Stop vegetable oil waste
A lot of vegetable oil becomes food waste, discussion TODO: quantify: How much waste oil is produced per year globally (or perhaps, per day per capita globally) (and how much agricultural land that amounts to)? And what 'percentage of all food waste' is that? due to inefficiencies of deep frying (in restaurants, etc).
Even though this oil is often recovered by energy companies that use it as biofuel, it doesn't undo the environmental impacts of producing food that isn't eaten. Biofuel production causes more harm than fossil fuels, per unit of energy.
We can do better by not letting so much vegetable oil become inedible in the first place.
Solutions
Creative cooking
Before the oil gets bad from too much frying, stop frying with it, and use it for other recipes. [ELABORATION needed]
More efficient deep frying
How fryers produce waste oil discussion This is the technical term for it. in the first place:
- Small crumbs of food end up in the oil, and eventually become charred. As more and more of them build up from frying multiple times, the oil becomes blackened.
- The heat from frying, eventually destroys antioxidants such as vitamin E, and makes the oil more prone to becoming rancid.
