I have a bunch of gallon plastic bottles of water from my emergency cache that need to be used up. Despite the fact that they're in plastic, in an emergency it is water so I need to keep some around. I'll set these aside and get new ones.

But the old bottles aren't going to be drunk. I took a jug, poured off a little, and added some of my Garrett Juice (a compost tea mix that you can make yourself or is bottled and sold at local nurseries) and some Hasta Grow (a marginal, not quite organic liquid fertilizer that Garrett tolerates because it is so much better than the blue stuff). Marked it with a Sharpie pen so no one mistakes it as a jug of iced tea and I'm set for my potted and house plants. ;)
