◆Asuthia - Astia - Beautiful flush toilets around the world! ✨ Custom-made options are available to meet customer needs! The fixed-type circulating soil toilet is an environmentally friendly toilet system that utilizes the natural purification power to treat wastewater. By harnessing the work of microorganisms living in the soil layer, it enables a stable flush toilet environment even in areas without proper water supply and sewage systems. It is fixedly installed in buildings and can be operated stably over long periods, making it ideal for natural parks, campgrounds, mountainous facilities, and public spaces. It provides a comfortable and clean space for users without burdening nature. ◎ System replacement for disaster response By replacing only the system while keeping existing toilets in disaster evacuation sites (parks, daycare centers, schools), it ensures safe usage during power outages, water supply interruptions, or pipe bursts. ◎ Power source switching is also possible Normally, it uses the existing power supply, but it can switch to solar power during outages. ◎ System switching between normal and disaster conditions When water is available, it can be used for toilet flushing without circulation, changing only the wastewater treatment to the soil system. During disasters, it can switch to a circulating system.
