==Oil filtration==
An oil filtration system, chemical treatment, or absorbent powder ([[diatomaceous earth]] or [[synthetic magnesium silicate]]s) all help remove tiny food particles that are not always visible.  Using these systems doubles the life of the oil.{{cn|date=October 2024}} Oil filtration systems can sometimes be purchased as an enclosed part of the fryer to avoid involving employees in the somewhat dangerous process of filtering the oil with an exterior system.  Many restaurants use a portable oil filtration system to transport waste oil to a disposal area.  However, even old oil is not completely useless.  There are ways (involving other chemicals and machinery) to "[[recycle]]" old oil as [[biodiesel]] that can power diesel vehicles. Bio-diesel increases energy security<ref>{{Cite web|url=http://www.recycleutah.org/turn-cooking-oil-biodiesel/|title=Turn Your Cooking Oil into Biodiesel|last=Brooks|first=Molly|website=Recycle Utah|date=2016-11-16|archive-url=https://web.archive.org/web/20190222095212/http://www.recycleutah.org/turn-cooking-oil-biodiesel/|archive-date=2019-02-22}}</ref> resulting in many environmental benefits and even helping decrease [[greenhouse gas emissions|greenhouse emissions]]. Pouring used oil, such as fats and grease, down the drain should be avoided, as this can cause food build up and clogged pipes, restricting the flow of liquids. This often results in costly restoration and cleaning.<ref>{{Cite web|url=http://takecareoftexas.org/hot-wire/foods-you-shouldnt-wash-down-drain|title=Foods You Shouldn't Wash Down the Drain|website=Take Care of Texas|date=2018-09-24|archive-url=https://web.archive.org/web/20180930152957/http://takecareoftexas.org/hot-wire/foods-you-shouldnt-wash-down-drain|archive-date=2018-09-30}}</ref>
