I participated in a workgroup focused on biomaterials during the Interactivos 2019 Residency at Silo - Art and Rural Latitude, Serrinha do Alambari, Rio de Janeiro, Brazil. We aimed to experiment with digital manufacturing tools to create novel natural materials using organic resources. Furthermore, we also developed natural pigments with regional fruits and plants. For our experimentations, we had at our disposal thermoforming machines, 3D printers, laser cutter machines, as well as sticks, rocks, leaves, and the inspirational sounds of the Mata Atlântica nearby forest, among others. We wanted to generate biodegradable materials and evaluate their application in regenerative products that could not only reduce but also revert environmental impact. We have also explored mycelial and kombucha-made biomaterials and the production of educational zines teaching how to reproduce our experimental protocols. We then delivered them to teachers and young students from regional schools during a fair we promoted, and the digitalized materials are also openly available online. After the Residency, I experimented with mycelium proliferation during the First Open Technologies Latin American Residency, in 2019, which took place at CTA, UFRGS. We tested cloning and growing mycelium derived from mushrooms bought in the supermarket on wood scraps, with low-cost incubators made of boxes and an aquarium heater. I also investigated kombucha leather forms and colors, at my home, using different types of drying methods and natural teas.
