Why are compost toilets good for the environment?

Sometimes, it seems the world is in chaos. Rainforests burning. Water systems poisoned. Land being cleared for non-sustainable farming practices. Even though sometimes doing your bit to help our mother earth might seem a little overwhelming, there are things you can do that may seem small, but have a significant impact on our environment. 

Installing a composting toilet is just one way you can do your part to help the environment, and the best thing is that once it’s installed, there’s very little maintenance and upkeep required. Our range of Sun-Mar composting toilets will help the environment in a multitude of ways which we have outlined below. 

Composting toilets save you water – a lot of water 

The amount of water you save will depend on how many people are using your composting toilet and your lifestyle. Suppose, for example, you have four people in your household (let’s say two adults and two children) and one or both adults work from home. In that case, a composting toilet installed in this household will save much more water than in a sharehouse where four adults work out of the home for several hours every day. 


Installing a composting toilet can save upwards of 35,000 litres of water every single year. 


Just think if your entire street were to install composting toilets, how much water that would save every year. Now think about your entire suburb or city, and you can quickly see how installing a composting toilet will help us save such a precious commodity like water. 

Considering the dams around Brisbane (at the time of writing) are sitting at 59%, it makes a lot of sense to consider installing a composting toilet in your house to do your part in saving water in the driest continent on earth.

Composting toilets reduce our reliance on chemical processing of human waste.

If you start looking into the way a modern city processes waste, you may be surprised at the number of chemicals used. All too often as a society, we flush our waste away without giving a second thought as to where it goes or what happens to it when it gets there. 

Wastewater treatment plants use a wide range of chemicals to treat wastewater including insoluble oils, silicones, alcohols, stearates and glycols. Whilst we have agencies like the Department of Environment and Science that handles what levels of chemicals and waste are appropriate, chemical treatments will always have some impact on the environment.  

Operators are licensed under the Environmental Protection Act 1994 to discharge treated wastewater at an acceptable environmental standard into waterways; however, acceptable levels does not mean zero impact. 

If you’re looking for a way to remove yourself from the process of treating wastewater with chemicals and that water then being discharged into our water systems, a composting toilet is the only way to break this cycle. 

Composting toilets help you break away from your reliance on the grid

If you’re looking for a way to reduce your reliance on municipal services like wastewater, a composting toilet is a great way to do it. Not only will you be 100% responsible for wastewater management, but you also get a usable product at the end of it! 

If you combine your composting toilet installation with a greywater system AND solar, well… you’ve got the trifecta of getting yourself off the grid.

The biggest thing a composting toilet will change is your attitude

Instead of throwing our hands in the air when things seem useless, we can take personal responsibility for our part in how we treat the earth. Not only this, but we are responsible for teaching our children about how to live sustainably in a world where natural resources are being used at unsustainable levels. 

Installing a composting toilet may not feel like you’re ‘changing the world’ but every journey no matter how far or how long always starts with that first step.
