Relevant with Policy of Zero Liquid Discharge India (ISSCT, 2009)
ISSCT (2009) - Zero liquid discharge through spent wash incineration (R Rajesh, Thermax. Boilers, India).The policy of zero liquid discharge being implemented in India at present requires that ethanol plants adopt new technologies for effluent discharge.
By 2011 when the project was ready to start
Technology has evolved .. . . .

Scientific journals & web articles scanned - Discussions
Desktop StudyDesktop StudyConclusions
Multiple vinasse treatment technologies exist all around the world but need further optimization
Vinasse is best treated by a combination of technologies It will differ in different ACP countries
To be in a position to recommend the best
combination of technologies under

These technologies workTo treat maximum possible amount of vinasse
But not 100% pollution free…. Seasonal
This project is meant to support these existing vinasse treatment solutions to drastically reduce pollution threats
At very large scale, e.g. India Incineration is an option

2. Produce CMS that can be burnt in any normal boiler X-S CMS can follow this route
3. Identify support fuel, e.g. Trash + Demineralized CMS
to produce a fuel as consistent as bagasse
Or as a compost

• Existing distilleries – Médine, Beau Plan
• Fertilizer companies
• Other research organizations
Concluding Remarks
This project is meant to benefit all ACP countries
The MSIRI will be in a position to advise all ACP countries
• On the best combination of technologies to minimize pollution in the most economic way - Different countries, different solutions
