A company in California is turning greenhouse gass from methane and carbon dioxide into usable plastics, rather than using petroleum. I wonder how much GhG we could capture and convert into plastics. I don't' know what other resources are used, and therefore the total footprint of the product, but it seems to be an exciting discovery. More information on AirCarbonTM can be found here.
The kickstarter for this invention by two then 20 something Americans came from reading a newspaper article on heat-trapping methane emissions from diary farms (see USA Today article here).
