1. A story of bottled water
Energy conservation is in your hands Being removed in time Energy is being used
Being removed in space
1950s - SO2, CH3Cl, NH3... Is replaced by CFCs ??? – HCFCs is introduced as alternative ??? – FCs, HFCs are introduced 1990 – FCs, HFCs, HCFCs are being phased out

Energy conservation is in your hands And being removed from future generation
Let’s talk about bottled water
NOW, LET’S TALK ABOUT A FULL STORY OF A PLASTIC BOTTLE

• Crude oil (raw material)
• Resin
• Bottle production
• Filling, bottling, testing, labeling...
• Chilling, using
• Collection • Disposal • Recycling
Energy implication of bottled water Gleick and Cooley (2009)
1. Energy required to manufacture plastic: - From oil to PET resin: 4.38 kgCO2e per kilogram of PET resin or 4.38/0.744 = 5.887 kwh
1 kwh electricity is equipvalent to 0.744 kgCO2e
2. Energy required to manufacture plastic bottles: - From resin to PET bottles: 0.23 kgCO2e per kilogram of PET bottles or 0.23/0.744 = 0.309 kwh
1 kwh electricity is equipvalent to 0.744 kgCO2e
3. Energy required to process water - From tap water after ultrafiltration filter: 100kwh/million liters of purified water
4. Energy required to process cleaning, filling, testing, labeling... - The total energy required to clean, fill, seal, label and package bottle water is around: 14 MJ (thermal) or 42 MJ (electrical) / 1000 bottles = 11.634 kwh / 1000 bottles.
5. Energy required to transport bottled water The following energy transportation cost required to transport 1 ton of cargo per 10 kilometer distance
0.055 kgCO2e per ton of cargo per 10km or 0.055/0.744 = 0.074 kwh
6. Energy to cool water before use It is estimated that the energy to cool 1 liter of water at 17C and maintain that temperature 1 week requires 349kwh / m3 of water
