Drastic change in the climate is the biggest problem for the entire steel industry in the 21st century. Lessening CO2 emissions in steelmaking must be overcome on a global level. Making the substantial CO2 diminutions needed will require technology transfer, collaboration and advance technologies.
The lessening of CO2 from steel production is a recognised priority, as is the decrement of GHG emissions during the life cycle of products that utilise steel. Our member organizations include tactics into their businesses to enhance processes and drive product innovation in this direction.
In order to radically diminish the entire CO2 emissions from the fabrication of steel, the development of advance technologies is necessary. Nowadays, a large number of encouraging projects are ongoing in dissimilar zones of the world. Some projects are in the initial research level while others are in pilot or demonstration level. Although their objectives are same, strategies vary and can be categorised as follows:
Hydrogen as a plummeting agent – Evades carbon and utilises hydrogen to lessen iron ore thereby preventing the formation of CO2, and generating H2O (water).
Carbon Detention and Storage (CCS) – Produces a clean and concentrated CO2 stream that can be seized and stowed. The process incorporates retrofitting steel plants with capture technology and needs the emergence of transportation networks and access to storage sites.
Carbon Capture and Usage (CCU) – Utilises the elements of the co-product gases from present processes to generate fuels or input material for the chemical industry.
Biomass as a lessening agent – Can partly replace coal for biomass such as charcoal.
Electrolysis – Lessens iron ore via utilising electricity.
Every technology plays an essential role in lessening CO2 emissions. Their execution at a larger scale, however, will need enormous quantities of carbon-free hydrogen, biomass and electricity to be willingly available, which executes an important conversion of the global energy system.
Effectual utilisation of resources, re-use and salvaging, are also necessary for sustainable development. Material efficiency is an essential part of the today’s steelmaking process. Our motive is to utilise all raw materials to their fullest, guaranteeing zero waste from steelmaking. This ambition assurances that almost every by-product generated during steelmaking is utilised in the formation of new products. This method curtails the amount of waste dumped to landfill, lessens emissions, and conserves raw materials.
Environmental sustainability is also associated to the development of new and sturdier products, which in the long-term will offer clear and lasting positive merits for the environment.
For the steel industry, the effect of steel during the whole life cycle of products, the usage of by-products, salvaging, energy and water management are imperative key areas. Another approach that is used to minimise emission of CO2 is the efficient utilisation of energy.
It’s no longer a doubt that today’s air-quality is worse than ever. Even those who don’t smoke are struggling with respiratory and other fatal health problems. Steel industry are putting their best efforts to lessen the production and emission of toxic gases.
