Tung Ho Steel has consistently assumed the role of steel resource recycling and reuse, employing electric arc furnaces to manufacture formed steel and rebar products for earthquake-resistant buildings. Compared to other steel refining methods, electric arc furnace steel refining can reduce CO2 emissions by over 75%. In the course of steel refining, Tung Ho utilizes advanced secondary dust collection technology and equipment that are capable of effectively preventing the generation of dioxins, thus maintaining a healthy environment.
In order to effectively utilize water resources and prevent water pollution, the planning for each plant incorporates water pollution prevention and control facilities, with formulation of water pollution prevention, control, and management rules. In addition, ISO 14001 international environmental management system certification has been obtained. Current proactive measures mainly include: Recycling of water used in production, with repeated use to reduce the amount of source water consumed; reduction of oil leakage in production and the respective construction of wastewater and sewage collection and treatment systems, with regular inspections conducted.
Tung Ho Steel utilizes electric furnace refining and steel-rolling techniques, with production energy primarily coming from electricity. Given the high reliance on electricity, in order to effectively manage power usage, the company has invested in wave filters, capacitors, and other equipment to improve voltage and reduce system power loss. Through these efforts, electrical power usage efficiency has been raised to 99%.
During the period of peak power use in the summer months, we proactively cooperate by transitioning to off-peak power usage so as to maintain a balance between residential and commercial electricity usage. We also promote equipment improvements for energy savings to reduce energy consumption and to achieve annual power consumption reduction goals.
In order to reduce pollution emissions, Tung Ho Steel’s steel-rolling production line utilizes advanced burning equipment. A portion of production processes have changed over to natural gas in place of low-sulfur fuel oil, which has significantly reduced CO2, NOX and SOX pollutant emissions. The production process at the newly planned and completed Taoyuan Works employs direct rolling and extension of steel and does not feature heat furnaces. Compared to traditional steel-rolling, which uses fuel oil to heat the product and which can generate pollution, the new approach is more environmentally friendly.
In response to global warming, in order to effectively mitigate the impacts of climate change, Tung Ho Steel is actively promoting energy conservation and CO2 reductions, as well as proactively disclosing the carbon footprint information for its products. Through product carbon footprint inventory, it is possible to learn about the greenhouse gas emissions throughout a product’s lifecycle. This enables effective problem identification and implementation of low-carbon and energy-conserving design philosophies to increase service competitiveness.
Scrap material handling
Tung Ho Steel’s handling of scrap materials fully complies with legal requirements. Moreover, through improvements made to production processes and to equipment, it is hoped that goals for scrap reduction and for recycling and reuse can be achieved.
Friendly to the environment
Steel protects the environment and is an eco-friendly industry! Steel refining using electric furnaces as employed by Tung Ho Steel primarily utilizes steel scrap as its major source material. Compared to blast furnace and converter furnaces, which use large quantities of iron ore and coal, our approach has the advantage of offering resource recycling and reuse. In addition, electric furnace steel refining generates 75% less CO2 compared to blast furnace refining. This is of positive significance to the reduction of greenhouse gas emissions and the protection of the environment.
The company has spared no effort in the aspects of pollution prevention and control, reduction of industrial waste, and environmental protection. Many different types of plants are planted in factory areas to “green up” the environment. The aim is to rely on the plants to purify the air, absorb CO2, and achieve the goal of reducing CO2 emissions.
