The camping cooperatives need affordable and environment friendly sanitation options for mountains. This article reviews one of such options available in the market, Bianics Toilet.

What is a Bianics toilet?

This bio toilet disposes human excrements using no or very less water. The environment friendly toilet uses Japanese technology. Dr. Toyohiro Watanabe, an agriculture professor at Tsuru University, developed this portable toilet.

The commode installed in the toilet resembles the commode you use every day.

How does a Bianics toilet work? 3-Stage Process

Tips

Do not dump toilet papers and tissue papers into the toilets. Because these products do not decompose easily.

However, the method used for the excreta decomposition is different: 3-stage process.

Stage 1: While you are using the toilet, the urine or excreta gathers into the regulating tank equipped with a cutter pump. The pump stirs the waste.

Stage 2: The resulting semi-liquid substance flows to the anereation tank appointed with a screen. The screen filters foreign substances, including toilet papers. Then the waste flows into the aeration tank with a blower pump.

Stage 3: Then the waste flows to the reactor tank containing cedar chips hosting micro-organisms. These organisms converts the waste into carbon dioxide, water, and other components and prevents foul smell. This water is sent back to the toilet tank for reuse. This breakdown process kills disease producing colon bacillus.

You can replace cedar chips with saw dust.

This 3-stage process produces waste that doubles as manure for agriculture. Remove this waste regularly every year.

The toilet tent can collect rain water for flush.
