This NASA-funded process transforms discarded materials into vanilla-flavored, protein-rich cookies using 3D-printing technology. The system transmutes common plastic waste and plant biomass into nutritious snacks, offering a potential method for upcycling plastic into food sources.Why it mattersThe project addresses plastic waste and food security by utilizing synthetic biology to repurpose non-biod
