Bio-based Materials is a graduate-level elective course that explores the application of bio-based materials in sustainable design practices. The course covers the principles of bio-based materials, characterization, processing, and their integration into novel design solutions. Through lectures, demonstrations, field trips, and hands-on activities, students gain a comprehensive understanding of the unique properties of bio-based materials for sustainable design practices. The course explores the challenges and opportunities of integrating bio-based materials into design practices, including considerations for material selection, fabrication techniques, lifecycle analysis, and how these materials inform our experience in space. Students engage in design projects that demonstrate the potential of bio-based materials to create innovative and sustainable design solutions. Overall, this course aims to provide students with the knowledge and skills to incorporate bio-based materials into their design practice and contribute to a more sustainable future.
