Sustainability Finds Its Way into Toilets

Sustainability in toilet designTechnology and design influence how things are built and engineered, including toilets. You can see the latest designs at the Toto Museum in Japan and the Sulabh International Museum of Toilets in India.

Many countries, such as New Zealand, are now focusing on creating a green and sustainable sanitation system.  All of these are designed to protect the environment.


The trend for engineering and construction companies is sustainability. It has become the guide in designing homes and planning toilet systems. This is understandable considering the enormous demands that population growth and production put on the environment.

An individual needs to use only 50 litres of water on a daily basis. In New Zealand, people use more than 80 litres a day. This is only for toilet use. Another 68 litres goes towards hygiene such as bathing.  National Geographic revealed that using the toilet also results in 27,000 trees cut down for toilet paper.

New Zealand homeowners are setting their sights on natural methods of managing human waste. These include setting up a new septic tank that relies on biological processes. It uses a natural-flow system that works well without the need for batteries.

The new septic system has an effective filtration process that separates grey and black water. Blackwater proceeds to a vermiculture machine. Greywater further undergoes different levels of filtration. The system then combines both types of wastewater and delivers it to a soil site suitable for cleansing.

Homeowners are also investing in natural materials for their bathroom. But they are not compromising style over sustainability. A good example is the adoption of marble and terrazzo. The last one especially is making a massive comeback after it became popular in the 1970s.

Terrazzo is made out of scrapped marble, rocks, cement, and even glass. These materials make it environmentally-friendly and the best choice for a sustainable house design.

For many people, being sustainable means taking care of the environment. For those who are upgrading their sanitation systems to something that is sustainable and natural, these materials help them save money and the environment.
