During traditional aerobic composting, microorganisms in the soil layer use the available supply of nitrogen, carbon, and water in the compost bin to break down the kitchen waste and bedding and release nitrogen, phosphorus, and potassium, leaving behind a nutrient-rich compost.

How does an indoor composter work?

During traditional aerobic composting, microorganisms in the soil layer use the available supply of nitrogen, carbon, and water in the compost bin to break down the kitchen waste and bedding and release nitrogen, phosphorus, and potassium, leaving behind a nutrient-rich compost.

Why do indoor compost bins have holes?

Air holes are necessary to help the composting material “breathe.” The bacteria and other microbes in charge of the decomposition need oxygen to do their jobs, and without holes compost can quickly heat up through excess gas production.
