Iron and steel production has been going on in India since ancient times, which is demonstrated by important historical structures, such as the iron beam in Orissa’s famous Konark Temple and the 7 meters tall iron pillar close to Delhi’s Qutub Minar. In modern times, the Indian steel industry is essential for infrastructure development and the country’s GDP. In terms of steel production, India holds 5th position in the world and the industry is a fast developing one.
A key concern of our times is developing sustainable production and consumption practices. In this regard, the global steel industry is taking several initiates to ensure resource efficiency and promote innovation. Stats indicate that above 90% of raw materials used in the steel industry are converted to valuable materials. Even the co-products of the steel industry are utilized, some within the same industry and some in different industries.
Below are some common applications of co-products of steel industry:
Blast furnace slag: This is a popular substitute for clinker in the production of cement.
Steelmaking slag: This slag is very useful in the agricultural sector where it is employed to improve soil quality. It is also used in road construction to form aggregates.
Process gases: Process gases have two very important uses. They are utilized in the production of heat and electricity. These gases also have the potential to be changed into fuel that can be utilized for aircrafts and other forms of transport.
Dust and sludge: These are helpful substances in internal and external processes where iron oxides and alloying elements are used.
Petrochemicals from cokemaking: Petrochemicals generated from the cokemaking industry include ammonia, tar, phenol, naphthalene and sulphuric acid, which serve many purposes in the chemical industry.
Used oil and emulsions from mills: These serve as reducing agents in blast furnaces or are utilized in coke plants.
Ongoing technological developments are aimed at manufacturing co-products with improved properties; thereby further increasing the usage rates of these substances.
How Steel is contributing to a Sustainable World
The durability of steel is fueling creativity in a variety of fields. One example is the mobile canning concept developed to help farmers preserve their yield. This facility could help farmers earn higher profits by generating ready-for-market canned goods and also drastically reduce crop wastage.
The steel industry is also playing a key role in the shift towards renewable energy. Honestly speaking, without the steel industry renewable energy would be unworkable. Some of the most important innovations in the sustainable energy sector have happened because of steel. For example: China’s mega solar power scheme, South Korea’s tidal energy infrastructure and the floating wind farm off the shores of Scotland, which is the first of its kind in the world.
