Rotating Composting Barrel

For this project, I used 4x4 posts, 2x6 boards, rivets, door and locking latches, roller wheels, and a 30-gallon drum barrel. I built the stand with the 4x4 and 2x6 boards. I spread them out to allow enough room for dumping into a bucket or tote. I drilled holes into the barrel for airflow. I cut a door for loading and unloading. Inside the barrel, I attached cross boards to allow the mix to be stirred as it tumbles. I layer in greens and brown waste along with coffee grounds, egg shells, cardboard toilet paper rolls, and some soil from the garden that has microbes. I water it weekly and give it a few tumbles. This season I produced 6 gallons of compost.
