Carbon Reduction Manufacturing
We Are a Vital Link in the Global Clean Energy Supply Chain
The majority of Iraeta's products are utilized in clean energy sectors including wind power, hydropower, solar thermal, and nuclear power. As an integral part of the global clean energy industrial chain, we are committed to reducing carbon emissions in our own manufacturing processes. In addition to using short process steel as our primary raw material, we have implemented numerous low-carbon manufacturing technologies throughout production. These include hot charging of raw materials, oxy-fuel combustion, metal construction techniques, and near-net-shape forming processes.
Mature Waste Management
Protect the Atmosphere
We strictly comply with all legal and regulatory requirements, utilizing SCR denitrification systems, pulse-jet baghouse filters, and CEMS continuous emissions monitoring systems to maintain rigorous control over our exhaust gas treatment and ensure full compliance with emissions standards.
Solid Waste Management
We have established a systematic recycling process for steel scrap and residual materials generated during production to recover high-value raw materials, thereby achieving both environmental and resource efficiency goals.
Near-Net-Shape Forming
The steel required for super-sized forgings can range from several dozen to several hundred tonnes. Our near-net-shape forming technology employs specialized designs that closely mimic the final dimensions of the forged component. This significantly reduces machining allowances, thereby decreasing both raw material usage and the carbon emissions associated with heating processes. For certain products, this can reduce material consumption by up to 30% – delivering substantial savings on your procurement costs!
Construction Molding
For certain alloys exceeding 100 tons, the utilization rate of conventional steel ingots drops to around 70%. Unlike molten steel casting, our metal construction forming technology uses smaller, high-quality steel billets. Through vacuum encapsulation and high-temperature diffusion bonding processes, we achieve "building big from small" with a remarkable utilization rate of over 95%. This approach not only enhances quality but also significantly reduces carbon emissions from steelmaking and eliminates energy waste from heating non-productive materials.
We Achieve Carbon Reduction Targets Through the Use of New Energy
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
We've installed 26 MW of rooftop solar PV across our main facilities, generating over 20 million kWh annually. This covers all our office and HVAC electricity needs, plus a portion of production power requirements.
