Environmental issues are becoming increasingly alarming in the current climate. The Alternative Materials studio emphasizes the use of novel materials that have not been widely used in the construction and manufacturing industries, striving to provide new opportunities to the field. The exploration begins with researching materials and techniques to identify a potential arena that may yield tangible outcomes. Next, students engage in a deeper understanding of the chosen materials to demonstrate their full potential, including organic, plant-based, recycled, recyclable, waste-generated, composite, biodegradable, circular, and low footprint. By considering environmental, social, and cultural contexts, the studio addresses sustainability in design, to reflect how we exploit resources, manufacture goods and consume products, and seek to use alternative materials. Project description: SeaMoon is an innovative lighting solution crafted from sea moss, a sustainable bio-material that addresses environmental concerns associated with harmful algal blooms. The decision to utilize algae is rooted in its accessibility and diverse species, which provide abundant resources for design. The unique properties of sea moss, particularly its ability to release sodium algal acid?€?a natural bio-bonder used in food and cosmetics?€?opened up intriguing opportunities for material experimentation. The design process began with various forms of sea moss, producing bio-concrete and bio-leather samples, but a pivotal moment arose when a spontaneous pouring of spirulina showcased a striking color gradient due to gravitational effects during drying. This inspired the integration of 4D printing concepts, emphasizing the interaction between design, environment, and time. After extensive trials, I refined the use of sea moss, overcoming challenges related to thickness, drying speed, and material detachment. Ultimately, I employed origami techniques to transform flat sheets into elegant lamp designs, merging functionality with aesthetic appeal. The final product evokes the serene ambiance of moonlit shores, making it an ideal addition to any interior space.
