This is a super frugal and easy way to make a compost bin. Three milkcrates are prepared and then stacked. You make a lid for the top and you are all ready to begin composting. The first bin is used to add new waste to and when filled is moved to the middle, once that has broken down well you move the material to the bottom to finish making compost meanwhile rotating top and middle crates to have a fresh bin to add to all the time.
