Action Plan for Case Studies

• Creating process flow charts
• Mass and heat balances and analysis of critical
  points
• Searching for relevant parameters
• Sankey chart
• Prevention and/or recycling of emissions and
  waste
• Zero Emissions Matrix and decision tree
• ZEW methods
• Closed loop engineering
• Heat integration and by - products
• Process optimisation
• List of measures
• Implementation of Zero Emissions Techniques
