Carbon Reduction Manufacturing

We Are a Vital Link in the Global Clean Energy Supply Chain

The majority of Iraeta's products are used across clean energy sectors such as wind, hydro, solar thermal, and nuclear power. As a key contributor to the global clean energy supply chain, we are deeply committed to lowering our own carbon footprint. In addition to using short-process steel as our primary raw material, we’ve adopted a range of low-carbon manufacturing solutions throughout our operations. These include hot charging of billets, oxy-fuel combustion, metal construction techniques, and near-net-shape forming.

Cutting Carbon with Advanced Manufacturing

Construction Molding

Construction Molding Technology uses small homogenized metal slabs as basic units. Through surface activation, vacuum sealing and hot forming, bonding interfaces match the base material perfectly to produce uniform blanks for large forgings — realizing “manufacturing big parts from small pieces”. Free of runners and risers found on traditional ingots, these composite slabs greatly raise material utilization and reduce carbon footprint.

Near-Net-Shape Forming

Near-net shape forming technology adopts specialized design to ensure the hot-worked dimensions of forgings match the finished part dimensions as closely as possible. This reduces the weight of raw stock and cuts machining allowances, which in turn lowers the product’s carbon footprint.

What's Low-emission Steel

Comprehensive Waste Management

Safeguarding the Atmosphere

We strictly comply with all applicable environmental regulations, employing advanced systems such as SCR denitrification, pulse-jet baghouse filters, and continuous emissions monitoring (CEMS) to ensure rigorous control of exhaust treatment and full compliance with emission standards.

Maximizing Waste Recycling

We have implemented a comprehensive recycling process for steel scrap and residual materials generated during production, aiming to recover valuable raw materials and achieve both environmental sustainability and resource efficiency.

Cutting Carbon in Energy Use

Oxy-Fuel Combustion

Ambient air contains approximately 21% oxygen. Our oxy-fuel combustion technology increases oxygen concentration, improving furnace efficiency while reducing NOx emissions.

Rooftop Photovoltaic Systems

We've installed rooftop solar across our main facilities, generating over 20 million kWh annually. This fully covers all our office and HVAC electricity needs, as well as a portion of our production power requirements.
