Sustainability Problem: Health and water
2.4 billion people do not have access to safe and adequate sanitation. Sanitation related diseases are one of the leading of children under the age of 5. Further, access to clean and safe water is a growing concern: at least two-thirds of the world’s population lives with severe water scarcity for at least a month of every year and half of the world’s population is expected to live with water stress by 2030.
- Seva Sustainable Sanitation is a smart electro-chemical toilet that uses power from solar panels to sterilize and clarify wastewater for reuse for flushing or irrigation.
- Carbon, nitrogen, and phosphorus can be almost fully eliminated from the wastewater.
- The toilet can be used off-grid in developing nations.
- The toilet is outfitted with sensors, a smartphone maintenance guide, and smart grid technology that allows individuals and communities to repair the toilet as needed with only a screwdriver
- Communities and individuals that lack access to safe and adequate sanitation or in areas with severe water stress
- Governments of developing nations
- Develop and test maintenance system
- Finish field tests of prototypes
- Work with NGOs, governments, communities to disseminate and install toilets in areas in need
Comment on: Kelp as a fiber
- Kelp is a zero-waste fiber that could result in saving tons of materials, that do not readily decompose, from entering landfills. AlgiKnit could also reduce environmental pressure and resource degradation caused by the harvesting of raw materials that we currently use to make our clothing.
