Biochar application for environmental management and toxic pollutant remediation

Utilizing of biochar as an amendment for environmental management has been a catalyst for the recent global enthusiasm for advancing biochar production technology and its management. While both research and development of biochar for environmental management at a global scale are a somewhat recent development, it is by no means new in certain regions and has even been the subject of scientific research for quite some time. This article deals with both positive and negative impacts of biochar application for environmental management and toxic pollutant remediation by collecting exponentially increased number of publications and summarizes it to explain that how biochar can enhance in greenhouse gasses (GHGs) emission reduction, wastewater reuse, fertilizer pollution minimizing, mineral nutrients leaching reduction, and land degradation with soil erosion management. It also provides new insights into the state-of-the-art accomplishments of biochar's potential on the removal of heavy metal, toxic pollutant, and renewable energy generation was also considered. Biochar can significantly be used to trim down the leachability and bioavailability of different organic toxic pollutants via sorption mechanism. Increasing the carbon sink in soil through biochar application can help to reduce the amounts of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emission in environment. The future researches should focus on the long-term environmental fate of organic pollutant sorbed on biochar.
