Tools & Materials: All that you will need to build a waste composter is a shovel, a saw, a drill, 4" pvc pipe, and a vessel of some sort.
First find your vessel. I decided to use a salvaged plastic 55-gallon barrel and give it a third life. A 5-gallon bucket or a trash can would work if you have a small dog. Rather than recycling the barrel I simply reused it. I got it from our local coffee roaster and used it as a leaf composter for a couple years. Be careful that you don't use a barrel that may have had toxic chemicals in it. Mine used to be full of French vanilla flavoring. That stuff is fairly harmless.
