Years ago I started making soap with used oil that we all have in our kitchens. Vice jabonero Once entered into my veins, followed soap with new oils and left a bit left the soap recycling. At first I accumulated the fryer oil stored them in plastic pots, but now my husband has found a way to put it to use: biodiesel. The process for making biodiesel is very similar to soap making, a little more complex and precise, but basically very similar. It is economically and environmentally intersante use used oil, give it a second life to a highly polluting waste product and can be used in heating and of course, in our car, with a zero balance in terms of CO2 emissions.
oil conversion used in biodiesel is called transesterification and the chemical reaction we get a methyl ester (biodiesel), glycerin and a little soap. Reagents to achieve this prodigious change than methanol (an alcohol) and lye (an alkali), in such proportions as to dictate the quality of oil that we will use.
