Towards 80 % CO2 reduction with Deep Eutectic Solvents

  1. 1. Towards 80% CO2 reduction with Deep Eutectic Solvents 19 November 2015, European Paper Week 2015 Heiner Grussenmeyer, Stora Enso Industrial coordinator ISPT DES cluster and Provides project
  2. 2. Composed of natural products Amides Sugars Alcohols Chemical characteristics Bio degradable Non toxic Miscible with H2O DESs are a sustainable and cheap alternative to far more cumbersome solvents used today. Low vapour pressure Non volatile Low flammability DESs are used by plants to operate even during drought or frost periods. Physical characteristics (amino) acids Mimicking Nature
  3. 3. • Pure cellulose, lignin and hemicellulose • Low cost • From different sources (wood, straw)  Tailor made fibres depending on DES mixtures Dissolving lignin • Recovery of pure cellulose from papermaking residues • Low cost  Clean dissolved pulp or building block for bio chemicals, materials or fuels Dissolving cellulose Dissolving ink and other contaminants Scope
  4. 4. The dream any lignocellulosic raw material from any source with a very low energy and environmental impact Can be converted to Fibers Lignin Chemicals The DES pulp mill
  5. 5. Savings CO2 reductionEnergy reduction 40% 20% • DES replaces traditional pulping processes. • DES produces high quality cellulose, hemicellulose and sulphur-free / unchanged lignin. The true savings lie outside the mill boundaries: If lignin replaces aromatics in the chemical industry  up to – 90% overall energy and CO2 savings
