Copenhagen's Natural Material Studio has pioneered an innovative design project, transforming food byproducts from the Sticks n Sushi restaurant into elegant pendant lighting. Utilizing discarded kelp from miso soup and spirulina algae, the studio has crafted unique biotextiles, demonstrating a significant step towards sustainable design practices and the creative repurposing of organic waste. This initiative not only addresses material circularity but also integrates aesthetic minimalist design with ecological responsibility.

The genesis of this project lies in the collaboration with Sticks n Sushi's Lyngby branch, a fusion Japanese-Danish eatery. Bonnie Hvillum, founder of Natural Material Studio, renowned for her innovative use of diverse waste materials, spearheaded the transformation. Her philosophy centers on the endless possibilities of repurposing biowaste, likening the process to culinary art where various components are combined to create something new and functional. The specific choice of kelp and algae was driven by their consistent availability as leftovers from the restaurant's popular miso soup and other dishes, providing a steady stream of local, underutilized resources.

The transformation process begins with the careful distillation and dehydration of large quantities of Danish kelp, typically discarded after miso soup preparation. Simultaneously, algae, often left as a wet mass from food processing, undergoes a similar treatment. These materials are then meticulously broken down: kelp into fine fibrous pieces and algae into microscopic particles. These processed biomaterials are subsequently integrated into Procel, Natural Material Studio's proprietary protein-based biopolymer. Procel, cast by hand, includes natural plant-oil softeners for flexibility and a touch of chalk for structural integrity, resulting in semi-translucent slabs.

Each lighting fixture, composed of a rectilinear frame with an LED light source, elegantly hangs from the ceiling. Hvillum artfully layers the biotextile, creating a distinct, streaky pattern that is unique to every piece. This design choice not only adds a tactile character to the restaurant's smoked oak interior but also emphasizes the material's natural origins. Beyond lighting, the studio also created 'noren,' traditional Japanese fabric room dividers, using the same innovative biotextile. This expansion into other interior elements further underscores the versatility and aesthetic potential of these upcycled materials.

The project highlights a profound commitment to circularity; the developed material is fully natural, biodegradable, and compostable, with the added benefit of being remeltable for future applications. Hvillum emphasizes the studio's interest in "locally rooted" waste streams, making seaweed an ideal choice given its abundance in Denmark. Looking ahead, the studio is keen to explore other food-based waste, such as sushi rice, continuing their mission to transform overlooked materials into tactile, atmospheric, and unexpected design elements. This endeavor not only provides a sustainable solution for restaurant waste but also enriches interior spaces with unique, environmentally conscious designs.
