This is an eco-friendly bio toilet that uses a circulation and recycling system based on bio-microbial treatment, neither water-flushed nor pit latrine.

The "Bio R21" is a circulation and recycling type toilet that utilizes bio-microbial treatment. Since the toilet odor is completely eliminated, it can be used comfortably and without smell. 【Features】 ■ The substrate is made from buckwheat husks ■ Initial introduction of aerobic bacteria eliminates odors (patented) ■ Human waste and toilet paper are treated with microorganisms ■ Harmful bacteria (such as E. coli) are killed by the fermentation heat of organic matter and heater heat, allowing it to be safely returned to the earth as compost ■ Energy-saving with PTC surface heating element heater (far-infrared method) Installation location: Yumoto Substation Model: Bio R21-M type, 1 unit Option: Separate toilet Comment: Installed within the Yumoto Substation facility. It is a toilet equipped with a washlet. The Hakone Tozan Railway runs nearby. *For more details about the product, please download the PDF or feel free to contact us.
