Taking out the Trash

Where I live, I have to pay for each bag of household waste picked up by the trash man. Each bag gets a sticker, and every so often I purchase a sheet of stickers for a not inconsiderable amount of money. Luckily, I recycle and compost, and so my actual trash output is minimal. Still, whatever volume of garbage I produce is a liability on the household balance sheet. Meanwhile, in the biobased/renewables economy, any source of unused...

Big Companies Binging on Microbes

Microbes! They are tiny but powerful. And big companies are buying in – according to a wave of announcements that began late last week. Here are some highlights from my inbox. Fuels Amyris, which has long been talking about making biofuels – particularly diesel and jet fuel – from its biobased farnesene, will embark on a joint venture with French fuel company Total. Recently Amryis had pulled back from its fuel...

Pyrolysis: the third way to biofuels

Imagine a giant pile of biomass – lets say wood chips for simplicity sake. And next to the wood chips is a big pile of money (likely from investors, whose patience for payback may vary). In a third pile is a group of job candidates: engineers, chemists & microbiologists. To get useful energy from the first pile of feedstocks requires careful consideration of all your piles. The wood chips can be burned, fermented, or –...

New Probe Aids Enzyme Mixology for Biofuels

What’s the difference between a bartender and a biofuels researcher? A bartender uses ethanol to make cocktails, while a biofuels researcher uses cocktails to make ethanol. Researchers at the Department of Energy’s Pacific Northwest National Lab have developed a probe to help create the most efficient cocktails for biofuels makers. A biofuel-making cocktail is a blend of enzymes that break down biomass (like corn stalks)....

Little Green Feedstocks

It sounds like something from a greenskeeper’s nightmare – certain folks have plans to grow algae and dandelions on purpose, and in large quantities. Firstly, in the golf course-choked state of Florida, Algenol CEO Paul Woods is scouting a location for a $500 million algae-to-fuels plant. The company was founded and has been operating in the southern part of the state for years now. Its claim to fame is cheap ethanol made...

Gates Invests In KiOR, Elevance Coming to U.S.

Bill Gates (yes, that Bill Gates), through a fund called Gates Ventures, is investing $15 million in advanced biofuels firm KiOR. Gates is not a huge cleantech investor generally (though he has backed other firms such as the young MIT spin-off Liquid Metal Battery). So it’s rather interesting that he’s decided to invest in KiOR, which is not at all an “early stage” tech firm – in fact, it is a public...
