Can #humanpoop make concrete stronger? Researchers have developed #biochar from human fecal waste and tested it as a partial replacement for cement in concrete. The study found promising improvements in compressive and flexural strength with a 5% biochar replacement, while also pointing toward a potential way to reduce cement use and manage faecal sludge waste. But is this actually ready for real-world buildings, roads, bridges and infrastructure? Not yet—more testing is needed. Watch this Sciencekaari episode to understand the science behind human waste biochar, concrete strength, sustainable construction, cement pollution and the future of eco-friendly building materials.
