Kalliyath Group has opened its Green Core facility in Palakkad, Kerala, a key step in integrating sustainable practices into India's manufacturing sector. The plant uses advanced methods like direct hot charging, energy-efficient furnaces, and water conservation to reduce its environmental impact, showing a wider industry shift to cleaner production. However, these green steel projects must succeed in the context of India's dynamic and competitive steel market.
Kalliyath's Green Technology Focus
The ₹5 billion Green Core project introduces advanced technologies to cut environmental impact. The adoption of direct hot charging and rolling aims to cut energy use by eliminating fossil fuels, projected to save 30-50 units per tonne of steel and over 3.54 million units of electricity annually. IGBT-based voltage-fed induction furnaces are expected to further enhance power efficiency, estimating annual savings of 1.18 million units of electricity. Beyond energy, the facility's commitment to water conservation includes dry cooling systems that slash process water usage by nearly 99%, and rainwater harvesting, addressing crucial resource management, especially water scarcity. The project also plans a sub-surface dyke to manage groundwater, potentially saving around 1.87 lakh kilolitres of water annually. The project is expected to create over 1,000 jobs, boosting local economies. The company states the project aligns with national priorities for sustainable manufacturing, using recycled steel as a main raw material.
Indian Steel Market: Growth and Pressures
The Indian steel sector, key to the nation's economic growth, is seeing strong demand, forecast to grow about 9-10% in FY2026. India's crude steel output is high, with capacity expected to reach 260-280 million tonnes by 2035. This expansion comes amid significant market pressures. Higher supply has led to a temporary surplus, pressuring steel prices. Domestic hot-rolled coil (HRC) prices averaged around ₹50,500 per tonne in FY2026. Operating margins are forecast to stay around 12.5%, reflecting these lower prices.
Major players are also investing heavily in sustainability. JSW Steel (market cap near ₹3.01tn, P/E ~38.33) aims for carbon neutrality by 2050 and is developing green hydrogen plants. Tata Steel (valued over ₹2.37tn, P/E ~27.59) aims for net-zero emissions by 2045, piloting hydrogen steelmaking and using renewable energy. SAIL (market cap ~₹62,938 Cr, P/E ~25.76) is also piloting hydrogen blending. Kalliyath's project focuses on specific efficiencies, while these larger players integrate green strategies across their much larger operations. The entire Indian steel industry is preparing for this transition, guided by a Green Steel Taxonomy to help with low-carbon operations and climate finance.
Challenges and Costs of Green Steel
Despite its sustainability focus, Kalliyath's project faces significant industry challenges. The ₹5 billion investment for this facility shows the high capital costs of green steel, which can hinder widespread adoption. Many steelmakers are adding capacity using traditional methods (BF-BOF), risking future carbon-intensive asset lock-in. The extra cost for green steel, estimated at $210 per tonne for carbon-neutral production, is a major hurdle, especially when traditional steel prices are low. The sector is also sensitive to raw material price swings and global oversupply, worsened by high exports from countries like China. While Kalliyath's project boosts efficiency, its long-term success relies on achieving scale, getting premium prices, and navigating the competitive market where larger players have more financial power for decarbonization.
The Future of Green Steel in India
India's steel industry is increasingly tied to sustainability requirements. Demand for green steel, though new, is projected to reach 4.49 million tonnes by FY2030, mainly from construction and infrastructure. This demand, along with government support and frameworks like the Green Steel Taxonomy, should drive significant investment in decarbonization. The sector's projected 9% annual growth requires substantial investment, estimated at over $156 billion by 2030-31 to reach a 300 million tonnes per year capacity target. As the industry transforms, the success of projects like Kalliyath's Green Core will show how well the sector can balance growth with sustainability and profitability.
