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 from cyanobacteria in a custom-designed bioreactor. Woods does not, as far as I know, have plans to re-purpose stagnant water traps for the purpose of growing his feedstock.
But Florida, though it is sunny and warm, might have missed out on this slimy opportunity. In recent months, Woods questioned the state’s commitment to biofuels. For example, Governor Rick Scott repealed a state law requiring 10% ethanol in gasoline. But now, according to Fort Myers ABC 7 News, the company has been persuaded to build in its home state – apparently the estimated 1,000 jobs was just the ticket to getting a warmer welcome. Algenol needs to be sited near a major CO2 source (i.e., factory or power plant emissions) and says potential partners have come forward.
Meanwhile, it’s called the Russian Dandelion, though it grows in Germany. This common lawn scourge is bringing about not curses, but praise, for its rubber producing capability. Tire makers are enthused about its white latex sap. The goo is expected to give the subtropical rubber tree a bit of competition. Making rubber from dandelions is not a new idea, but has been given new life by a project at the Fraunhofer Institute for Molecular Biology and Applied Ecology.
Fraunhofer scientists, in a collaboration with folks from tire firm Continental are working on a production process for making tires from the dandelions. In addition to the manufacturing process, the researchers are also using DNA markers to grow new varieties of the plant with higher rubber yields.
The project sounds kind of cute but the researchers behind it are dead serious. The partners have already begun a pilot project and plans are afoot to move to industrial scale. According to them, the first prototype tires made from dandelion rubber will be tested on public roads over the next few years.
