Frequently Asked Questions

BioLet toilets have a patented “re-circulating air process” that provide the maximum amount of air throughout the mulching material. The aerobic bacteria, which cause the decomposition, thrive in oxygen rich environments. Feeding more air to these bacteria is just like feeding more air to a fire, it’s going to compost hotter and faster.
