The secret behind how a composting toilet works is thru the use of a “urine diverter” which separates the liquids and solids. Dont be fooled, a toilet that doesn’t rely on a urine diverter is not a composting toilet. Separation of the liquids and solids maintains a dry environment which is essential for initiating the composting process. Simply put, there is no odor because the composting medium wicks moisture from the solid waste. Road commode, a great addition to any.
