Steel scrap recycling is the process of converting discarded steel into new products through a series of processes that involve sorting, shredding, melting, refining, and production. In India, steel scrap recycling is becoming an increasingly important industry as it helps conserve natural resources, reduce greenhouse gas emissions, and create economic opportunities. This article provides an overview of the steel scrap recycling industry in India, including the types of plants, companies, business processes, and benefits of recycling steel scrap.
Overview of steel scrap recycling plants in India
India has three types of steel plants that are involved in steel scrap recycling: integrated steel plants, mini steel plants, and scrap-based steel plants.
- Integrated steel plants are large-scale facilities that produce steel from iron ore, using blast furnaces and converters.
- Mini steel plants, on the other hand, use electric arc furnaces to produce steel from scrap.
- Scrap-based steel plants are facilities that produce steel entirely from scrap, without using any iron ore.
The location of steel scrap recycling plants in India varies depending on the type of plant. Integrated steel plants are usually located near sources of iron ore and coal. While mini steel plants are located in urban areas where there is a high demand for steel products. Scrap-based steel plants are typically located near cities and towns, where there is a steady supply of scrap.
The capacity of steel scrap recycling plants in India also varies depending on the type of plant. Integrated steel plants have the highest capacity. And some plants are even capable of producing millions of tonnes of steel per year. Mini steel plants have a lower capacity, typically producing hundreds of thousands of tonnes of steel per year. Scrap-based steel plants have the lowest capacity, producing tens of thousands of tonnes of steel per year.
Companies in the steel scrap recycling industry in India
India has several major players in the steel scrap recycling industry, including Tata Steel, JSW Steel, and Essar Steel.
- Tata Steel is the largest steel producer in India, with a capacity of over 30 million tonnes per year and has several integrated steel plants across the country.
- JSW Steel is another major player in the industry, with a capacity of over 18 million tonnes per year and has both integrated and mini steel plants.
- Essar Steel, now known as ArcelorMittal Nippon Steel India, is a joint venture between ArcelorMittal and Nippon Steel and has several integrated and mini steel plants.
Other players in the steel scrap recycling industry in India include Steel Authority of India Limited (SAIL), Jindal Steel and Power Limited (JSPL), and Bhushan Steel. These companies also have several integrated and mini steel plants across the country.
Business processes in steel scrap recycling industry in India
The business processes in the steel scrap recycling industry in India involve several stages, including:
- The collection of steel scrap in India is done through several channels, including scrap dealers, waste pickers, and informal recyclers. The scrap is then sorted and graded based on its quality and composition. This is a crucial stage as the quality of the scrap determines the quality of the steel produced.
- The processing of steel scrap involves shredding the scrap into small pieces using machines. The shredded scrap is then melted in electric arc furnaces or blast furnaces, depending on the type of plant. In the melting stage, the impurities in the scrap are removed through slagging, and alloying elements are added to produce the desired steel composition. The steel is then refined to improve its quality and cast into various shapes.
- The production stage involves the manufacture of various steel products, including bars, rods, pipes, and sheets, among others. These products are then sold to customers, including construction companies, automobile manufacturers, and others.
Benefits of steel scrap recycling in India
There are several benefits of steel scrap recycling in India, including environmental, economic, and social benefits.
- Environmental benefits of steel scrap recycling include the reduction of greenhouse gas emissions. The production of steel from virgin materials requires a lot of energy and emits a significant amount of carbon dioxide. And recycling steel scrap reduces the need for virgin materials and energy, leading to a reduction in greenhouse gas emissions. Further, it also conserves natural resources by reducing the demand for iron ore and coal.
- Economic benefits of steel scrap recycling include cost savings. The use of steel scrap in the production of steel is cheaper than using virgin materials, resulting in cost savings for steel producers. Moreover, it also creates job opportunities in the collection, sorting, and processing of scrap. The steel scrap recycling industry also contributes to the growth of local economies. As it provides a market for scrap collectors and creates demand for related services.
- Social benefits of steel scrap recycling include improved public health. It reduces the amount of waste that ends up in landfills, leading to a reduction in the pollution of air, water, and soil. Furthermore, it also reduces the incidence of crime, as it provides an alternative source of income for people who might otherwise engage in illegal activities.
Challenges of steel scrap recycling in India
Despite the benefits of steel scrap recycling in India, the industry faces several challenges. These are:
- One of the biggest challenges is the lack of proper collection and segregation infrastructure. Many of the scrap collectors in India are informal, and the scrap they collect is often contaminated with other materials, making it difficult to recycle. There is also a low level of awareness among the public regarding the importance of recycling steel scrap.
- Another challenge facing the steel scrap recycling industry in India is the lack of government regulations and policies. The industry is largely unregulated, which has led to illegal activities such as the theft of steel scrap. The government needs to implement policies and regulations to promote the recycling of steel scrap and discourage illegal activities.
Future of steel scrap recycling in India
Despite the challenges, the future of steel scrap recycling in India looks promising. The government has recognised the importance of recycling and has taken several steps to promote it. For example, the government has launched the Swachh Bharat Abhiyan (Clean India Mission) and the National Clean Energy Fund to promote waste management and clean energy. The government has also introduced the Steel Scrap Recycling Policy, which aims to increase the recycling of steel scrap and reduce the country’s dependence on imported scrap.
The Steel Scrap Recycling Policy, launched in 2019, aims to achieve a target of 70% recycling of steel scrap by 2030. The policy includes several measures such as the establishment of recycling clusters, the development of scrap parks, and the introduction of a scrap-based steel production route. The policy also aims to promote the use of domestically produced steel scrap in government projects, which will create demand for the scrap and promote its recycling.
