Scottish Scientists Develop Whisky Biofuel

RabbitWho writes "It gives a whole new meaning to the phrase 'one for the road.' Whisky, the spirit that powers the Scottish economy, is being used to develop a new biofuel which could be available at petrol pumps in a few years. This biofuel can be produced from two main by-products of the whisky distilling process – 'pot ale,' the liquid from the copper stills, and 'draff,' the spent grains. Copious quantities of both waste products are produced by the £4bn whisky industry each year, and the scientists say there is real potential for the biofuel, to be available at local garage forecourts alongside traditional fuels. It can be used in conventional cars without adapting their engines. The team also said it could be used to fuel planes and as the basis for chemicals such as acetone, an important solvent."

      I used to work at Glenturret Distillery and pretty much all of the by products were recycled or used in some way. Even the casks were ex-bourbon or ex-Sherry casks. The draff (remainder of the 'mash' process) was picked up by a local farmer twice a day and fed to his cattle (cue corny joke for the tourists about pissed cattle). Very rich in energy apparently.

      Distilleries in the past had had explosions from the from the spirit dense air in the still rooms - I can see why the pot ale (which is actually quite a lot of liquid that is left in the still) is useful for butanol. The spirit safe - a locked glass cupboard in the still room had a mechanical chute to "cut" the spirit run - from a wash still (the first distillation) only about 40% of the total volume was taken for the 2nd spirit still. The article didn't say whether the butanol was made from the wash still pot ale or the spirit still. This has quite significant volume ramifications. A wash still based product would have much larger potential volumes than a spirit still product. Often, a wash still is twice the size of a spirit still. On a slow day we used to make molotov cocktails from spirit and got up to all sorts of high jinks.

      Hopefully this will provide much needed jobs in rural Scotland.

    Scottish Scientists Develop Whisky byproduct Biofuel, is what the headline should read. The current one announces a ridiculous insanity involving using one even more scarce resource when the actual significance is that they've created a use out of a waste product. This is better than something from nothing, since the waste product was itself a problem (though I understand some distilleries were already converting it into fuel to power the plant).

    p.s. I never understood the draw to whisky when I'd tried and found "meh" even the supposed coveted bottles that are semi-widely available until I was signed into the Whisky Society in Edinburgh one night. Sure selling whisky by number without identifying the source is probably another marketing tactic but this was one of those rare "wow" moments where all the hype and marketing hyperbole actually seemed understated.

    There are a lot more cars consuming more fuel than the whisky industry will be able to service.

    Even a couple percentage delta in demand for fuel might impact the price dramatically due to inelastic demand: "That is, a 10% hike in the price of gasoline lowers quantity demanded by 2.6%. In the long-run (defined as longer than 1 year), the price elasticity of demand is -0.58; a 10% hike in gasoline causes quantity demanded to decline by 5.8% in the long run." I suppose whether the reverse is true - a 5.8% decrease in demand is necessary to decrease prices by 10% in the long run - depends on how efficient you believe the market for gasoline to be. But there's no good reason to believe decreasing demand by 1% would equal only 1% reduction in price.

    This can be done with the Budweiser by products too. The first step in making Whiskey is to make beer. Then you distill the beer, and age the grain alcohol to get whiskey. "pot ale" is the beer left over after distillation. "draff" is the spent grains, used to make the beer. So Budweiser has tons (many thousands) of draff, but no pot ale.

    It was implied by the article that the spent grain, draff as it is called, is going to waste. I would really hope that is a mistake in the article.

    Spent grain is very nutritious for livestock and unsurprisingly they love it, especially pigs. It's only the alcohol the distillers are interested in, but the farmers and their pigs are interested in the extra nutrients converted by the yeast that remain in the draff. There are also many old, traditional recipes for making bread from spent grain. I know a few that actually brew small beer just to have a supply of spent grain for these recipes.

    These "byproducts" are very valuable economically even they might not have a high direct resale value. It's not too unlike metal shops and the filings swept up at the end of the day. I read about a fellow that had arranged to sweep shop floors at the end of each shift for free. After a few years, he had a small team of employees and was covering many shops in the region and turning a good profit. That was before the metal shortage. Once converted to meat or bread they have high value.
