BSI - the UK's leading international certification organization - has just certified ISO 14064-1:2018 standard on greenhouse gas inventory for steel products of Hoa Phat Dung Quat Steel Joint Stock Company. This shows that the company always proactively applies the latest quality standards, production management, and operations to meet the increasing requirements of the market.

Hoa Phat Dung Quat Complex applies modern and closed circular production technology from G7 countries to optimize production as well as save energy and reduce greenhouse gas emissions

ISO 14064-1 is an environmental technical standard, implemented in accordance with the Government’s Decree 06/2022 on mitigating greenhouse gas emissions. It is used as a basis for calculating a business's greenhouse gas emissions. This is also one of the certifications that steel manufacturing enterprises need to achieve when exporting to world markets, especially the EU.

Therefore, from June 2023, Hoa Phat Dung Quat began contacting consulting units to prepare reports and inventory greenhouse gases, and provide operational data and related information to serve the greenhouse gas inventory for the 2022-23 period.

At the end of November 2023, the company completed the assessment of greenhouse gas inventory at its complex, fully meeting the requirements of ISO 14064-1:2018 certification on greenhouse gas inventory.

The company also completed the ISO 14067:2018 assessment related to carbon tracing on product lines in late January 2024. It is expected that in April, BSI will issue this certificate to Hoa Phat.

Hoa Phat is the largest steel producer in Southeast Asia. The group has applied modern, closed circular production technology from G7 countries to production at all iron and steel production complexes. Hoa Phat Group has carefully calculated and spent up to 30% of investment capital for environmental items. Hoa Phat's iron and steel production complexes in Hai Duong and Dung Quat apply a series of the latest technology solutions and applications to optimize production and save energy. Hoa Phat's annual electricity generation output reaches billions of kWh.

The thermal power plant of Hoa Phat Dung Quat Steel Company uses residual heat to generate electricity, helping the company be self-sufficient in about 80% of its electricity production

In 2023 alone, the total electricity generation of surplus thermal power plants in the Hoa Phat Steel Integrated Complex in Hai Duong and Dung Quat reached 2.4 billion kWh, helping Hoa Phat be self-sufficient in about 80% of its electricity for the production. Of which, Hoa Phat Dung Quat's electricity output recorded 1.96 billion kWh.

In addition to using excess heat from coke smelting to generate electricity, the complex also utilizes excess coal gas from iron and steel smelting as fuel for boilers to generate electricity. This power production technology has contributed to environmental protection, reducing CO2 emissions compared to coal-fired power generation with equivalent capacity.

Currently, Hoa Phat Group is applying five energy-saving steel production solutions.

The first solution is to recover residual heat, hot gas from coke ovens, and blast furnaces to produce electricity. Excess heat generated from the coke production process and residual gas from the iron and steel smelting process are recovered and utilized to generate electricity for their production.

Second solution is to use environmentally friendly dry coking technology to produce electricity.

Third solution is Blast Furnace Blower energy recovery turbine technology applied at Hai Duong and Dung Quat steel plants.

Fourth solution is to use residual heat to produce electricity during the ore sintering process.

The last solution is Continuous Casting - Rolling technology, taking advantage of heat from hot steel billets. After casting with a temperature of 750-900 degrees Celsius, the steel billets will be immediately transferred to the rolling line to produce finished steel products. This solution has minimized energy use, reduced production costs, and reduced CO2 emissions per ton of product.
