How to maintain a composting toilets

Here is a step by step guide on how to maintain a composting toilets:

1) Aerating Waste with Mulch

It is expected that your composting toilet will have a deep pit where you would find mulch, sawdust being an example. A container found near the composting toilet with more mulch which you will need to toss in will be found.

Sawdust and similar materials are used instead of sand because they create small pockets of air. These air pockets allow a better air circulation in the pit thus, making it easier for bacterial cultures to decompose the waste.

2) Bacterial Assistance

Most composting toilets require bacteria for waste decomposition. Two types of bacteria are found in the composting toilet pit. The first is the bad bacteria which cause diseases while the second is the commercial bacterial cultures.

The bacterial cultures get to eliminate bad bacteria while also decomposing the waste quicker and in a more efficient way. It also eliminates the smell that comes with human waste.

Maintaining Your Composting Toilet tips

2) Proper Usage of Mulch

A spare bucket filled with mulch should be placed near your composting toilet. This makes it easier for any individual who just used the toilet to reach it and have a fresh coat of mulch thrown on his/her waste. This dries out the waste and makes it much harder for flies and bad bacteria from breeding and growing in the pit.

3) Avoid Pouring Water in the Toilet

Pouring water in your pit is absolutely not a good idea. This is because the water will make the inside of the pit a sloppy mess and also make it harder and more disgusting to clean it out. Asides from that, it gives the bad bacteria and flies the opportunity to breed and grow.

4) Keep Other Waste

Human waste should be the only waste in your toilet. Other wastes such as glass, chunks of wood, e.t.c should not be found in your toilet.

These objects do not easily turn into compost like human waste. Asides from that, they will only make the cleaning of the pit more difficult and more dangerous in the case of glass. Thus, always ensure that foreign objects are thrown into a bin rather than a pit. (Recommended: Check these best books about composting here)
