  1. Green Chemical Engineering Domenico Pirozzi Department of Chemical Engineering University “Federico II", Naples, Italy h SIEE - China Italy Innovation Forum - Bilateral Meetings – Napoli, 19-20 nov 2012

  2. What can a Chemical Engineer do to assure that a product or a process is sustainable? Traditionaleconomiccriteria: Analysisofprofitabilityof a chemicalplant • New dimensions: • - Environmentalsustainability • Social solidarity • Economicefficiency How expensive is the transition? SIEE - China Italy Innovation Forum - Bilateral Meetings – Napoli, 19-20 nov 2012

  3. Sustainability as a central strategy Rethinking processes from different viewpoints Environmental problems cannot be solved by the level of thinking that created them! Economic profitability SIEE - China Italy Innovation Forum - Bilateral Meetings – Napoli, 19-20 nov 2012

  4. NANOTECH Intensification (scale out) Improved control GREEN ENGINEERING SMART ENGINEERING Selectivity BIOCATALYSIS Minimum energy involved Safety Risk prevention Money saving Minimum storage Flexibility to Optimization Replacement of toxic chemicals, hazardous proc. SIEE - China Italy Innovation Forum - Bilateral Meetings – Napoli, 19-20 nov 2012

  5. Biomimicry : natural standards offer the more efficient solutions King Fisher Learn rather than extract from! Shinkansen SIEE - China Italy Innovation Forum - Bilateral Meetings – Napoli, 19-20 nov 2012
