Worm farm is a great idea. I'm getting ready to setup one for my food scraps. I'm also going to see if I can get my work colleagues to give me their food scraps. I'm just going to put a small bin (with a lid) in the break room with a sign that says what the worms like and what they don't. It is a small office so I'm hoping it will work. Got to do what we can to make a difference! Plus, worm castings are great for gardens :)
