Algae can clean sewage without electricity or chemicals. I posted it for a South Africa test
Credit: Pixabay/CC0 Public Domain Across Africa, many rural communities face a growing sanitation crisis. The wastewater treatment systems in which they exist are often outdated, overloaded or broken. In some towns, untreated sewage flows directly into the river, polluting water sources and damaging both ecosystems and public health. For decades, the global response to wastewater has been to clean water…

Designing a clean energy future: 2d Janus heterobilayers lead
2D Janus Heterobilayers design for efficient water splitting. The unique Janus structure with an internal electric field enhances photocatalytic performance. The blue arrows indicate that optimised conditions for water splitting (e.g. carrier mobility, catalyst surface, etc.) can be achieved by rationally designing 2D heterobilisers like LEGOBRICS. Credit: Nguyen Tuan Hung et al. What if there was an efficient way to…

Research shows that 90% of metal contamination in Adirondack Waters will decrease 50 years after Clean Air Act
Skyfuller holds sediment core samples collected from Heartlake in the Adirondack Mountains. Credit: SkyFuller A study published by researchers at the University of Albany presented the first documented evidence that the Adirondack surface water has recovered almost completely from metal contamination since the enactment of the Clean Air Act. Originally passed in 1963 and amended in the next few decades,…

How surface current circulation patterns help clean Great Pacific garbage patches
A bird surrounded by debris from the ocean on an island in the northwest of Hawaii. Credit: Matthew Chaubin Between Hawaii and California, trash swirled with huge currents and got caught up in the infamous Texas-sized Great Pacific garbage patch. This is just one of many people found all over the world. While efforts to clear patches with the Sweeing…
