Cooking oil out of major pollution

Being green in the truest sense of the term means that you are on the lookout for making use of what is known as refuse or waste and use resources more responsibility in the best interests of sustainability. One of these is that of creation of cooking oil by means of using a new solvent along with carbon dioxide. This technique is able to extract oil from soybeans without having any negative environmental impact that other extraction methods are infamous for.
As we all know, CO2 or carbon dioxide is the major source of global warming in the world. This is one gas that has been severely demonized as being the favorite hate gas of folks. This is one of the main reasons why researchers are on the lookout for uses of CO2 that would help offset its negative image and also make it amenable to some profitable and beneficial use.
There is a team of researchers that has created a new solvent that extracts oil from soybeans, when it is combined along with carbon dioxide. As of now cooking oil industry uses hexane to extract oil from soybeans. Hexane is not only flammable and causes air pollution, it is also a neurotoxin, which means that it can negatively impact the nervous systems of humans should they come in contact with its noxious fumes. In addition to this, the use of hexane also requires a high degree of distillation, which is an energy guzzling process.
The CO2 linked process is able to function in a much more environmentally sustainable and eco friendly manner. The new solvent is biodegradable which means it can transform from being a hydrophobic or water hating form to hydrophilic or water loving form just by the addition of CO2. This is immensely useful in extracting oil when the solvent is added to a mixture of soybeans and carbonated water
