What is Windrow Composting?
Windrow composting is a method of aerobic composting in which organic materials are arranged in long, narrow piles called windrows that are regularly turned to maintain oxygen flow and promote microbial decomposition.

Windrow composting is widely used in municipal yard waste programs, agriculture, and commercial composting facilities. Turning the rows helps regulate temperature, moisture, and airflow, all of which support efficient microbial activity. This approach differs from in-vessel composting, which occurs in enclosed and more controlled environments, and from aerated static pile composting, which requires minimal turning. Windrow systems are valued for their cost effectiveness, scalability, and suitability for managing large volumes of organic materials.
