How Does a Composting Toilet Work?

We have all been taught the flush-and-forget system: We don’t see where it goes and we don’t have to deal with it (you know “out of sight, out of mind”). Wastewater treatment is extremely energy intensive and the world as a whole shouldn’t continue using perfectly good drinking water to flush away our waste.

So have you ever think about a composting toilet and how it work? This information below will give you a better view of a composting toilet and how does it work?

How does a composting toilet work?

Composting toilets can be match with some places such as a rural area or a park that lacks of a suitable water supply, sewers and sewage treatment condition. They can also help to gain the resilience of existing sanitation systems in the face of possible natural disasters such as earthquakes, tsunami or the changing of climate. It can also reduce or maybe eliminate the need for a septic tank system to reduce environmental pollution.

Composting toilets use the natural procedure of decomposition and evaporation to recycle human waste. Waste going through the toilets is over 90% water, which will evaporate and carry back to the atmosphere through the vent system. A small amount of remaining solid material (this is a best part of using this kind of toilet) is transformed to useful fertilizing soil by natural decomposition.

A composting toilet must contain three totally separate processes:

Storage and compost the waste and toilet paper quickly and without any odour.

Make sure that the finished compost is safe and easy to handle.

Evaporate the liquid.

These natural process above basically the same as your gardening composter, is increased in commercial composting toilets by using the environment in the composting chamber.

Most of the composting toilets are installed right above their waste collection chambers. Waste is mixed with sawdust, wood chips or other dry material to soak up moisture and reach to the ideal carbon-nitrogen ratio. Over time and with the correct combination of temperature, drainage, aeration and ventilation, waste breaks down and drastically decreases in volume. All of composted human waste can be used in their gardening or combined with an outdoor compost pile.

Composition: Waste composts best with a rate 30:1 carbon - nitrogen ratio. Human waste, especially urine has a high nitrogen content, which means that carbonaceous material must be put in. Sawdust, wood chips and straw are common choices. Kitchen compost can be added to the same waste chamber, but such food scraps should be accreted with carbonaceous material as well.

Drainage: Too much liquid can interfere with composting by cooling waste and hindering aerobic conditions. Some liquid evaporates base on the heat in the chamber, but this procedure may not enough to avoid overly damp compost. Many owners choose to split urine from feces with a device that placed under the toilet seat or by setting a drain in the bottom of the waste chamber. These ways can prevent excess liquid from pooling at the bottom of the chamber. Liquid waste can be processed with greywater or diluted with water and used to fertilize plants.

Temperature: Heat speeds up the composting process and kills pathogens in human waste. Decomposition generates heat and compost will be hottest in the center of the pile. A large compost pile retains heat better, so the waste chamber should be big enough for a good amount of collected compost (but not so big that heat is lost in a huge or empty space). If the chamber is too small to heat up for fast decomposition or liquid evaporation, a heater may be added.

Aeration: Aerobic decomposition is faster and is not produce the odors that anaerobic decay does. Beside that, waste must have a certain amount of air throughout the pile to maintain aerobic conditions. This can be achieved by turning or mixing the compost or layering coarse materials with the waste so air is trapped in the pile.

Ventilation: Vents and fans pull air into the composting chamber to prevent bad smell from running out into the bathroom. They also let the oxygen to enter the waste chamber.

Waste should be allowed to decompose for at least a year before it can be considered safe to use as the fertilizer for the plant.

The correct poise between oxygen, moisture, heat and organic material is required to ensure a rich environment for the aerobic bacteria that change the waste into fertilizing soil. This will make sure for odor-free operation and complete decomposition of waste.

When human waste is properly composted, at the end the product does not include any pathogens or viruses (these are destroyed by bacterial breakdown). This nutrient-rich fertilizer can be used for plants or around the base of trees, as part of the natural cycling of nutrients, decreasing your need for commercial fertilizers and preserving local water quality.

To conclusion, I think a composting toilet is a worth experience to all of us. Have you ever used a composting toilet? If not, would you install one in your home?
