Indian researchers produce potash from vinasse

In India, the Times of India reports that researchers at the Central Salt and Marine Chemicals Institute have developed a method to extract potash from vinasse in an effort to help reduce the toxic waste streams of sugarcane processing and ethanol production. Roughly 8-15 liters of vinasse are produced from every liter of ethanol produced, meaning the waste problem could become untenable as the country seeks to boost ethanol production for domestic blending. Producing potash for the fertilizer industry could help to add value for mills as well.
