Haven't heard of any of these detox sustainability events up my way yet. Sounds like a great idea. My shed could definitely do with a "detoxing" lol!

I'm laughing at some of the solutions proposed here, like putting it on weeds along fencelines. I can imagine the look of horror on my neighbour's face if I had just done the fenceline and he gets out with his gas weed wand. He's merrily burning off the weeds around his pavers, then decides to hit a few along the fenceline. Woosh, instant "scorched earth"! devilchilli
