Biofuels Digest recently published its "30 Hottest Companies in Renewable Chemicals and Materials" list, giving a glimpse into the wonderful world of clean tech. I didn't know much about biofuel companies and figured this list was a great place to start my research. The No. 1 and No. 5 companies, Genomatica and LS9, are both private, so I'm going to focus on the others that round out the top five.
The rankings were determined by three voting pools composed of a panel of 58 international selectors, members of the Digest online community, and subscribers to Biofuels Digest.
2. Solazyme
The subscriber portion of the Biofuels Digest poll actually ranked San Francisco-based Solazyme as No. 1. The company just went public at the end of May but is a leader in the field, counting Unilever
3. Amyris
Amyris was ranked No. 1 by the international selector pool. The company turns sugars into hydrocarbons and can produce industrial-strength lubricants, polymers, and fuel. Though it missed analyst expectations on second-quarter earnings, Amyris has inked a partnership with Total SA
4. Gevo
Gevo is based out of Englewood, Colo., a Denver suburb. The company turns corn into isobutanol, which in turn can be processed into various products like jet fuel and synthetic rubber. Similar to Amyris, Gevo also missed analysts' estimated earnings in the second quarter but is positioned for future success after signing a commercial deal with Sasol
Foolish takeaway
Lists are everywhere these days, and when they come from reputable sources like trade magazines and industry journals, they often provide a great beginning for investment research.
