A : n Japan, we cook lots of deep-fried food and most households have a Cooking oil container with a strainer. I bought one when I went back to Japan. I reuse deep fry oil 2-3 times. Draining the deep fried oil down the kitchen sink pipe is not good for the environment. When I throw the oil, I scrunch a few kitchen paper towels in a milk carton and drain the oil into it. Seal the milk carton and throw it in the bin.
