Science and Technology Minister Dr Jitendra Singh on Wednesday flagged off a 1,600-metric tonne processed steel slag railway rack from Tata Steel’s Jamshedpur plant at Border Road Organization’s (BRO’s) ‘Project Arunank’ at Itanagar in Arunachal Pradesh.
Flagging it virtually, Singh said that with it India had entered the “era of steel roads”.
The project is being carried out by CSIR-CRRI along with Tata Steel and BRO to use processed steel slag aggregate – a by-product of steel manufacturing – in the construction of steel slag roads in strategic areas.
India is currently the world’s second largest producer of crude steel, producing 118 million tonnes of crude steel. Of this, about 20% of steel slag is generated as solid waste and its disposal is a major challenge for the steel industry. This solid waste will now be used in road construction. “This project is a perfect example of ‘waste of money’,” asserted Singh.
