The steel industry is the fifth-largest producer of carbon dioxide emissions in the world, responsible for 8% of the total global carbon dioxide emissions.
The Product
Aymium’s Metallurgical Carbon is engineered to precise chemistry and sizing to immediately work in metals production. The products are made using PEFC-certified, sustainably sourced recovered biomass and have fewer impurities than traditional coal-based metallurgical carbons.
The Solution
Aymium’s Metallurgical Carbon can immediately replace coal and coke in steel and other metals production, requiring no capital modifications for immediate use. The use of Aymium’s products also results in higher-quality steel and metallics with reduced impurities such as sulfur. The product is carbon-negative, and its use in steel production results in a net reduction of more than five tons of carbon dioxide per ton of coal replaced.
Traditional steel production using coal: Coal is heated to form coke. In a blast furnace, coal and iron ore are mixed and coke gasses remove oxygen from the iron ore. Next, in a basic oxygen furnace, coal or coke is added to produce slag and provide chemical energy. Then the molten steel is cast, rolled and finished. The net carbon dioxide release is 2.03 tons per ton of steel produced.
How Aymium’s Biocarbon is produced: Recovered wood is sustainably sourced and processed into uniform biomass. The biomass undergoes integrated thermolysis, a patented non-combustion process that converts the biomass into high-purity biocarbon and biogas. This process is environmentally friendly and uses self-generated renewable energy and recovered water.
Steel Production Using Biocarbon: Biocarbon, made from recovered wood, replaces coal and coke. In a blast furnace, biocarbon and iron ore are mixed and oxygen is removed from the iron ore. Next, in a basic oxygen furnace, biocarbon is added to produce slag and provide chemical energy. Then the molten steel is cast, rolled and finished. The net carbon dioxide reduction is 4.13 tons per ton of steel produced.
