Compostable Toilet – What is that?

When discussing waterless toilets, the term “compostable toilet” sometimes comes up. However, this term is technically incorrect. The proper terminology is “compost” or “composting toilet”. Although you might not think, it the case of waterless toilets, the terminology actually matters. Therefore, in this blog post, we’ll explore what composting toilets are, how they work, and why the terminology matters.

What is a Composting Toilet

A composting toilet is a type of waterless toilet that treats human waste through aerobic decomposition. This process transforms waste into compost, a nutrient-rich material that can be used to enrich soil. Unlike conventional toilets that require water and a sewage system, composting toilets operate without water, making them ideal for remote locations, off-grid living, and environmentally conscious households.

Why Not a Compostable Toilet

The term “compostable toilet” might seem logical at first glance, but it is somewhat misleading and technically incorrect. The confusion arises from the implication that the toilet itself is composted, which is not the case. Instead, it is the human waste within the toilet that undergoes the composting process, either inside the unit or elsewhere.

When people refer to “compostable toilets,” they often intend to describe a toilet that facilitates the composting of human waste. However, composting toilets, as the correct term suggests, are designed to manage and transform waste into compost through aerobic decomposition. The toilet itself remains intact and operational, while the waste it collects is what becomes compost.

Why Precision in Terminology Matters

Many assume that all waterless toilets are composting toilets, which is not the case. There are various types of waterless toilets, including composting, incinerating, and urine-diverting toilets, each with different mechanisms and outcomes for waste management. Compounding the confusion, some manufacturers intentionally misuse the term “composting toilet” to market their products, even if they are not true composting toilets. This can mislead consumers into thinking they are purchasing a system that composts waste in itself when, in fact, it does not. Such misrepresentation underscores the importance of understanding the specific functionalities and processes involved in different types of waterless toilets.


In summary, while the term “compostable toilet” may be commonly used, it is not accurate. The correct term is “composting toilet,” which accurately reflects the process of composting human waste within or through the system. By using the right terminology, we can help clarify the benefits and functionality of these eco-friendly sanitation solutions, ultimately promoting their wider acceptance and usage in the quest for sustainable living.
