Bio Toilet "Violet BT-L Type" for 40 uses per day
Bio Toilet "Violet BT-L Type" for 40 uses per day

500,000 yen-1 million yen

 (Features) ○ No need for waste removal → Waste is decomposed into water and carbon dioxide through the Acidoro composting method. → Contributes to reducing maintenance costs associated with the waste removal and purification processes that were essential in traditional portable toilets. ○ No need for flushing water → Can be used without flushing water, allowing for installation without plumbing work. Contributes to reducing initial costs. ○ Long-lasting decomposition power → The Acidoro composting method has a long-lasting decomposition effect, allowing for use over an extended period (with over 10 years of proven performance) without the need for additional or replacement materials. → If used correctly and within the recommended usage frequency, running costs can be significantly reduced. ○ Minimal odor → The decomposition of waste through the Acidoro composting method occurs under acidic conditions. As a result, the volatilization of ammonia, one of the causes of odor, is suppressed, reducing the characteristic odors associated with non-flushing toilets. ● For more details, please download the catalog or contact us. 【Installation Examples】 ○ Temporary toilets for construction sites, rental toilets ○ Temporary toilets for environmental events ○ Workers' break area at Fukushima Daiichi Nuclear Power Plant (from late July 2011) ○ Permanent toilets in natural parks "Sukegawa City Citizen's Forest" (Ibaraki Prefecture, Hitachi City) ○ Railway vehicles (Ryuhyo Norokko Train, Kushiro Wetland Norokko Train operated by JR Hokkaido) → The "Ryuhyo Norokko Train," which operates in mid-winter, has a bio-type waste treatment tank that is directly exposed to wind and snow under the vehicle's floor. Despite the harsh environmental conditions where the surface of the treatment tank can freeze, it has been functioning smoothly and successfully passed operational tests.
