Use of LCA tools in the early stages of a research project

  1. 1. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Use of LCA tools in the early stages of a research project - A case study about an innovative process for cellulose nanocrystals extraction Lille, November 2013 Olivier Talon, Séverine Coppée, Jevgenij Lazko, Tangi Sénéchal, Jean-Marie Raquez

  3. 3. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Cellulose nanocrystals extraction Process not so green High consumption of acid and water Cellulose nanocrystals :  High Young’s Modulus (= steel)  Interesting shape/aspect ratio (needle like)  Extracted from biomass (potentially from local biomass) Green nanoparticles
  4. 4. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Cellulose nanocrystals extraction Ionic Liquids are presented as green solvents of cellulose : Reuse of reagent + Recyclability + Low VOC emissions + Good solvation of lignocellulose Low amount of sulfuric acid Decrease of water consumption during purification
  5. 5. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir - Environmental cost of IL production? Currently not industrial scale product - How much recycling to improve our process? How many cycles needed for environmental benefit? How many possible to keep a good extraction? The success of nanocrystals extraction at bench will not directly provide information about the greenness of the process First bench results coupled with Simple LCA can help to pinpoint critical points Background of the study

  8. 8. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Highly simplified hypotheses Identical yields and raw materials  fibers out of system boundaries No intrinsic impact of BMIM Recycling  modeled by input division Same energetic input  not taken into account No effluent treatment  treated as emission to water Same nanocrystal quality  FU = treatment for 1 kg of CNC
  9. 9. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Data collection / choice of the method Emissions : Choice of a proxy based on toxicology literature (phenol) LCA literature negligible about IL or CNC, non existent for the combination Material inputs: firsts lab tests estimation No IL in the DB, neither as process nor as substance DB : no waste water treatment for a comparable process 1 publication about LCA of [BMIM]Cl production Calculation method: - including phenol and H2SO4 emissions - including a “water depletion” category  restricted choice: ILCD 2011 Midpoint

  15. 15. ©MateriaNova–Allrightsreservedforallcountries Cannotbedisclosed,usedorreproducedwithoutpriorwrittenspecificauthorizationofMateriaNova Le Fonds Européen de Développement Régional et la Région Wallonne investissent dans votre avenir Conclusions Necessity to refine the model: - treatment/ recycling of the acid - intrinsic impact of recycling of ionic liquid (if cycles nb increased) First results  environmental benefit is not automatic Numerous ways of improvement: - IL recycling (> 20 cycles in some publications) - “greener” production of [BMIM]Cl (or other ILs) ? (not matured production, scale effect, biosourcing…) - Yield and quality of CNC ?  FU modification ? (theoretical better thermal resistance) Scientific contribution of the project is not in balance with LCA
