Scientists at the University of Calcutta (India) have announced the discovery "shocking": eggshell can help fight climate change!
Eggshell membranes can absorb CO 2 7 times their own weight.
The study's lead author, Basab Chaudhuri, demonstrated that eggshell films can absorb greenhouse gas CO 2 by 7 times their own weight, and scientists can use eggshells. " confine "less carbon dioxide until energy efficient methods to remove this toxic waste are developed.
The eggshell consists of 3 layers: the surface epidermis, the porous layer containing calcium in the middle and the inner layer. The second and third layers include fibrous proteins that convert carbon dioxide into calcium carbonate.
The membrane is located just below the crust, about 100 micromete thick. Chaudhuri's team used a weak acid, acetic acid, to separate the membrane from the shell as a CO 2 absorber, and this mechanical separation method would be effective on an industrial scale.
On average, there are about 6824mg CO, CO 2 absorbed by each gram of eggshell membranes.
Chaudhuri also said that humans can reduce CO2 emissions after each meal with eggs due to the exposure of eggshell membranes directly to the air.
CO2 has increased significantly since the mid-nineteenth century, when fossil fuels, coal, oil, and gas began to fuel the industrial revolution. The increase in global average temperature in recent decades is largely due to the increase in the concentration of greenhouse gases in the atmosphere.
In 2005, CO 2 concentrations were three times higher than this gas before the industrial revolution. And according to statistics, nearly 300 billion tons of carbon has been released into the atmosphere through the burning of fossil fuels and cement production since 1751.
