Biomass residues an alternative for fossil fuels in Metal Production

Date:8 Feb 2022

Application

• CO2 Emission Reduction: Biomass-based materials like bio-coke, bio-sinter, and bio-briquettes can replace fossil fuels in steel and iron production, lowering CO2 emissions.
• Sustainable Steel Production: Biomass helps reduce reliance on fossil carbon, supporting more sustainable and eco-friendly manufacturing processes in the steel industry.

Description

This project investigates the use of renewable biomass as an alternative to fossil fuels in iron and steel production to reduce CO2 emissions. The study explores various biomass applications, including bio-coke, bio-sinter, and bio-briquettes, for replacing traditional materials like coke and coal. It highlights the potential of biomass to lower CO2 emissions by up to 12% in steel production. The research emphasizes the need for innovative approaches to replace fossil carbon with renewable, neutral carbon sources in the short to medium term.

Pathway Description:

The process involves blending biomass with coal to create bio-coke, used in the blast furnace. Biomass is also converted into bio-sinter and bio-briquettes, replacing coke and reducing CO2 emissions. Additionally, biomass products like pyrolyzed charcoal are injected into the blast furnace to further reduce coal consumption. These innovations help lower CO2 emissions and improve energy efficiency in steel production.
