Handing food wast

Handing food remnants is the problem.
My daughter and I both hate to cleaning food waste. So, I put the food waste in a plastic bag and then put it in refrigerator to freeze it right after finishing eating.
It could prevent bad smells when I throw it away. But my daughter gets angry about it because she thought food waste is a wast thinks leftover food should be thrown away even though it was not rotten.
Of course, food wast and food remnant are looked rotten food and leftovers look totally different but she just feels bad or thinks differently.
My daughter and I both hate stinky food waste.
How could I persuade her that I could freeze food waste?
What should we do?

Well-stated, Sanghyeon! I'm sorry this is a big issue in your household. 

I marked some corrections in red. "Waste" always has an "e" at the end! 

One solution may be to decide beforehand some food that can be saved, and some food that can automatically be disposed of?

For example, if you were going to cook some meat, that could always be saved for leftovers. But, some side dishes can be thrown out right away if there are leftovers.

Also, unless your daughter takes out the trash, she should be more agreeable with papa!!

I will try to think of another solution. Excellent composition! Let's discuss it next class!
