mulches will carry the BioLet Toilet Systems 
logo. Using any other mulch may cause a 
decrease in the efficiency of your toilet and may 
void the warranty on parts if their failure is 
determined to be caused by usage of 
unapproved mulch. 

Homemade mulch 

If you desire to make your own mulch you can 
use the following recipe for 10 gallons of starter 
mulch: 

 

6 ½ gal – Blond high fibrous, Canadian 
sphagnum peat moss (

ALL PEAT MOSS IS 

NOT THE SAME

 

3 ½ gal - Pine wood shavings (obtainable 
from nearly any livestock feed store as 
livestock bedding) 

DO NOT USE 

SAWDUST OR CHAINSAW CHIPS

 

 

2 cups – Good rich garden soil from first 6” 
layer of soil (

ENSURE FROM AN AREA 

WHERE PESTICIDES ARE NOT USED

 

1 pound – Dry molasses. 

 

1 pound – Hulls of buckwheat, wheat, 
peanuts or cocoa. 

 

1 pound – Coarse Perlite 

Keep your mixture dry and allow it to breathe. 
Except for when starting your BTS 33, do not 
dampen. The mulch will mix in and dampen 
with bathroom use.  

*** IMPORTANT *** 

BioLet Toilet Systems cannot guarantee the 
operation of your unit unless you are using 
approved mulch.  

Emptying the Compost Bin 

In a full-time residential setting, the compost bin 
should be emptied when the bin is about 3/4 the way 
full or once every 6 months, whichever comes first. 
In a part-time cabin/cottage setting, the compost bin 
should be emptied when the bin is about 3/4 the way 
full or once a year whichever comes first. 

1. 

Remove the top of the toilet by lifting straight up. 

2. 

Position the compost bin lid on top of the 
compost bin and press down firmly on the outer 
edges to lock the bin in place. 

3. 

Move bin handle into upwards position. 

4. 

Slowly lift on handle until you are sure it is safe 
to carry out the bin. 

5. 

Remove the primary bin and move it outside to 
finish composting. 

6. 

Place the secondary bin into the unit with the 
curved end facing the front of the unit. 

7. 

Pour in 2 gallons of Starter Mulch to make a 2” – 
3” covering inside the bin. 

8. 

Replace the top of the unit, ensuring it is evenly 
sitting on the base. 

If the secondary bin contains humus, dispose of 
it by adding it to an existing outside compost 
pile for finishing or when an existing compost 
pile is not available, by mixing it with soil or 
compost and trench it in around ornamental 
trees and plants and cover it with a minimum of 
5" topsoil, or dispose of it in a manner approved 
by your local health authorities. 

Shutting down your toilet 

If your BTS 33 is going to be idle and not used for 
periods of two days or more: 

Add about one quart of humus starter per week that 
you will be away or one gallon (whichever is less) 
and mix it well into the compost. 

When you are ready to use the toilet again: 

 

Visually inspect the material inside to ensure 
it is moist. 

 

If necessary add enough water to moisten 
the material. 

 

Mix the material. 

In case of paper build up 

If a build-up of toilet paper occurs, sprinkle a small 
amount of water over it to make it dissolve and mix 
into the compost. 

Cleaning 

Use a sponge or sponge style toilet brush and liquid 
soap or some other mild detergent when cleaning 
your BTS 33. Never use scouring powder or other 
strong detergent that could scratch the surface. 

Insect control 

The presence of insects in and around your BTS 33 
is frequently an indication of excess moisture. If 
there is excess moisture you will need to remedy this 
situation to be able to completely remove the insects 
from your toilet. Use of mulch not authorized for use 
in your BTS 33 may also introduce insect larvae into 
your toilet. 

To rid your toilet of insects: Insert a Hot-Shot No 
Pest Strip (blue and white envelope type package), 
Spectracide Bug Stop Pest Strip (green and yellow 
envelope type package) or similar product 
containing Dichlorvos as the ONLY active ingredient 
inside the unit but outside the compost bin. These 
items are readily available at your local hardware 
store or department store in their garden centers. 

Helpful hints 

 

Keep a small sealed container, with starter 
mulch and a ½ cup measurer in it, next to 
the toilet for convenience of adding mulch 
after each fecal use.
