1 Mid-Term Review 2 October 2012 MSIRI Réduit Mauritius

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

3 EUR0 379, 330 Budget Implementing Institution MSIRI More info on:

4 To benefit Africa Pacific Caribbean All ACP Countries

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

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

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

8 Design 1.Laboratory Scale Incinerator Industrial Boilers exist 2.Vinasse Product Drier Vinasse evaporators exist….. Alcodis Construct 3.A test Heat Recovery Equipment Industrial CMS boilers exist ….. India, china The initial Research Targets

9 No more relevant Turn Key plants in India, China…. Source:

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

11 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 To be in a position to recommend the best combination of technologies under different situation in ACP countries Conceptual Framework generated from the Desktop study Build Capacity Technical & economic advantages & disadvantages A little …. Technical & economic advantages & disadvantages A little ….

14 Proposed Activities Activities Period On-site assessment of existing and promising technologies 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 Feb – Nov 2013 Reporting Early 2014 Summary

15 Activities & Justification

16 Vinasse Bio-composting Gas Support Fuel TA Special Boiler Steam Electricity Carbon Credit ? Methanation Anaerobic: COD/BOD <90% Eff. 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 Aerobic F - Irrigation D Effluents CMS Effluents Investigate what ? Demineralization Value-added products Partial P

17 Demineralization Bonnet et al., (2002) Value-added products & depotassified vinasse

18 Vinasse Bio-composting Gas Support Fuel Demineralization Value-added products TA Special Boiler Steam Electricity Carbon Credit ? Normal Boiler Normal Boiler Trash Fuel Methanation Anaerobic: COD/BOD <90% Eff. Demineralization 1.To extract value added products Aerobic F - Irrigation D Effluents CMS Effluents 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 P

19 Vinasse Bio-composting Saacke Atomizer Aerobic F - Irrigation D Gas Support Fuel CMS Demineralization Value-added products TA Special Boiler Steam Electricity Carbon Credit ? Normal Boiler Normal Boiler Trash Fuel Methanation Assess technologies that atomize low calorific fuel in boilers for efficient combustion P

20 Atomizer for Vinasse – Status Experimental Two case studies were presented for factories incinerating vinasse-like material (soy molasses) at Araucaria and Cambé, both in the Parana state of Brazil.

21 Vinasse Bio-composting Aerobic F - Irrigation D Gas Support Fuel CMS Demineralization Value-added products TA Special Boiler Steam Electricity Carbon Credit ? Normal Boiler Normal Boiler Trash Fuel VSEP Methanation Assess the VSEP membrane filtration technology for vinasse/effluents P

22 VSEP – Status Experimental Vibrating Membrane Technology - Pilot scale testing completed in Brazil in 2010 Vinasse Concentrate

23 Vinasse Bio-composting Aerobic F - Irrigation D Gas Support Fuel CMS Demineralization Value-added products TA Special Boiler Steam Electricity Carbon Credit ? Normal Boiler Normal Boiler Trash Fuel or Compost VSEP Spray Dry Fertilizer Ash Methanation 5.To investigate the impact of VSEP filtration on steam demand in evaporator station 6.To investigate whether products from VSEP filtration or CMS can be spray dried ….. Storable solid fertilizer P

24 Roxol Spray Dryer – Status Experimental ?

25 CMS Characterization Demineralization Conditioning Vinasse Boiler Trash Fuel Compost VSEP Spray Dry MSIRI labs On-site Activities On-site On-site or MSIRI labs MSIRI labs Atomizer

26 VinasseBio-composting Aerobic Fert - Irrigation D CMS Methanation This ACP project is meant to support typical vinasse treatment system P

27 Local Partners contemplated OMNICANE & FUEL (Alteo) Existing distilleries – Médine, Beau Plan Fertilizer companies Other research organizations

28 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
