Abstract

The engineered biochar has been extensively developed for environmental applications in the last decade, owing to its carbon-neutral and long-term persistent characteristics. Here, we addressed the advancement in production of novel engineered biochar with practical environmental remediation, and pointed out key challenges and future perspectives, based on total 28 publications in Critical Review in Environmental Science and Technology during 2017–2021. Without concerted efforts on engineered biochar-based environmental application integrating systematic research and environmental impact assessment, we are unlikely to achieve the circular economy-guided sustainable development.

摘要

由于其碳中性和长期持久的特性，工程生物炭在过去十年中已广泛用于环境应用。在这里，我们基于2017-2021年环境科学与技术批判性评论中的28 篇出版物，讨论了具有实用环境修复功能的新型工程生物炭生产的进步，并指出了关键挑战和未来前景。没有系统研究和环境影响评价相结合的工程生物炭环境应用，我们不可能实现以循环经济为导向的可持续发展。
