Chitosan-functionalized biochar reduced soil-available arsenic by 21% and arsenic in rice grains by 43%. Even after natural aging, it continued to limit arsenic uptake, support root growth, and promote Fe-mediated sequestration.🌾 #Biochar #Rice #FoodSafety 🔗: doi.org/10.1007/s427...

Hydrochar can strengthen soil while storing more carbon. In microcosm trials, stalk-derived hydrochar increased soil aggregate stability by 70–100% and SOC by 143–149%, outperforming straw and biochar. Feedstock choice helps tailor benefits. #Biochar #SoilHealth 🔗: doi.org/10.1007/s427...

Microalgae-derived biochar is giving wastewater membranes a performance boost. An amine-functionalized biochar/cellulose acetate membrane doubled flux, improved organic matter removal, achieved complete bacterial removal, and showed strong antifouling recovery. #Biochar doi.org/10.1007/s427...

Not all biochar is created equal. A new Perspective in Biochar explains the trade-off between long-term carbon stability and soil co-benefits, calling for clearer reporting and purpose-designed biochar for credible carbon markets. 🔗: doi.org/10.1007/s427...
