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.

生物炭在环境管理和有毒污染物治理中的应用

利用生物炭作为环境管理的一种修正,已成为最近全球对发展生物炭生产技术及其管理的热情的催化剂。虽然全球范围内用于环境管理的生物炭的研究和开发都是最近的发展,但在某些地区绝不是新事物,甚至在相当长的一段时间内一直是科学研究的主题。本文通过收集成倍增加的出版物,探讨了生物炭应用对环境管理和有毒污染物修复的正面和负面影响,并对其进行总结,以解释生物炭如何在温室气体(GHG)减排,废水再利用,肥料污染中增强作用。减少矿物质营养素的浸出,水土流失管理。它还为生物炭在去除重金属,有毒污染物和可再生能源方面的潜力的最新成就提供了新见解。生物炭可通过吸附机制显着地用于减少不同有机有毒污染物的浸出率和生物利用度。通过施用生物炭增加土壤中的碳汇,可以帮助减少二氧化碳(CO 生物炭可通过吸附机制显着地用于减少不同有机有毒污染物的浸出率和生物利用度。通过施用生物炭增加土壤中的碳汇,可以帮助减少二氧化碳(CO 生物炭可通过吸附机制显着地用于减少不同有机有毒污染物的浸出率和生物利用度。通过施用生物炭增加土壤中的碳汇,可以帮助减少二氧化碳(CO2),甲烷(CH 4)和一氧化二氮(N 2 O)在环境中的排放。未来的研究应集中于生物炭吸附有机污染物的长期环境命运。
