Review of biochar production via crop residue pyrolysis: development and perspectives

Li, Y. , Gupta, R. , Zhang, Q. and You, S. (2023) Review of biochar production via crop residue pyrolysis: development and perspectives. Bioresource Technology, 369, 128423. (doi: 10.1016/j.biortech.2022.128423)

Abstract

Worldwide surge in crop residue generation has necessitated developing strategies for their sustainable disposal. Pyrolysis has been widely adopted to convert crop residue into biochar with bio-oil and gas being two co-products. The review adopts a whole system philosophy and systematically summarises up-to-date knowledge of crop residue pyrolysis processes, influential factors, and biochar applications. Essential process design tools for biochar production e.g., cost-benefit analysis, life cycle assessment, and machine learning methods are also reviewed, which has often been overlooked in prior reviews Important aspects include (a) correlating techno-economics of biochar production with crop residue compositions, (b) process operating conditions and management strategies, (c) biochar applications includes soil amendment, fuel displacement, catalytic usage, etc. (d) data-driven modelling techniques, (e) properties of biochar, and (f) climate change mitigation. Overall, the review will support the development of application-oriented process pipelines for crop residue-based biochar.
