The other major problem is plastic bottles. Plastic waste from PET bottles creates a massive environmental hazard, and is purely unsustainable.
What if those bottles could be used as a substrate to produce useful compounds, like vanilla flavoring? Dr. Joanna Sadler asked that exact question and using the tricks of synthetic biology installed the enzymatic steps to convert PET bottles into vanillin, the central compound of vanilla flavoring.
A genetically engineered strain of E. coli efficiently converts trash into treasure, and is a great harbinger for the future of synthetic biology in waste remediation.
