Stanford scientists have discovered a novel way to make plastic from carbon dioxide (CO2) and inedible plant material, such as agricultural waste and grasses. Researchers say the new technology could provide a low-carbon alternative to plastic bottles and other items currently made from petroleum. Their goal is replacing petroleum-derived products with plastic made from CO2. Doing that without using a lot of non-renewable energy, the carbon footprint of the plastics industry could be lowered dramatically. http://phys.org/news/2016-03-scientists-renewable-plastic-carbon-dioxide.html Paper: http://www.nature.com/nature/journal/v531/n7593/full/nature17185.html
I can see the substitution of terephthalate with furfural furfural is a product from corn cabs , To deal with CO2 is something else,
