Proterro is the only biofeedstock company that makes sucrose instead of extracting it from crops or deconstructing cellulosic materials.

Using CO2, sunlight and water, Proterro lowers the cost of sugar production to around $0.05/lb., unleashing the economic value of biofuels and biobased chemicals for industry partners.

The company has functioning, highly productive, patented, sucrose-producing organisms and a patent-pending, novel photobioreactor system.

A critical barrier to scale for the production of biofuels and biobased chemicals is access to reliable, economical feedstock. Proterro's unique sugar-making process removes the price volatility that comes with crop-based feedstocks and eliminates the complex and costly steps required to produce cellulosic sugars derived from biomass.

The result is an economically stable, fermentation-ready sugar feedstock for the scalable, affordable production of a variety of commercial scale fuels and chemicals through standard industrial fermentation methods.

Proterro was founded in 2008 and is backed by Battelle Ventures,Braemar Energy VenturesCultivian Ventures and Middleland Capital. The company's executive team members have expertise in building, managing, financing and scaling entrepreneurial ventures, and in taking nascent technologies to market.
