The solids, which consist largely of lignin, are recovered from the stillage with a centrifuge, and can then be burned to generate steam for the overall process.
The cask sits on top of the bar on a wooden rack known as a stillage.
Here, the ethanol is separated from thesolids known as “stillage.”
In Brazil stillage, a nutrient rich remainder of sugar cane fermentation, is returned to sugar cane plantations.
Initially, on the introduction of the Proalcool program in Brazil, pollution of waterways increased in several cases because of the discharge of stillage from distilleries directly into the waterways.
This is no longer a problem, as the stillage is now being used as fertilizer or being treated before discharge (World Bank data).
By-products include stillage for fertilizer, electricity from bagasse in the case of sugarcane, and carbon dioxide and animal feeds from corn.
For sugarcane, the stillage from fermentation is used as a fertilizer on the plantation, and bagasse residues are used for cogeneration purposes, with surplus electricity being sold to the grid (Goldemberg, Monaco, and Macedo 1993).
In Brazil and Zimbabwe stillage is increasingly being used as a substitute for chemical fertilizers in sugarcane fields: through the use of stillage in Sao Paulo (Brazil), productivity increased by 20-30 per cent
Stillage and other wastes from ethanol plants can cause serious damage to aquatic ecosystems if they are mishandled; the high BOD and COD levels in the stillage could result in oxygen depletion in any waters receiving the waste.
