Don’t forget aeration, as proper air flow will assist in making the perfect compost, so your bin must have ventilation holes. Finally, how easy is it to gain access to your bin, as well as remove the compost from it? Some are constructed with trays, and others have doors, so choose the design which best works for you.

Some lids have multiple functions, such as serving as a tray to help remove compost, or designed to allow just the right amount of rain in. Make certain you purchase a compost bin with a large top opening. This way you can dispose of your grass clippings and kitchen waste quickly and easily, with little fuss.
