Composting toilets are typically made of plastic, ceramic, or fiberglass, and generally have two primary components — the toilet and the composting tank.

The composting tank often includes a fan to help manage odor. While all composting toilets function in virtually the same manner, cost and maintenance requirements vary widely from product-to-product. Many products use solar panels to provide the electricity. An important distinction is the difference between self-contained and centralized systems.

Self-contained systems are sold as a single-unit and are generally used in rural, single family residential applications as they cannot process large volumes of waste.

In a centralized system also known as a remote system , the toilet connects to a composting tank that is usually located below grade. Centralized systems can process more waste than self-contained systems and are generally installed in remote areas for hikers and campers. When selecting a composting toilet model, it is critical to select a model that is appropriately sized to meet the demands of the anticipated number of people per day.

The standard requires a minimum of six months of performance testing, which includes design loading and stress testing appropriate to three product classes: residential, cottage, or day-use park. There are many certified composting toilet models available for purchase. In addition to proper installation, the proper maintenance of composting toilets is critical to ensure ongoing safe operation and the avoidance of health hazards and odors. Maintenance requirements vary from system to system — understanding the maintenance requirements and schedule of your composting toilet is essential.

Many companies offer maintenance services by trained and licensed professionals. Please consult with the vendor of your composting toilet to fully understand the maintenance requirements. Maintenance for the composting toilet will be driven by the amount of daily use and the model of toilet selected. Some general maintenance requirements of composting toilets include:.
