As we all know that CO2 emissions is posing a great threat to us by largely affecting our planet earth through greenhouse effect. Therefore we need to have some provision for reducing the emission of these greenhouse gases, and this is the reason why Scientists have developed a machine, that can trap CO2 from air thereby cutting the CO2 emissions drastically from automobiles sector.
This machine actually captures CO2 with sodium hydroxide, better known as lye. The CO2 can then be extracted and from there, stored. David Keith, professor of petroleum & chemical engineering conducted a study along with his team from Calgary University which demonstrated how to trap traces of carbon dioxide CO2 present in the air , with a simple machine.
According to keith, this machine is capable of capturing 20 tons of CO2 on a square meter of scrubbing material with in a time duration of one year.
