In South Korea, where the ancient practice of kimchi-making generates mountains of discarded radish each year, scientists have found a way to close the circle — engineering bacteria to transform that forgotten waste into plastic that the earth can reclaim. A team at the World Institute of Kimchi combined computational metabolic modeling with genetic engineering to coax E. coli into converting radish by-products into biodegradable polymer with remarkable efficiency. The work is less about kimchi than it is about a broader human reckoning: that what we call waste is often only a resource we have
