2. Technology development for disposal of vinasse by incineration
ACP Project 3.3
Technology development for disposal of vinasse by incineration

3. EUR0 379, 330 Implementing Institution MSIRI Budget

4. To benefit
All ACP Countries
Caribbean
Pacific
Africa

5. The Project Enhance the competitiveness of ACP sugar factories
Through sustainable disposal of vinasse from ethanol plants

6. The initial project Initiated in 2005
Vinasse incineration can provide a satisfactory solution to the pollution problem
…... still holds
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.
ENCORAGED IN INDIA
Maurice île Durable?

7. The initial project By 2011 when the project was ready to start
Technology has evolved

8. The initial Research Targets
Design
Laboratory Scale Incinerator Industrial Boilers exist
Vinasse Product Drier Vinasse evaporators exist….. Alcodis
Construct
A test Heat Recovery Equipment
Industrial CMS boilers exist ….. India, china

9. The initial Research Targets
No more relevant
Turn Key plants in India, China….

10. SAG recommendation In the light of technological evolution …..
April 2011
In the light of technological evolution …..
A comprehensive “Desktop Study” to be carried out to re-assess the R&D strategy on vinasse treatment

11. Report updated in March 2012 and presented in Brussels
Desktop Study
Report updated in March 2012 and presented in Brussels
Scientific journals & web articles scanned - Discussions

12. Desktop Study
Conclusions
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

13. Build Capacity Conceptual Framework generated from the Desktop study
Technical & economic advantages & disadvantages
A little ….
THE SCHEMATIC DIAGRAM SHOWS THE Conceptual Framework FOR VINASSE treatment gen=rated from the desktop study
EACH ONE OF THESE TECHNOLOGIES have technical & Economic advantages and disadvantages
A LITTLE KNOWLEDE IS DANGEROUS, HENCE IT IS VERY IMPORTANT TO UNDERSTAND ALL THESE TECHNOLOGIES AND MASTER A FEW, BEFORE WE CAN MAKE RECOMMENDATIONS…..
THIS REORIENTED PROJECT WILL ALLOW US TO Build capacity
Build Capacity
To be in a position to recommend the best combination of technologies under different situation in ACP countries

14. Proposed Activities Activities Summary Period
On-site assessment of existing and promising technologies
Jan – Aug 2013
R & D activities at MSIRI
Demineralization & conditioning of vinasse
Extracting value-added products from vinasse

These technologies work
To 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
