Current Affair 1:

Steel slag road technology

 

The technology has been developed by the Central Road Research Institute under a research project in collaboration with the Ministry of Steel, Government of India and four major steel manufacturing companies of the country, viz., ArcelorMittal Nippon Steel, JSW Steel, Tata Steel and Rashtriya Ispat Nigam.

India is the second largest steel producing country in the world and about 19 million tonnes of steel slag is generated in the country as a solid waste, which will increase to 60 million tonnes by the year 2030. (About 200 kg of steel slag is generated in one tonne of steel production).   Due to non-availability of efficient disposal methods of steel slag, huge piles of steel slag have come up around the steel plants, which have become a major source of water, air and land pollution

 

What needs to be solution?

Steel slag Valorisation as road making aggregates can provide an attractive alternate to steel industries for its safe, productive utilization in road construction.  CSIR-CRRI under the major research project sponsored by Ministry of Steel has developed the steel slag valorisation technology for conversion of steel slag as road making aggregates.  Processed steel slag aggregates developed through steel slag valorisation at AMNS India steel plant at Hazira have been successfully utilized in the construction of one km long six lane bituminous steel slag road connecting NH-6 to Hazira port at Surat, Gujarat.

Types of Steel Slag:

Steel making slag can be broadly classified in two categories based on steelmaking processes.

1. The first is the Basic-Oxygen-Furnace (BOF) steelmaking process through which hot metal received from blast furnace is converted to steel.
2. The second is the Electric-Arc Furnace (EAF) steelmaking process, which recycles mainly steel scraps.

Good manufacturing practice (GMP): WHO Certification

 

Good Manufacturing Practices (GMP, also referred to as 'cGMP' or 'current Good Manufacturing Practice') is the aspect of quality assurance that ensures that medicinal products are consistently produced and controlled to the quality standards appropriate to their intended use and as required by the product specification.

GMP defines quality measures for both production and quality control and defines general measures to ensure that processes necessary for production and testing are clearly defined, validated, reviewed, and documented.

GMP also has legal components, covering responsibilities for distribution, contract manufacturing and testing, and responses to product defects and complaints.
