• 10% of PX biobased by 2020… ~ 30 full-scale BioForming plants.
• Brand owner sustainability commitments provide near term market pull and support
the development of a biobased supply chain.
Coca-Cola has made 10 billion PlantBottles since launch in 2009; Odwalla is now is entirely in
100% bio PE bottles; Coca-Cola has stated its aim is to have ALL of its PET packaging based
on PlantBottle resin by 2020
• Increasing crude and naphtha prices support investment into biobased PX.

potential corn starch output
is used to make ~10% of

• The cellulosic column represents the embodied sugars of the cellulose and hemicellulose in the US DoE’s estimate of
total currently used and potential forest and agriculture biomass available in the US alone in 2012. Using 26% of that
feedstock would also supply 10% of the US gasoline market.
