Context: The steel industry contributes 8% of global CO2 emissions. Decarbonization efforts have spurred innovations in green steel using renewable energy and sustainable practices.
About Green Steel:
• What It Is: Green steel refers to steel produced using renewable energy and sustainable processes, minimizing carbon emissions.
• Green steel refers to steel produced using renewable energy and sustainable processes, minimizing carbon emissions.
• Various Methods in Prodcution: Electric Arc Furnaces (EAF): Use renewable electricity to melt scrap metal, significantly reducing CO2 emissions. Green Hydrogen-Based Reduction: Replaces coal with hydrogen derived from renewable sources to process iron ore. Direct Electrolysis: A method similar to aluminium production, using renewable electricity to extract iron from ore (e.g., Boston Metal’s innovation). Dismantled ships scrap: Green steel is also made using ferrous scrap mix in the raw material chain to ensure a proportionate reduction in carbon dioxide emissions.

• Dismantled ships scrap: Green steel is also made using ferrous scrap mix in the raw material chain to ensure a proportionate reduction in carbon dioxide emissions.
• Significance: Environmental Benefits: Reduces dependence on fossil fuels, cutting up to 75% of CO2 emissions in some methods. Circular Economy: Promotes recycling of ferrous scrap from end-of-life products like ships and vehicles. Economic Potential: Creates demand for renewable energy and green hydrogen, driving innovation and job creation in decarbonization technologies. Global Climate Goals: Aligns with initiatives like SteelZero, aiming for zero-emission steel by 2050.

Hong Kong Convention:
· What It Is: The Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships was adopted in June 2009 to regulate ship dismantling practices globally.
· Aim: Ensure safe, environmentally sound ship recycling and protect worker health.
· Timeline: Takes effect globally in June 2025 after ratification.
· India’s Status: Ratified by India; 50% of Alang yards are compliant.
· Limitations: Allows the “beaching” method and focuses on safety standards, not eliminating harmful practices.
