They consists of [four-liter pouches](https://www.trendhunter.com/trends/portable-water-filtration-system) that harness the Sun's energy to remove more than 99.9 percent of pathogenic bacteria in water. The biggest benefit of SolarSacks is their cost efficiency. Each sack costs less than 25 cents to produce, and they only get marked up to about one dollar per sack for the end consumer (presumably aid organizations and local governments.) That markup accounts for the cost of distribution — the Danish students behind SolarSacks will not take any profit from the endeavor. Further, since [sunlight is free and abundant](https://www.trendhunter.com/trends/oakham-sun-city) in Kenya and Uganda, the two countries where the product has undergone trials, there is no cost to power them. ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 34% | Activity: 39% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Gen Alpha, Millennial, Gen X - Top markets: Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Social Good](https://www.trendhunter.com/socialgood) > [Charity](https://www.trendhunter.com/charity) ## Key Themes ### What Makes This Trend Stand Out - **Solar-powered Water Purification:** SolarSacks harness solar energy to purify water, providing a cost-effective and sustainable solution for low-income areas with limited access to clean water. - **Low-cost Water Purification:** SolarSacks offer an affordable method for removing pathogenic bacteria from water, making them accessible to aid organizations and local governments in impoverished regions. - **Environmentally Friendly Water Treatment:** SolarSacks utilize sunlight as a renewable energy source, minimizing the environmental impact of water purification processes. ### Sectors Adopting This - **Water Purification:** The water purification industry can incorporate solar-powered technology, such as SolarSacks, to enhance their products and services, expanding their reach to underserved communities. - **Aid Organizations:** SolarSacks present an opportunity for aid organizations to provide affordable and sustainable water purification solutions to low-income areas, improving public health and well-being. - **Renewable Energy:** The renewable energy industry can explore innovative applications of solar power, like SolarSacks, to diversify their offerings and contribute to addressing global water scarcity issues. ## Related on Trend Hunter - [Tire-Crafted Solar Stills](https://www.trendhunter.com/trends/floating-solar-still.md) - [Multifaceted Water Filtration Kits](https://www.trendhunter.com/trends/water-filtration-kit.md) - [Stackable Electricity-Free Water Filters](https://www.trendhunter.com/trends/electricityfree-water-filter.md) - [Solar-Powered Pool Sanitizers](https://www.trendhunter.com/trends/solar-pool-ionizer.md) - [Personal Water Purifiers](https://www.trendhunter.com/trends/lifestraw-mission.md) - [Oceanic Pressure Water Purifiers](https://www.trendhunter.com/trends/quenchsea-reel.md) - [Portable Water Filtration Systems](https://www.trendhunter.com/trends/portable-water-filtration-system.md) - [Low-Cost Water Purifiers](https://www.trendhunter.com/trends/edrop-water-purifier.md) - [Miniature Water Filtration Straws](https://www.trendhunter.com/trends/peak-solo.md)
