The role of biochar in combating microplastic pollution: a bibliometric analysis in environmental contexts
This bibliometric review used network analysis to map the growing body of research on biochar — a charcoal-like material made from burned organic matter — as a tool for countering microplastic contamination in soils and water. Studies reviewed suggest that biochar can restore soil chemistry, improve microbial diversity, and boost crop yields by 30–81% even when microplastic contamination is high. The findings highlight biochar as a practical, low-cost intervention for farmers dealing with microplastic-polluted land.
