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

EUR0 379, 330 Implementing Institution MSIRI Budget 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) 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?

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

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

The initial Research Targets No more relevant Turn Key plants in India, China…. Source: www.thermaxindia.com/Fileuploader/Files/Spentwash.pdf

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

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

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

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

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 Innovative composting route for CMS Fuel route for CMS Feb – Nov 2013 Reporting Early 2014

Activities & Justification

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

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

Anaerobic: COD/BOD <90% Eff. Demineralization To extract value added products Vinasse Bio-composting Demineralization Value-added products Methanation Anaerobic: COD/BOD <90% Eff. Effluents Produce CMS that can be burnt in any normal boiler X-S CMS can follow this route CMS Effluents Gas Support Fuel Aerobic F - Irrigation D 1 Normal Boiler P TA Special Boiler Steam Electricity Carbon Credit ? Trash Fuel 3 Identify support fuel, e.g. Trash + Demineralized CMS to produce a fuel as consistent as bagasse Or as a compost 2

Vinasse Bio-composting Demineralization Value-added products Methanation CMS Gas Support Fuel Aerobic F - Irrigation D Assess technologies that atomize low calorific fuel in boilers for efficient combustion Normal Boiler P TA Special Boiler Steam Electricity Carbon Credit ? Trash Fuel 4 Saacke Atomizer

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.

Assess the VSEP membrane filtration technology for vinasse/effluents Bio-composting VSEP Demineralization Value-added products Methanation 5 CMS Gas Support Fuel Aerobic F - Irrigation D Assess the VSEP membrane filtration technology for vinasse/effluents Normal Boiler P TA Special Boiler Steam Electricity Carbon Credit ? Trash Fuel

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

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

“Roxol” Spray Dryer – Status Experimental ?

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

Local Partners contemplated OMNICANE & FUEL (Alteo) 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
