From Colorado, news has arrived that Gevo is now selling paraxyleme to Toray, one of the world’s leading producers of fibers, plastics, films, and chemicals. It’s producing PX from isobutanol, one of its three molecules in production (the others are jet fuel and iso-ocrane) at its complex in Silsbee, Texas. Toray expects to produce fibers, yarns, and films from Gevo’s PX.
Seeing high customer demand for more eco-friendly product packaging, Coca-Cola introduced the first-generation Plant Bottle in 2009, with up to 30 percent renewable content. The company has now distributed more than 10 billion first-generation PlantBottle packages in 20 countries worldwide, and is bullish on reaction from customers.
Why the limit at 30% renewable content? That’s where PX comes in. It’s PET is produced from renewable MEG (ethylene glycol) and PTA (purifiedterephthalic acid). PTA in turn is produced from paraxylene (PX), which until now has not been available from renewable sources on a commercial basis. READ MORE
