questionnaire - your cooking oil? {thought for the day}

what do you do with it when you are done cooking?

- - the cooking oil, oil packing (sardines, for example - packed in oil) -
- "kitchen oils," you know?

what do you do? - wash it down the drain with a bunch of hot water and
soap ?? (water waste, and carbon plus phosphate pollutions?)

this is a major resource if we recycle all that from all our kitchens, plus we would save water and stuff.
