Brochure "Bio Toilet Q&A You Should Know When Selecting"

Packed with tips on how to choose a reliable bio toilet! Explaining useful information before and after installation in a Q&A format!

A bio toilet used as a "comfortable toilet" in direct-controlled projects by the Ministry of Land, Infrastructure, Transport and Tourism. It activates microorganisms using the power of nature to break down human waste. We are currently offering a booklet titled "Q&A You Should Know When Selecting a Bio Toilet" from our company, which specializes in bio toilets! In particular, we have compiled content that we would like those who have previously experienced failures with bio toilets to read. For example: "I had to replace the sawdust frequently, and it ended up being costly." "It smelled worse than a pit toilet, and I never want to use a bio toilet again!" We summarize the key points for choosing a bio toilet without making mistakes and present them in a Q&A format. 【Examples of Q&A included】 ■ What is a bio toilet? ■ What should I be careful about when choosing a bio toilet? ■ Common questions about "Bio Micaret" ■ What is the difference between "Bio Micaret" and other companies' bio toilets? *For product details, please download the PDF document or contact us.

No unpleasant odor even with long-term use! Case study No. 1 of introducing biomicrolet.

Installed in many long-term sites where it is difficult to draw sewage due to the inability to connect to the sewer system, with no worries about freezing even in winter.

"Biomikaret" is a temporary bio-toilet that can powerfully decompose waste by activating microorganisms with an internal heater. This time, we would like to introduce a case where it was adopted at a long-term site in Fukushima Prefecture! At this site, there is no sewer system, making it difficult to pump out waste. One of the four units was installed as a women's toilet, but last year, due to low temperatures, the water pipes burst, leading to many incidents where the toilet became unusable. Therefore, for the first time, we adopted Biomikaret. As a result, we were very pleased to report that there were no troubles during the winter. [Effects of Implementation] ■ No worries about freezing even in winter ■ Improvement in troubles related to toilet usability ■ Helped with freezing measures such as preventing water pipes from bursting due to low temperatures *For more details about the product, please download the PDF or contact us.

[Case Study] Installation Example of Water-Flushing Bio-Toilets at Historical Sites

Proven reliability and simplicity in various situations. Can be installed anywhere as it does not require a sewer system.

We would like to introduce a case where a waterless bio-toilet was installed at the site of the Hara Castle ruins in Minami Shimabara City, Nagasaki Prefecture, which is close to being registered as a World Heritage Site. Due to the historical nature of the site, excavation and other activities were not possible, and there was a request for a toilet that does not require water supply and drainage, while also being environmentally friendly. The toilet was installed to ensure that tourists can use it comfortably and without odors, just like any regular facility. To receive registrations as a World Heritage Site, Japanese Heritage, Eco Park, Geo Park, etc., it is also important to develop toilets that are environmentally considerate and comfortable to use. 【Construction Case】 ■ October 2016 ■ Building + Treatment System Installation ■ Treatment Capacity: Maximum 150 uses/day *For more details, please refer to the PDF document or feel free to contact us.
