Biochar is an ample source of organic carbon prepared by the thermal breakdown of biomass. Lignocellulosic biomass is a promising precursor for biochar production, and has several applications in various industries. In addition, biochar can be applied for environmental revitalization by reducing the negative impacts through intrinsic mechanisms. In addition to its environmentally friendly nature, biochar has several recyclable and inexpensive benefits. Nourishing and detoxification of the environment can be undertaken using biochar by different investigators on account of its excellent contaminant removal capacity. Studies have shown that biochar can be improved by activation to remove toxic pollutants. In general, biochar is produced by closed-loop systems; however, decentralized methods have been proven to be more efficient for increasing resource efficiency in view of circular bio-economy and lignocellulosic waste management. In the last decade, several studies have been conducted to reveal the unexplored potential and to understand the knowledge gaps in different biochar-based applications. However, there is still a crucial need for research to acquire sufficient data regarding biochar modification and management, the utilization of lignocellulosic biomass, and achieving a sustainable paradigm. The present review has been articulated to provide a summary of information on different aspects of biochar, such as production, characterization, modification for improvisation, issues, and remediation have been addressed.
生物炭是一种丰富的有机碳源，由生物质的热解制备而成。木质纤维素生物质是生产生物炭的有前途的前体，在各个行业中有多种应用。此外，生物炭还可以通过内在机制减少负面影响，应用于环境振兴。除了环保性质外，生物炭还有一些可回收和廉价的优点。不同的研究人员可以使用生物炭进行环境的滋养和解毒，因为它具有出色的污染物去除能力。研究表明，生物炭可以通过活化来提高去除有毒污染物的能力。总的来说，生物炭是通过闭环系统生产的；然而，鉴于循环生物经济和木质纤维素废物管理，分散方法已被证明在提高资源效率方面更有效。在过去的十年中，已经进行了几项研究来揭示生物炭在不同应用中的未开发潜力和理解知识空白。然而，仍然需要进行研究，以获取有关生物炭改性和管理、木质纤维素生物质利用以及实现可持续范式的充分数据。本综述旨在提供有关生物炭生产、特性、改良、问题和修复等不同方面的信息摘要。
