The process, known as BioIron™, uses raw biomass instead of metallurgical coal as a reductant and microwave energy to convert Pilbara iron ore to metallic iron in the steelmaking process. BioIron™ has the potential to support nearzero CO 2 steelmaking, and can result in net negative emissions if linked with carbon capture and storage.
: Changes to Iron Production. Technological advancements in metallurgy, most notably smelting with coal or coke, increased the supply and decreased the price of iron, aiding a number of industries and making iron common in the rapidly growing machinery and engine sectors.
substitute for coal in most applications and in boilers. Briquettes can be produced with a density o f g/cm³ from loose biomass of bulk density to g/cm³ These can be burnt clean and therefore are ecofriendly arid also those advantages that are associated with the use of biomass are present in the briquettes.
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 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.

Topcharging of biocoal directly to the blast furnace is difficult due to its low strength but can be facilitated if biocoal is added as an ingredient in coke or to the mix when producing residue briquettes.
Biocoal is produced by processing dry biomass in an inert environment (no oxygen) at high temperatures, a process referred to as pyrolysis. Depending on the temperatures and the characteristics of the end product, the process may also be referred to as torrefaction. This process is commonly carried out using an indirectfired rotary kiln.
