The toilet is designed with a dual-section form to separate liquid and solid waste from one another, which would allow it to function with no water. The toilet features a mechanical flush to be run with no electricity and shifts solid waste away to a storage section where it can be repurposed as fertilizer. The 'Sandi' toilet concept is built with accessibility in mind with the designer setting the price at $74 per unit, while still being suited for large families. The toilet would only need to be emptied of liquid waste every two days and solid waste every four days for a family of seven. ## Trend Insights (Trend Hunter) - Score: 7.0/10 - Popularity: 99% | Activity: 100% | Freshness: 12% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Modern](https://www.trendhunter.com/modern) ## Key Themes ### What's Driving This Trend - **Sustainable Toilets:** Designing toilets for those in rural and off-grid locations that are low-cost, sustainable, and maximize efficiency, while utilizing waste as fertilizer. - **Waterless Toilets:** Developing toilets that can separate liquid and solid waste, require no water for efficiency, and utilize waste for repurposing. - **Low-cost Toilet Solutions:** Creating low-cost solutions for toilets that can be accessible and suited for large families, while utilizing waste for repurposing. ### Who This Affects Most - **Sanitation:** Developing innovative sanitation solutions for those living in rural and off-grid locations in a sustainable and cost-effective manner. - **Agriculture:** Exploring ways to repurpose human waste as fertilizer in agricultural industries for sustainable farming practices. - **Environmental Sustainability:** Designing solutions that are both low-cost and sustainable for environmental and societal benefits in sanitation and waste reduction. ## Related on Trend Hunter - [Compact Portable Toilets](https://www.trendhunter.com/trends/clesana-x1-camping-toilet.md) - [Inflatable Portable Toilets](https://www.trendhunter.com/trends/airpot.md) - [Water-Free Telescoping Toilet Designs](https://www.trendhunter.com/trends/clesana-x1.md) - [Compact Portable Toilet Designs](https://www.trendhunter.com/trends/portable-toilets.md) - [Martian Toilet Prototypes](https://www.trendhunter.com/trends/martian-toilet.md) - [Enclosed Japanese Park Toilets](https://www.trendhunter.com/trends/toiletowa.md) - [Sustainable Timber-Made Toilets](https://www.trendhunter.com/trends/woodio-block-toilet.md) - [Hygienic Auto-Flushing Toilets](https://www.trendhunter.com/trends/close-the-lid-toilet.md) - [Smart Toilet Designs](https://www.trendhunter.com/trends/smart-toilets.md)
