Engineering conversion of Asteraceae plants into biochars for exploring potential applications: A review

Asteraceae presents one of the most globally prevalent, cultivated, and fundamental plant families. However, a large amount of agricultural wastes has been yearly released from Asteraceae crops, causing adverse impacts on the environment. The objective of this work is to have insights into their biomass potentials and technical possibility of conversion into biochars. Physicochemical properties are systematically articulated to orientate environmental application, soil amendment, and other utilizations. Utilizations of Asteraceae biochars in wastewater treatment can be categorized by heavy metal ions, organic dyes, antibiotics, persistent organic pollutants (POPs), and explosive compounds. Some efforts were made to analyze the production cost, as well as the challenges and prospects of Asteraceae-based biochars. (c) 2021 Elsevier B.V. All rights reserved.

Automated summary

Asteraceae is one of the most globally prevalent and cultivated plant families, but the agricultural wastes from these crops have adverse impacts on the environment. This study aims to explore the biomass potentials of Asteraceae and their conversion into biochars, as well as the utilization of Asteraceae biochars in wastewater treatment. Efforts were made to analyze production costs and discuss the challenges and prospects of Asteraceae-based biochars.
