Arsenic contamination in water remains a serious public health challenge in many parts of the world, especially in regions where groundwater is widely used for drinking and irrigation. A study published in Biochar reports an eco-friendly adsorbent made from biochar and laterite minerals that can efficiently remove both major forms of arsenic from water while remaining regenerable and safe for disposal.

A review highlights how modified biochar can capture and break down humic acid, a key precursor of harmful disinfection byproducts in drinking water treatment

A global analysis of field experiments suggests that biochar, a carbon-rich material made by heating organic biomass with limited oxygen, can significantly increase soil microbial biomass carbon, an important indicator of soil health and biological activity.

A plant best known as an ecological problem may offer a new tool for healthier soils and more resilient crops. A study published in Biochar reports that biochar made from Solidago canadensis L., an invasive plant in southern China, can be modified with silicon to suppress bacterial wilt, improve soil quality, and promote beneficial soil microbes.

A study reveals how cottonseed waste can be transformed into clean energy, offering a promising path toward a self-sustaining and fossil fuel-free cotton industry.

Heavy metal pollution from mining and industrial activities continues to threaten soils, ecosystems, and human health worldwide. Contaminants such as lead and zinc can persist in soils for decades, entering the food chain and posing serious risks. A study offers a promising, nature-based solution by combining biochar with a carefully designed community of beneficial microorganisms to enhance plant-driven cleanup of polluted soils.
