# Waste-Seperating Loos The 'No-Mix' Vacuum Toilet Uses Less Water By Vivian Lau | Published 2012-07-16 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/no-mix-vacuum-toilet References: [fastcoexist](http://www.fastcoexist.com/1680108/a-new-toilet-separates-your-business-so-we-can-harvest-its-energy) & [greenerideal](http://www.greenerideal.com/lifestyle/0712-toilet-reduces-water-reuses-waste/) The No-Mix Vacuum Toilet, conceived by the [Nanyang Technological University](https://www.trendhunter.com/trends/ultraviolet-food-storage) in Singapore separates the brown from the yellow on-site to conserve water and make use of energy-rich resources. More than one gallon of water is used to flush waste down the bowl when only 0.05 is needed for urine and 0.26 for feces. This means that the system in place now is extremely inefficient. By flushing according to the waste laid, water is used sparingly while the nutrients in urine can be more easily accessed to add to fertilizers and feces can be used to power electricity. Otherwise, [treating mixed waste](https://www.trendhunter.com/trends/smart-toilets) is extremely difficult. The design has been adopted by a few countries in Europe, but it will be a long while before any toilet of the sort becomes mainstream. ## Trend Insights (Trend Hunter) - Score: 2.8/10 - Popularity: 23% | Activity: 54% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Why This Trend Is Growing - **Waste-seperating Toilets:** Innovative toilets that separate waste on-site to conserve water and make use of energy-rich resources. - **Efficient Water Use:** Technologies that conserve water in buildings through more efficient methods of flushing waste. - **Sustainable Waste Management:** Systems that repurpose waste for energy or fertilizer production. ### Industries Being Reshaped - **Plumbing:** Developing new plumbing solutions for more efficient water use and separation of waste. - **Green Energy:** Utilizing energy-rich resources found in waste to create sustainable energy solutions. - **Agriculture:** Incorporating waste byproducts into fertilizer production for more sustainable farming practices. ## Related on Trend Hunter - [Sustainable Sand-Filled Toilets](https://www.trendhunter.com/trends/sandi-toilet.md) - [Water-Free Telescoping Toilet Designs](https://www.trendhunter.com/trends/clesana-x1.md) - [Anti-Splashing Bathroom Fixtures](https://www.trendhunter.com/trends/modern-urinal-design.md) - [Water-Saving Bathroom Capsules](https://www.trendhunter.com/trends/bergvattnet.md) - [Martian Toilet Prototypes](https://www.trendhunter.com/trends/martian-toilet.md) - [Compact Portable Toilets](https://www.trendhunter.com/trends/clesana-x1-camping-toilet.md) - [Hygienic Auto-Flushing Toilets](https://www.trendhunter.com/trends/close-the-lid-toilet.md) - [Compact Portable Toilet Designs](https://www.trendhunter.com/trends/portable-toilets.md) - [Closed-Loop Bathing Systems](https://www.trendhunter.com/trends/upfall-shower.md)
