The higher volatile content of biomass [22], [23] may affect fluidity during the plastic phase of the cokemaking process, ultimately leading to biocokes with high coke reactivity index (CRI) and low coke strength after reaction (CSR) compared to conventional cokes [24]. The feed size also affects the mechanical properties of the biocoke.

In the hydrothermal treatment process, biochar as a solid and carbonrich product is obtained from biomass. Generally, wet biomass with lignocellulosic content is converted into a kind of coal named as biocoal, biochar, or hydrochar (Ong et al., 2020; IbarraGonzalez and Rong, 2019; Zhu et al., 2021; Maki et al., 2021 ).

Fossil fuels coal and coke represent the main source of energy in the iron and steel industry. Biomass utilization practices for iron and steel making are one promising approach for partial substitution of coal and coke to mitigate CO 2 emissions. The main opportunities for biomass application in iron and steel making can be summarized in Fig. (Jahanshahi et al., 2013; Norgate et al., 2012).

The briquetting process is the conversion of agricultural waste into uniformly shaped briquettes that are easy to use, transport, and store. The idea of briquetting is using materials that are unusable, due to a lack of density, and compressing them into a solid fuel of a convenient shape that can be burned like wood or charcoal.
