Why not just bury the stuff? That's a ton of carbon that isn't going into the atmosphere. They are kind of going the wrong way. If you depolymerize the junk it's going to degrade to CO2 eventually. In fact, plastics are an excellent carbon sink if we ever need a durable method of sequestering carbon. Plastics wouldn't be nearly as terrible if we weren't making them from oil. Sequestering atmospheric CO2 and polymerizing it using enzymes would mean that we are taking it out of the atmosphere and putting it back in the ground where it belongs.
