Harsco Metals & Minerals

Tangshan Iron & Steel, the flagship site of China’s largest steelmaker, Hebei Iron & Steel (HBIS) Group, the second largest producer of steel in the world. In recent years Tangshan Iron & Steel has made environmental improvements in power consumption, water use and by-product recycling.

Emissions reduction
Tangshan Iron carried out a large scale investment in plant energy savings and emission reduction technology. Two new 450 cubic meter blast furnaces were dismantled, reducing dust emissions by 1600 tons one year, and sulfur dioxide reduced by 3000 tons.

In 2011 the company implemented 25 energy saving projects, and invested 2.68 billion RMB ($400m) in environmental governance and energy conservation.

Waste Water

Tangshan Steel also constructed North China’s largest industrial wastewater treatment centre, using the city’s recycled waste water as its only production water. After the project was put into operation, Tangshan Iron and Steel closed down all its deep wells, using city recycled water as the only production water, which achieved the goal of integrated treatment and recycling of industrial water in the region. Tangshan disposes of 3,000 cubic meters of industrial waste water every day, saving fresh water 14.6 million tons per year. The end result for Tangshan Steel was zero purchase of fresh water and zero emission of industrial waste water.

By-products

In 2012, Tangshan Steel signed a joint venture agreement with Harsco for the environmentally-beneficial handling and processing of steelmaking by-products.

Mr. Yu, Yong, Chairman and President of Tangshan Iron and Steel Group (Tangshan Steel), commented:
“This new project is a new beginning. While return on investment is important, Tangshan Steel takes more seriously what returns this project can bring to society in improving the environment.”

The new agreement will include advanced slag treatment processes for BOF and LAF slags, leading to significant reductions in environmental impact versus traditional methods, along with high-efficiency metal recovery and the manufacture of coproducts from the residual slags, for reuse into the cement, concrete and road base infrastructure markets.
