I’ve been having fun with my “Waste Optimization Challenge” experiment so far – and apart from “Day 3”, I’ve remembered to take pictures every day. It’s always interesting to look back to the starting image when doing (photo) experiments like this. While it may seem pretty obvious that changes are taking place from one day to the next, I’m always surprised by just how much change has taken place when I look back through the previous pics.
Below I have included pictures from Day 0, Day 4, and Day 6 (today). Not too surprisingly, the frozen carrots are breaking down more readily than the fresh carrots. The carrot peelings (frozen, thawed, and aged) are all but gone now, so it’s safe to say we have a clear “winner” (again no surprises there).
Looking a bit more closely, we can see that the originally-fresh carrots are being invaded now, but there’s no doubt that freezing alone can lead to much faster microbial-colonization – which then draws in the springtails (visible in the lower image) and worms!
Speaking of worms…I’ve been careful not to disturb the various treatments too much, in an effort to avoid any further mechanical break-down, so I really haven’t seen too many of them thus far. The ones I did see were underneath the peelings. I have little doubt that if I dug around in that part of the bin there would be a nice concentration of them just under the surface (likely quite a few of them underneath the previously-frozen carrot disks as well).
I’m now interested to see what happens with the remaining treatments. I’m sure the previously-frozen carrot disks will be the next ones to disappear, but I’m not 100% sure how fast the whole carrot will break-down in comparison to the once-fresh carrot disks!
