The BioLet NE is an on-site, self
contained, biological toilet, where human waste and toilet paper
are collected. Excess liquid is recycled through
evaporation/transpiration and solid material is decomposed to a
soil-like hygienically safe product (humus) without producing any
The BioLet NE uses no
ELECTRICITY, WATER nor CHEMICALS and requires no hookup to sewer
or septic. Just a simple installation of a vent pipe and drain
tube and you're ready to go!
The BioLet NE utilizes the
natural process of aerobic
decomposition. Within a relatively short period of time, human
waste and toilet paper are efficiently transformed into a small
amount of fertile compost. The BioLet NE reduces the volume of the
waste entering the toilet by approximately 90%, leaving only 10%
of an end-product, which can be recycled back to NATURE in a safe
way without polluting the environment.

the BioLet NE are two composting containers. When the
first container, under the seat, is filled, it is slid to
the back of the toilet for further composting. The second
container is now moved to the front. When this container
is filled, it is time to dispose of the finished compost
in the back container by trenching it into the soil, where
the nutrients will be used for new plant growth.
Freezing temperatures will NOT damage
the BioLet NE. Composting action decreases but increases quickly
when the cottage is again heated. The drain pipe must be well
insulated and installed below the frost line in the soil to
prevent clogging of the drain.
BioLet NE needs only a minimum
- Simply add 1/2 cup of starter
mulch after each fecal use.
- When both composting
containers are filled, dispose of the humus in the back
container by trenching it into the soil.

The BioLet NE doesn't have an electric heater to assist the
evaporation of excessive liquid so, it will not fully evaporate
the total volume through the vent. Therefore, it's necessary to
install a small drainage system unless the excess liquid can be
drained into an existing septic or holding tank. An outdoor or
indoor soil/planting bed will do or the excess liquid can be
collected into a container and later be used to water and
fertilize nitrogen-loving plants, or some other methods of
disposal as described in the owners manual.
Dilute with 75% water before
watering nitrogen-loving plants.
ALWAYS CONSULT YOUR LOCAL
