This review focuses on a holistic view of biochar, production from feedstock's, engineering production strategies, its applications and future prospects. This article reveals a systematic emphasis on the continuation and development of biochar and its production methods such as Physical engineering, chemical and bio-engineering techniques. In addition, biochar alternatives such as nutrient formations and surface area made it a promising cheap source of carbon-based products such as anaerobic digestion, gasification, and pyrolysis, commercially available wastewater treatment, carbons, energy storage, microbial fuel cell electrodes, and super-capacitors repair have been reviewed. This paper also covers the knowledge blanks of strategies and ideas for the future in the field of engineering biochar production techniques and application as well as expand the technology used in the circular bio-economy.
本文综述了生物炭的整体研究进展，包括生物炭的原材料、制备工程策略、应用和未来展望。本文系统地强调了生物炭及其制备方法（物理工程、化学和生物工程技术）的延续和发展。此外，生物炭的替代物如营养成分和表面积，使生物炭成为一种有前途的、廉价的碳基产品来源，如厌氧消化、气化和热解、商业上可用的废水处理、碳、储能、微生物燃料电池电极和超级电容器修复等。本文还涵盖了工程生物炭生产技术及应用领域未来战略和思路的知识空白，拓展了循环生物经济中应用的技术。
