Kazuba™ | STK System

The best performing Desiccating Dry Toilet System on the market

Features aerodynamic ventilation curve for maximum airflow

Each Kazuba™ STK system is designed to handle over 30 uses per day, offering a waterless, eco-friendly solution that thrives on the power of the sun and wind. The system evaporates all liquids and dehydrates solid waste into a safe, inert material, which can be easily disposed of on or off-site.

Whether in cold or warm climates, the Kazuba™ performs reliably as long as it’s placed in an open space with access to sunlight and wind. With its odourless operation and zero discharge, it can be positioned in places where traditional septic systems can’t go—such as near sensitive waterways—making it the perfect sustainable solution for a wide range of locations.

• Solar and wind powered
• Evaporates urine
• Dehydrates solids, reducing their volume by up to 90%
• Quick and easy to assemble and install
• Simple to maintain
