The above drawings and experiments are a result of a study in Natural Materials and Natural Systems, an opportunity to explore material possibilities in response the current widespread use of unrenewable resources to create somewhat trivial products (i.e. plastic bags and cups). Over the course of several months, I kept a sketchbook to record and learn from my observations of the natural world. I learned to evaluate every product as a complex series of inputs and outputs that interact directly with the surrounding ecosystem. Through extensive research and experimentation, I ultimately produced a high-quality bioplastic that is both flexible and translucent, and can cure over the course of a few hours.
