ACP Project 3.3
Technology development for
disposal of vinasse by incineration
Implementing Institution
MSIRI
Budget
EUR0 379, 330
More info on: http://www.acp-srp.eu/en
To benefit
All ACP Countries
Caribbean
Pacific
Africa
The Project
Enhance the competitiveness of
ACP sugar factories
Through sustainable disposal of
vinasse from ethanol plants
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)
 Maurice île Durable?
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.
The initial project
 By 2011 when the project was ready to start
Technology has evolved .. . . .
The initial Research Targets
1. Laboratory Scale Incinerator
Industrial Boilers exist
2. Vinasse Product Drier
Vinasse evaporators exist…..
Alcodis
3. A test Heat Recovery Equipment
Industrial CMS boilers exist …..
India, china
The initial Research Targets
No more relevant
Turn Key plants in India, China….

SAG recommendation
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
Desktop Study
Report updated in March 2012 and presented in Brussels
Scientific journals & web articles scanned - Discussions
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
Conceptual Framework
generated from the
Desktop study
Technical & economic
advantages & disadvantages
A little ….
Build Capacity
To be in a position to
recommend the best
combination of
technologies under
different situation in
ACP countries
Proposed Activities
Summary
Activities
On-site assessment of existing and promising
technologies
Period
Jan – Aug 2013
R & D activities at MSIRI
1. Demineralization & conditioning of vinasse
2. Extracting value-added products from vinasse
3. Innovative composting route for CMS
4. Fuel route for CMS

These technologies work
To treat maximum possible

This project is meant to support
these existing vinasse treatment
solutions to drastically reduce
pollution threats
