Product description

Loowatt System™ is a revolutionary waterless flush toilet system that tackles water scarcity and sanitation challenges by utilizing a patented sealing mechanism to package waste in biodegradable film. This innovative approach eliminates odors and hygienically contains pathogens, providing a sustainable solution for various settings.

The system operates by collecting cartridges filled with waste, which are then processed by anaerobic digesters. This process converts the waste into valuable resources such as biogas and nutrient-rich fertilizer. By deploying the Loowatt System™ at scale in event venues, slum settlements, and household installations, it saves over 3,600 L of water per user annually.

Designed for easy servicing and maintenance, the system not only addresses sanitation needs but also contributes to the circular economy. It offers high user satisfaction while delivering significant environmental and social benefits.
