I could think of a half dozen different ways to attach a handle, but I am not sure it would be worth it. I'm all for reusing things, but five gallon buckets seem like a better option. If you look around a bit you could probably find free five gallon buckets. Restaurants tend to get ingredients in five gallon buckets and might have some in the kitchen they want rid of. Unfortunately, the kitty litter buckets are probably not recyclable due to the color. Most often only white and clear plastic is recyclable.
