[Trivia Information] Bio Clean News November 2018 Edition

A case study on the introduction of solar-powered bio-toilets to mountain cabins has been published!

Our bio toilet has been adopted by a mountain lodge. Previously, they had a chair in the toilet room where a plastic bag could be set, operating on a "take your own waste back" system. However, they faced difficulties with people leaving their waste behind or discarding it along the hiking trails. To address this, they installed solar panels on the roof of the lodge and introduced our bio toilet "Violet BT-L" (which can be used up to 40 times a day). At first, users were unsure how to use it, but they successfully navigated the hiking season from June to October and have reported that they completed this season's operations without any issues. [Contents] ■ The potential of solar-powered bio toilets ■ Nutrient components of Asidoro compost *For more details, please refer to the PDF document or feel free to contact us.

Self-cleaning circular bio toilet 'A.Q' [NETIS registered]

Since it does not require pumping, it is effective in places where access is difficult, such as construction sites! This is a bio-toilet that does not require connection to water supply and drainage due to its circular design.

The "A.Q" is a self-contained, self-processing toilet equipped with a device that purifies wastewater through the action of microorganisms and recycles it into cleaning water. Being a circular system, it does not require connection to water supply or sewage systems, and by treating sludge through fermentation technology with microorganisms, it does not produce unpleasant odors and does not require pumping out. Furthermore, sterilization with chemicals is unnecessary, allowing for zero E. coli. While electricity is needed for the aeration blower and transfer pump, a small generator can be used in case of a power outage. The toilet features a washlet and is designed to achieve the same quality as household toilets, making it eligible for comfort toilet subsidies. It is a sustainable toilet that is effective both in normal times and during disasters. *For more details, please download the catalog or feel free to contact us. [Notice] This product received the "Grand Prize" at the 10th Japan Resilience Award (Resilience Award) 2024. https://www.chodai.co.jp/news/2024/04/015108.html [This product is provided by our group company, Chodai Co., Ltd.]
