eggshells and global warming

Calcutta, India, Waste egg shell or the skin seems not many people utilized. But a recent study found that eggshells can help address climate change.

Researchers from the University of Calcutta, India, has shown that the membrane that lines the shell of the egg can absorb the greenhouse gas carbon dioxide from the atmosphere, almost seven times the weight of the egg itself.

"Carbon dioxide is a snare can temporarily be stored in this form, to the effective energy method for using this gas can be found. Later hoped would not happen again environmental problems associated carbon emissions," said Basab Chaudhuri, lead investigator from the University of Calcutta, as Medindia reported on Monday (1/11/2010).

Chaudhuri explains that the eggshell consists of three layers, namely the cuticle on the outer layer, and the calcium content in the middle layer and chewy inside.

The middle layer consists of fibers and the protein bound to the calcium carbonate. This membrane that can absorb CO2 and is right under the skin with a thickness of about 100 micrometers.

"To get this membrane, we have to separate the membrane from the cuticle. The separation membrane is currently not an efficient process," said Chaudhuri.

But according to researchers led by Chaudhuri, weak acids can help and can be used to separate the membrane from the shell to be used as an adsorbent (sinks) of carbon dioxide.

"This mechanical separation will be made for industrial scale processes. However, everyone also can reduce CO2 levels by exposing the membrane to the eggshell after eating eggs," lid Chaudhuri.

This study has been published in the International Journal of Global Warming in October.
