I think Gardening is the ultimate "re-purposing"...
1. save seeds for following season
2. compost the plants from seasons end
3. use "found objects" for garden/lawn art
Well you get the idea.
I love my Lavender which I re-purpose into wands, sachets, spritzes, and use for culinary & tea.
I know it's kind of the slow way to grow (new) lavender plants but I dig up the little 'starts'...or plugs as they are called, transplant them into a recycled container, leave them sit on a sunny window, water when needed...and once they reach a good size I transplant them individually into a larger container and then by next summer when they are of a good size to transplant, out into the garden they go.
"Free Lavender"...just have to be patient while they grow.
