Intermediates Start-ups Star in Green Chemistry
Genomatica and BioAmber have been named as two winners of the Presidential Green Chemistry Challenge Awards. This is a good week for the renewable intermediate chemicals industry. (You can see the full list of awardees here.)
Start-ups have been moving on to the winners podium beginning in 2009 with Virent, a catalyst-focused bio-fuels firm. Green chemicals and fuels firm LS9 popped onto the list in 2010. But having two tech start-ups in 2011 suggests that these new companies are taking on a larger share of the attention paid to green chemistry by policy makers.
Historically, winners of the Challenge Award have been larger concerns like Proctor & Gamble, Eastman Chemical, Dow Chemical, and Cargill. In contrast to those diversified companies, renewables start-ups must see their green chemistry succeed in the market or they will go out of business.
Knowing this, C&EN tracks with interest statements from start-ups about plans for scaled-up facilities, strong corporate partnerships, and estimates of cost-competitiveness with petroleum-derived chemicals. It can't be all about the technology. Likewise, the discussion about the award to Genomatica on the EPA's website encompasses the technology itself, the many environmental benefits, and the possible low-cost manufacture of the company's bio-BDO. I'll peel off just the green bennies from the discussion in this quote from the award:
"Initial lifecycle analyses show that Genomatica's Bio-BDO will require about 60 percent less energy than acetylene-based BDO. Also, the biobased BDO pathway consumes carbon dioxide (CO2), resulting in a reduction of 70 percent in CO2 emissions. Fermentation requires no organic solvent, and the water used is recycled. Furthermore, the Bio-BDO fermentation process operates near ambient pressure and temperature, thus providing a safer working environment."
For BioAmber, a company in the midst of scale-up plans for bio-based succinic acid, the award focuses on how the firm's product can enter the marketplace. "BioAmber's economic advantage has given a number of chemical markets the confidence both to use succinic acid as a substitute for existing petrochemicals and to develop new applications for succinic acid. Succinic acid can replace some chemicals directly, including adipic acid for polyurethane applications and highly corrosive acetate salts for deicing applications. BioAmber has also made it economically feasible to (1) transform biobased succinic acid into renewable 1,4 butanediol and other four-carbon chemicals; (2) produce succinate esters for use as nontoxic solvents and substitutes for phthalate-based plasticizers in PVC (poly(vinyl chloride)) and other polymers; and (3) produce biodegradable, renewable performance plastics."
