Sustainable infrastructure development has gained renewed focus with the proposal to use steel slag technology for road construction in hilly and Himalayan regions. The technology aims to address recurring challenges such as frequent road damage, short construction windows, and harsh weather conditions, while also promoting waste reuse and long-term cost efficiency.
Why in News?
Union Minister of State for Science and Technology Jitendra Singh has recommended faster adoption of steel slag–based road technology, especially in Himalayan states, citing its proven benefits and limited current usage.
Steel Slag Technology and Its Relevance
- Steel slag is an industrial by-product generated during steel manufacturing. Instead of being treated as waste, it can be processed and reused in road construction.
- The technology improves road strength, durability, and resistance to water damage, making it particularly suitable for mountainous and high-rainfall regions.
- According to the Minister, areas with frequent landslides, heavy rainfall, and limited construction seasons stand to benefit the most.
- Despite successful trials, adoption remains uneven, highlighting the need for awareness and capacity building among state agencies.
Focus on Himalayan States
- Special emphasis is being placed on Himalayan states and Union Territories, where road maintenance is both costly and challenging.
- To bridge the awareness gap, workshops and training programmes are being organized for engineers and officials.
- A two-day workshop in Jammu and Kashmir is scheduled, followed by similar programmes across other regions.
- These initiatives aim to familiarise stakeholders with practical applications of steel slag technology and encourage its inclusion in routine road maintenance and construction projects.
Journey and Current Adoption Status
- Pilot trials of steel slag based road solutions began around two years ago in places such as Surat (Gujarat) and parts of the Northeast, including Arunachal Pradesh.
- Since then, the technology has been deployed in states like Karnataka, Uttar Pradesh, Assam, Gujarat, Jharkhand, and Andhra Pradesh. However, awareness remains limited even among senior engineers.
- This uneven adoption underscores the need for systematic dissemination and stronger coordination between government bodies and industry partners.
ECOFIX and Circular Economy Benefits
- A major outcome of the initiative is ECOFIX, a ready-to-use pothole repair mix developed by the CSIR-Central Road Research Institute with support from the Technology Development Board. ECOFIX uses processed steel slag and can be applied even in wet or waterlogged conditions.
- It reduces repair time, traffic disruption, and lifecycle costs while supporting the circular economy, which focuses on waste reuse and reduced dependence on natural resources.
Public Private Partnership and Future Plans
- The initiative reflects a shift toward balanced public–private partnerships.
- An agreement between the Technology Development Board and Ramuka Global Eco Work Private Limited enables commercial rollout of ECOFIX.
- Plans include setting up an iron and steel slag processing facility with a capacity of nearly two lakh tonnes per year, with commercial production expected by end-2027.
- The project is expected to support sustainable infrastructure, job creation, and resilient road networks.
