In-vessel composting processes organic waste inside an enclosed container, drum, or silo, where temperature, moisture, and airflow can be closely controlled.
How it works
Material is loaded into the vessel and mechanically turned or aerated. Because conditions are managed, the EPA notes it can handle large amounts, work in a small footprint, and process a wide range of food waste quickly.
Pros and cons
It is fast, contained, and space-efficient, which suits schools, campuses, and businesses, but the equipment is a significant investment.
