
Like the tides, I drift away when my purpose is fulfilled, returning gently to where I came from.
I dissolve harmlessly, becoming one with the ocean once more.
