A waterless composting toilet used primarily where it is not practical or economical to install a conventional toilet. It is an on-site, self-contained, biological toilet that uses aerobic decomposition and evaporation to reduce human waste to a nutrient rich, hygienically safe "humus". The BioLets reduce the volume of waste entering the toilet by approximately 90%, leaving only 10% of the original volume for disposal. This can be recycled back to nature in a safe way w/out polluting the environment.
