I never throw out my dishwashing liquid bottles, all of which always have a little liquid at the bottom. I save them until I am running low (on both cash and soap!) and pour them all into one bottle, sometimes making another entire bottle! And it's always a unique color!
You can also use what's left to bathe the dog or wash your car or fill in as laundry soap if you are out. I have cooking oil in one to use in the kitchen.
You can add some water to the soap remaining in the "empty" bottle then pour it under running water into your sink. There is usually enough soap to wash a sinkful of dishes, then the bottle is truly empty & can be recycled.
