I came across a wonderful way to compost your unused veggie scraps and other organic wastes. Use worms! Yeah, that's right those slimy little annelids, aka earthworms. I'm planning on making a worm composting bin soon just like the following video. They sale bins for worm composting, but they aren't cheap. I've tried to grow worms back when I was a Purdue, but failed because they all drowned. I'll update you soon on how the worms are doing.
