The environmental benefits of using a composting toilet are numerous:
Conventional ‘waste’ treatment systems (both sewer and septic systems) mix human waste with a large amount of water, and both discharge most of the nutrients into water: sewers into oceans, bays, and rivers; septic systems indirectly into groundwater. In oceans, rivers, and bays this causes first, the proliferation of aquatic plant life, then, as the plant life dies and decays, the removal of oxygen from the water and finally, the destruction of habitat.
Clivus Multrum composting toilet solutions evaporate excess liquid and diffuses it into the atmosphere, meaning no contaminated polluted water is released unnecessarily into our water supplies. Any liquid that is not evaporated flows through an excess liquid drain into a small gravel pit. This may be only 1.5 litres per person per day compared with a septic system which can allow seepage of up to 125 litres per person per day (sewerage mixed with all other greywater).
Save water, electricity and therefore money
Clivus Multrum waterless composting toilet solutions do not require power or water. No chemicals are required either.
Our waterless composting toilets use absolutely no water, as against a conventional flush toilet which can consume around 60,000 litres a year. With more and more councils imposing charges on water consumption, this saving converts to dollars!
For nearly all of our agricultural history, humans have practiced sustainable farming, including the use of composted human waste for fertilizer. Only in the second half of the 20th century did people begin to abandon the principles of reuse that were once required by our circumstances.
The benefit of a composting toilet is that aerobic bacteria works to break down human waste into useable elements like water and carbon dioxide. Both of these are dissolved into the atmosphere, along with the residual moisture that is evaporated.
What remains of the waste has reduced in volume by about 90% and is chemically, biologically and aesthetically similar to topsoil. This dry-compost material is collected via the inspection door and can be used as garden compost.
