Wall Street Journal Names Top 10 Clean-Tech Firms

Recyclebank, a New York-based company that provides recycling-rewards programs in 29 states and the U.K., has taken the top spot on The Wall Street Journal’s second-annual ranking of venture-backed clean-tech companies.

Two solar-power firms, Suniva Inc. of Norcross, Ga., and eSolar Inc. of Burbank, Calif., came in second and third, respectively.

The Top 10 Clean-Tech rankings, announced Wednesday at the Journal's ECO:nomics Executive Conference in Santa Barbara, Calif., seeks to identify green companies with the greatest potential to succeed in an increasingly competitive sector.

A team from venture-industry tracker VentureSource calculated the rankings based on a strict set of criteria applied to 516 U.S.-based venture-backed businesses in clean technology. On March 10, the Journal plans to publish its 2011 Next Big Thing ranking of the top 50 US venture-backed companies across all industries, drawn from more than 5,700 firms. (VentureSource is owned by News Corp., which also owns Dow Jones & Co., publisher of the Wall Street Journal.)

Candidates were analyzed on the amount of capital raised in the past three years; the track records of each company's founders, managers and investors; and the percentage change in its valuation in the 12 months ended Nov. 30.

The Wall Street Journal profiles each of the winners on its website.
