Default New contender for the Biofuel of the Month award: Seashore Mallow

Via Yahoo! News: http://news.yahoo.com/s/ap/20070710/...eashore_mallow.

Quote:
Gallagher, a marine biosciences professor, says the seeds are a promising source of biodiesel, with an oil composition similar to that of soybeans and cottonseed.

Unlike soybeans and corn, which require annual plantings to feed the growing appetite for biofuels, the pink-flowered seashore mallow is both a perennial and a halophyte, or salt-tolerant plant, that grows in areas where other crops can't. With the threat of sea water encroaching on farmland and coastal aquifers because of global warming, Gallagher believes the seashore mallow could help preserve the economic value of arable land transitioning to marshland.

The meal left over after oil is extracted from mallow seeds has enough protein to be used for animal feed, while the stems have potential for use in cellulosic ethanol, Gallagher said. The roots of the plant could be used to make industrial gum.
They compared possible uses of this plant to the old saying about the usefulness of the pig: you use everything but the squeal.

I agree that it is nominally a good idea to be able to keep salt marshes (which perform several valuable ecological functions) as they are and still get substantial economic value from them. However, the thought of replacing the wide variety of plant species in marshes with a monoculture of mallow perturbs me, as we don't know what the long-term ecological impact of that would be. Granted, it would probably be less than draining the marsh and planting corn for fuel, which would disrupt what is essentially a nursery for several marine species and would require the application of large amounts of fertilizer and pesticides. However, I'm unsure whether use of mallow oil would result in a net reduction of CO2 emissions. I would be a lot more enthusiatic about this idea if I knew that a range of options for CO2-reduction were being explored in a systematic and expeditious manner, with consideration of possible side-effects of the given method on the environment.

Instead, I fear that it will turn out to be yet another ill-thought out quick fix.

Seashore mallows are OK, but marshmallows taste better.

Well, seashore mallows would be awfully salty in one's hot chocolate.

Unfortunately, there's no idea so good that it can't be applied really, really stupidly.

True, but I'd like to see a range of ideas applied, instead of relying on just one.

What, you mean you don't believe that a single, simplistic solution is a "magic bullet"?
