Minimill technology drives Danieli Group’s global success in steel production

Danieli Group has brought Minimill technology to Bangladesh, signing a contract to provide Unitex Steel Mills with a state-of-the-art green steel plant. This is just one of several recent orders received by the company led by CEO Gianpietro Benedetti, including eight from the United States, three from China, one from Israel, one from Greece, two from Europe, and one from Japan. The demand for the company’s sustainable steel production solutions continues to grow, confirming its role as a global leader in sustainable steel technology.

Danieli Group’s Minimill: the latest advancements in steelmaking technology

Danieli Group has been contracted by Unitex Steel Mills to provide complete engineering, manufacturing, procurement, supply, and on-site services for a cutting-edge Minimill in the Feni district of Chittagong, Bangladesh. The plant will include state-of-the-art auxiliary systems for fumes and water treatment, as well as advanced electrical and automation technology. The Minimill will have a production capacity of 1 Mtpy, producing long products such as quenched rebars, smooth rounds, equal angles, and channels. The plant’s highly efficient 100-t Digimelter, featuring Q-One digital power feeder and ECS continuous-scrap charging and preheating systems, will enable competitive scrap melting. As the world focuses on reducing carbon emissions and transitioning towards a greener economy, the steel industry is increasingly urged to adopt sustainable production methods. In this scenario, Danieli Group is at the forefront of the movement with its advanced Minimill technology. Over the past decades, the Minimill – or MIDA for short – has emerged as one of the most sought-after plants in the steel industry, thanks to its superior quality, high efficiency, and low environmental impact. Its concept is based on Electric Arc Furnace EAF-based steelmaking complexes, providing flexibility, lean organizations, and low transportation costs for local raw-material sourcing and finished products distribution. Initially designed for plants with production capacities of 150-200,000 tpy, the designs have gradually increased in production capability to over 2.9 Mtpy, particularly for flat products. Subsequently, since 2006, the company has taken a significant step forward with the integrated Minimills, which include DRI plants, EAFs, CCMs, and rolling mills, all connected through a continuous energy-saving process and compact layout.

Reducing environmental impact while maintaining high-quality production: Danieli Group’s commitment

A significant step forward in sustainable steel production, Danieli Group’s integrated Minimills were first supplied in 2006, offering a more environmentally friendly and cost-effective alternative to traditional Blast Furnace integrated plants. The company’s Micromill takes this concept even further, offering ultra-compact design and extremely low transformation costs to produce 250-300,000 tpy of long products at an overall investment per ton typical of a 1.0-1.5 Mtpy Minimill. These “regional mills” transform local scrap into finished products for local markets, providing additional savings in transportation costs, representing a cost-effective solution for environmentally conscious companies. Today, as environmental regulations become more stringent, industrial producers need reliable partners with knowledge, experience, and commitment to ensure sustainability and competitiveness without slowing down production. Danieli Group’s continuous efforts to research and develop solutions for environmental sustainability address fume treatment and noise reduction, water treatment and consumption decrease, energy saving through emissions reduction, and solid waste treatment and recovery. This has made Danieli Group the go-to provider for sustainable steel production worldwide.
