Are there any secrets to making green onions store longer?

Hi everyone,

I recently moved into my own place and am finding that cooking for one person without waste can be difficult. I am wondering if there are any tricks to make green onions last longer so I can get through them without waste. I Googled this and the tricks often involved putting them plastic bags with damp paper towels, but I am hoping to avoid plastic waste (wasting a ziploc bag green onions seems so wrong).

Are there other ways to process/store green onions that extends their life, without needing to use and throw out disposable plastic?
