The Iron and Steel Industry is, without a doubt, one of the most important foundations of any industrial economy. However, the industry also significantly contributes to environmental pollution. It, therefore, needs to adopt more efficient and cleaner technologies to minimize environmental pollution and ensure the long term sustainability of industry.
Few years back, China started asking for supplies of mill scale, which is a milling waste generated while rolling the metal in metal excursion industries. Steel rolling mills took note of this. Something that was earlier thrown out as waste was being bought in whatever quantity available. Thus, the talk of mill scale circulated. Some governments, like India and Turkey, also took note of this development and they stopped exporting this so-called waste material.
Jammu-based entrepreneur and founder of Green Trek Research & Development, Sandeep Gupta, is working in the field of waste management which focuses on green technology to develop and manufacture its products. Incubated by IIT Mandi Catalyst, it focuses on spreading the use of this process to other geographical areas as well.
The company’s core area is recycling different types of steel waste such as Oxides and Metallic Scrap. The process uses steel waste as its raw material to recover clean metal having an iron content of 99%+ , which is then poured into molds for the manufacture of different types of steel and alloy castings. Instead it uses up mounds of mill scale and steel scrap that surround steel mills in our countryside and supplies these spares to industries such as stone crushers, cement plants, power plants, oil & gas plants, defence and other industries.
The process does not need any electric power. Hence it can be used in places where power availability is nil or scarce. It has a very strong impact on the environment as it does not create pollution by minimizing the carbon footprints emitted into the atmosphere by more than 95%.
The economic feasibility of the process is very attractive. It does not require a costly plant or equipment. It is an exceptionally clean process and causes no pollution to the environment. It leaves no residue. Also the size of a steel foundry using this process can vary from 100Mt/month to 200Mt/month.
The company’s trade and scope of impact is not limited to national borders but also globally. Green Trek works on a Circular Economy model by utilizing technology for a sustainable waste management process.
Recycle, Reuse, Reduce and Redesign, according to Sandeep Gupta, are the 4R’s the company works upon. “What is important is not being big, but smart and innovative”, he says.
Some of the benefits of recycling metal are as follows- minimising dependency on our natural resources, preservation of natural resources, improvement in air quality and groundwater, reduction of emissions, economic development etc.
To conclude, metal is an essential resource which should be recycled to ensure a steady supply, prevent environmental degradation and improve the economy.
