On 27.07.2012 and 28.07.2012 ?The International Conference on Science and Technology for Clean and Green Environment? was organized by Zoology Wing,  Annamalai University.  I was selected by the organizing committee and my paper on ?Bio Gas from daily food waste: A renewable Energy Source: A simple way to Environmental Protection by Waste Management? was selected and published in the abstract book.  I delivered my power point presentation on my topic and the best paper award was given to me.  The conference was very useful to me and our district collector delivered a speech about ?Zero Waste Management?.   I was the only boy selected for  abstract submission and I am the youngest too.
