Project Summary: This Auburn University research project explores an innovative, cost-effective solution to urban stormwater pollution using biochar-entrained pervious concrete (BEPC). Biochar is a recycled byproduct from biofuel production. Pervious concrete allows water to pass through it and into the ground instead of directing stormwater into local streams. Biochar can trap harmful substances like oil, heavy metals, and nutrients so that they don't contaminate surface or groundwater. The team will pour real stormwater through BEPC samples in the lab to see how well it removes pollutants. They'll compare different amounts of biochar to find the most effective mix and estimate how long the concrete can keep working before needing replacement. The findings could lead to more affordable urban stormwater management strategies that protect water quality and reduce flooding.
