Workshop 2.1 Green Chemistry, change of Raw
material and Resources
M. Dahanayake, H. Strub

• The session was overly subscribed about 30
  papers submitted for publication reflecting the
  importance in the trends for Green and
  Sustainable chemistry covering a broad range of
  industrial applications.
• It was evident from the papers that appreciation
  for green chemistry is growing fast and is
  certain to capture major shares in the industrial
  and personal care markets within the coming
  decade.
• Among the papers three key themes were reflected
• Raw materials from natural resources sugar
  starches, replacing raw materials based on fossil
  carbon.
• Environmentally friendly, biodegradable, non
  flammable solvents to replace products, HAPs and
  flammable, toxic or halogenated solvents.
• Greater emphasize on environmentally safe,
  biodegradable, green emulsifiers for waterborne
  formulations.

Workshop 2.1 Green Chemistry, change of Raw
material and Resources

• CONCLUSIONS
• Raw materials described ranged from vegetable
  oils, Sugars and Carbohydrates
• The raw materials described are freely available.
  However demonstrating the scale up in industrial
  scale to meet the cost performance targets
  against the synthetics, remain a challenge
• APPLICATIONS
• In the field of detergents, house hold cleaners,
  personal care and paints, the public demand for
  sustainable green products should be emphasized.
  There are much more goings on in these industries
  than the papers were suggesting.
• Bitumen application (green surfactant and flux
  oils) were well represented as shown by the
  number of papers submitted
• Unavoidable gtgt new challenges both at the
  scientific and industrial level

Workshop 2.2 Heavy oil Enhanced Oil Recovery
C. Dalmazzone, L. Marquez

• CONTEXT
• average recovery rate 33 gtgt EOR
• non conventional oil, heavy oils...
• WORKSHOP
• 7 papers, mostly on heavy oils and rupture of
  water in crude oil emulsion
• combination of physical means (wash tank,
  magnetic or electric field) with chemical
  formulations
• developing interfacial characterization on real
  crude oil system helps to improve operational
  design, but generalization still needed
• Chemical EOR
• HLD approach for formulation optimization
• need for robust formulation
• COMING CHALLENGE?
• high water production during reservoir
  exploitation (watercrude oil 31)
• produced water management how to give positive
  value to the water?

Workshop 2.3 Emulsion as a remediation tool
J-M. Aubry, I. Covian

• CONCLUSIONS
• Tendency to improve life time of different
  materials by the use of emulsion (ageing porous
  asphalt, remediation of soil)
• People take more and more into account the
  production of more sustainable process and
  products (life cycle)
• Most of these technologies are in a preliminary
  step and we recommend to work on it more in
  deeply.
