Dear MEL Topic Readers,
Whisky generates a lot of waste. It could soon help fuel your car
Biofuels, such as renewable electricity, biogas, or liquid biofuels, account for just 3% of the fuel used in global transport. They are mainly made from corn, soya beans, or sugarcane, and are regarded as a low-carbon substitute for fossil fuels. While their environmental benefits are well recognized, it still takes a substantial amount of land to produce. This could give significant impacts on biodiversity, carbon storage, and food security. For example, corn is produced to feed humans and pigs as well as to produce biofuel. To harvest more corn to produce more biofuel, you’ll need more land or sell more to biofuel producers, which could destroy more forests or sacrifice the food supply. But what if the waste to produce some other product is used for biofuels? A biofuel scientist came up with an idea to convert the waste to produce whisky into biofuel. Surprisingly, a substantial amount of waste and by-products are created to distill whiskies, such as draff, pot ale, and lees. It seems like a good attempt to use the waste to produce something that many people crave. Will that biofuel make the car drunk or alcoholic?
Enjoy reading the article and learning about how whisky waste could be turned into biofuel.
