From food waste to water: A new research shows how new biomass hydrogels could help turning discarded food and agricultural waste into a source of atmospheric water for irrigation and sustainable farming

Researchers developed new hydrogels from natural materials to capture atmospheric moisture. These innovative materials can absorb water vapor even in dry conditions. Mild heat releases the captured water, making the process energy efficient. Outdoor tests showed significant water production per kilogram of sorbent. This technology offers potential for off-grid water systems and disaster relief.
