Gasification and elephant poop: funny words will save us all
Gasification might sound like something your uncle goes through after too much dairy, but it’s actually an old biofuel technology that scientists are reexamining in the wake of the current fuel crisis. According to a Science Daily press release, gasification “is a process that turns carbon-based feedstocks under high temperature and pressure in an oxygen-controlled atmosphere into synthesis gas, or syngas.” Before the advent of the electric light bulb, gas was squeezed out of coal (and used to power gas fixtures) by gasification, and it was briefly considered as an ethanol extraction process back in the 70s. But the stakes might be even higher today, and there’s an ethanol mandate to meet, which means that whatever extraction/distillation methods we use need to be as streamlined and efficient as possible.
Turning the syngas into ethanol might be a key - Ames Lab chemist and Chemical and Biological Science Program Director Victor Lin was quick to point out its merits to Science Daily. “It expands the kinds of materials that can be converted into fuels,” Lin said, adding that such materials include “the waste product from the distilling process or any number of other sources of biomass, such as switchgrass or wood pulp.” In fact, pretty much any carbon-based material can be converted into syngas. And where there’s syngas, ethanol’s not far behind.
But wait! There’s more good news from Science Daily; “The work of Delft researcher Marko Kuyper…has greatly improved the conversion of certain sugars from agricultural waste to ethanol.”
The long and short of it is that Kuyper added a gene found in elephant poop to the baker’s yeast that combines with sugar to make ethanol. This gene can break down the sugars in the materials left over from a batch of ethanol, which can in turn be processed into more ethanol. This is a big step, and Kuyper deservedly received a Ph.D for his efforts thus far. Expanding his work to the industrial level will help the bio-ethanol process tremendously, and we here at Corn Car officially salute his efforts by presenting him with The Corn Car Suggestive Teddy Bear Award for Scientific Innovation.
