Asia-Pacific Partnership on Clean Development and Climate

The state–of-the-art clean technologies (SOACT) for steelmaking handbook

Steel is used in many aspects of our lives, in such diverse applications as buildings, bridges, automobiles and trucks, food containers, and medical devices, to name a few.  Steel provides substantial direct employment in the Asia-Pacific Partnership on Clean Development and Climate (APP) countries, and provides a significant direct contribution to the APP economies. Countless additional jobs and economic benefits are provided in steel industry supply and support activities, including mining, capital equipment supply, utilities and many community industries.

The aggregate carbon dioxide (CO2) emissions from the global steel industry have reached roughly two billion tons annually, accounting for approximately 5% of global anthropogenic CO2 emissions. Countries in the APP account for more than 57% of global steel production. The APP Steel Task Force, therefore, has significant potential to reduce CO2 emissions and conserve energy by sharing information on clean technologies, and by cooperating to implement such technologies. To enable these efforts, the Partnership will emphasize public–private cooperation to reduce or
remove barriers to technology implementation.

The production process for manufacturing steel is energy-intensive and requires a large amount of natural resources. Energy constitutes a significant portion of the cost of steel production, up to 40% in some countries. Thus, increasing energy efficiency is the most cost-effective way to improve the environmental performance of this industry.

To address these issues, there has been significant investment in new products, plants, technologies and operating practices.  The result has been a dramatic improvement in the performance of steel products, and a related reduction in the consumption of energy and raw materials in their manufacture. Recent developments have enabled the steel industry’s customers to improve their products through better corrosion resistance, reduced weight and improved energy performance. This improvement is seen through a wide range of products, including passenger cars, packaging and construction materials.
