So, we know we can make ethanol out from sugarcane, corn (ahem), sorghum, beetroots, beer, milk lactose and today we find out that latte's beloved milk companion, coffee, can be used to produce ethanol. However, instead of latte we'll speak about café con leche.
How is that? Well, a research group paid by Colombia's Federación Nacional de Cafeteros (National Coffee producers Federation, Federcafé) found that coffee grains have enough sugar content to be a source for molasses that can be fermented into ethanol. The study also affirms that coffee has a higher sugar content per bushel than corn, which makes it a clear competitor.
Federcafé's Director, Gabriel Silva, announced that the first manufacturing plants will be ready for 2008. Mr. Silva said that "coffee grains are really competitive against corn, even waste can be used as fertilizer".
Our readers already know that Brazil's President Da Silva is visiting Central America to promote the use of ethanol, even giving away the technology for free. Having an additional crop to produce it seems like another opportunity for poorer countries to have less dependence on oil.
