CO2 IS VALUABLE, DON'T WASTE IT, RECYCLE IT!
Total CO2 emission by 2010 is 9 giga ton
METHODOLOGYMETHODOLOGY

CO2 capture & storage
Design a suitable bypass duct at the power plant site i.e. near chimney Estimation of CO2 gas Design a gate nano membrane to separate CO2 from exhaust gas using a force balance approach and reactive multiphase flow. Capture CO2 using absorbent (NANO)CO2 recycling

CO2 is that it is a highly stable gas
The new technique enables the conversion of CO2 into fuels.
The new technique is a suitable alternative .
In the first stage, water molecules are converted to free 'protons' (hydrogen ions), electrons and oxygen gas.
Water molecules
In the second stage, free electrons are used to reduce the CO2 and bind the carbon atoms together using platinum and palladium catalysts .

CO2 will not be a problem for green
house effect. Reduction in pollution level Energy crisis will be solved.
Use of CO2 in medical field.
Drinkable water obtained.
CONCLUSIONCONCLUSION
Recycling of CORecycling of CO22 - a very useful and - a very useful and
productive step in controlling global warming productive step in controlling global warming and keeping Mother Earth green.and keeping Mother Earth green.
