Saving paint from old tubes changed my watercolor game

Tbh, I was sorting through my art stuff and saw a pile of watercolor tubes with just a little paint left. I squeezed all the leftovers into a clean palette to make new pans, which was a bit messy but fun. Now I have fresh colors without buying more plastic. This got me thinking about trash from art supplies. I also save my painting water for my garden plants instead of wasting it. It feels good to cut down on waste. Does anyone else try to paint in a more eco-friendly way? Maybe you use recycled paper or natural brushes?
