Understanding Composting Toilets: A Game-Changer for RV Living
How Composting Toilets Work
Composting toilets separate liquid and solid waste into different chambers for efficient processing. The solid waste chamber contains organic material (coconut coir or peat moss) that helps break down waste through aerobic decomposition. A small ventilation fan eliminates odors by directing them outside while accelerating the composting process. Regular mixing of the composting medium speeds up decomposition, transforming waste into usable compost.

You’ll also enjoy environmental benefits by turning waste into valuable compost rather than requiring chemical treatment.
