Environmental pollutants including emerging contaminants are a growing concern worldwide. Organic wastes, such as food waste, compost, animal manure, crop residues, and sludge are generally used as feedstock. The conventional treatment methodologies (primary and secondary treatment process) do not mitigate or remove pollutants effectively. Hence, an effective, low-cost, and environmentally friendly tertiary treatment process is an urgent need. Biochar finds interesting applications in environmental processes like pollutant remediation, greenhouse gas mitigation, and wastewater treatment. Studies have shown that different types of adsorbents (biochars) like, native and engineered biochar are being used in the removal or mitigation of heavy metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, pesticides, disinfectants, polychlorinated dibenzofurans, and dibenzo-p-dioxins from contaminated sites for environmental management. The review discusses ample studieswhich can offer solutions for environmental sustenance and managementand the emerging trends and techno-economic prospectives of biochar for sustainable environmental management.
环境污染物，包括新兴污染物，是全世界日益关注的问题。有机废物，如食物垃圾、堆肥、动物粪便、农作物残渣和污泥，通常被用作原料。传统的处理方法（一级和二级处理工艺）不能有效减轻或去除污染物。因此，需要一种有效、低成本和环保的三级处理工艺。生物炭在环境过程中具有有趣的应用，如污染物修复、温室气体减排和废水处理。研究表明，不同类型的吸附剂（生物炭），如天然和工程生物炭，正被用于去除或减轻重金属、多环芳烃（PAHs）、多氯联苯、农药、消毒剂、多氯二苯并呋喃和二苯并对二恶英从污染场地的环境管理。本综述讨论了大量的研究，这些研究为环境可持续性和管理提供了解决方案，以及生物炭在可持续环境管理方面的新兴趋势和技术经济前景。
