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 inefficient deep frying methods used by restaurants. Even though this oil is often recovered by energy companies that use it as biofuel, it doesn't undo the environmental impact of producing food that doesn't get eaten
Solutions
More efficient deep fryer designs
This section has not been filled in yet. discussion TODO: compare to status quo. Important metric: Ratio: {waste oil output} / {oil input}
Creative cooking
Before the oil gets bad from too much frying, stop frying with it, and use it for other recipes. [ELABORATION needed]
