With the goal of garden-style factory, Tianzhu Group promotes greening inside and outside the plant, with a green area of 2,400 mu and a greening rate of nearly 70%. It has taken the initiative to undertake the afforestation work of more than 1,600 mu of the first and fourth lines of Fengrun District, which has realized the overall greening pattern of the garden factory with flowers in spring, shade in summer,scenery in autumn and green in winter. By adhering to the objective of "factory in the forest and forest in the factory", Tianzhu has always been strive in this direction.
Tianzhu Group has invested more than 3 billion yuan to promote environmental protection, built 120 sets of atmospheric treatment facilities, and all materials have realized closed management to prevent dust from escaping and zero discharge of production wastewater. In order to further improve the environmental protection effect, in 2018, more than 20 environmental protection projects have been renovated, such as sintering and shaft furnace desulfurization deep treatment,blast furnace and converter dust removal system transformation, strip steel dust removal system construction, plant and pipeline alure closure, etc. The sulfur dioxide has reached the ultra-low emission standard below 30mg/m3 and the smoke emission index is superior to the national standard which is reaching the domestic advanced level. Currently, Tianzhu is promoting the construction of smoke-free factories, and is committed to becoming a benchmark enterprise for environmental protection in the steel industry.
In recent years,Tianzhu Group has invested nearly 1 billion yuan to develop a circular economy.
The company has invested a total of 550 million yuan to build 11 sets of generator sets. In 2017, the self-power generation capacity was 749 million kWh, the self-generation rate was reached over 70%, and the annual standard coal was saved 92,000 tons. From January to September 2018, the self-generation capacity has reached to 1.1 billion kWh.
It has built 4 sets of steel slag comprehensive treatment facilities and 2 slag powder production lines to realize the value-added and recycling of industrial waste.
It has constructed a sewage treatment facility with a daily processing capacity of 15,000 tons,which has realized the recycling of industrial water, improved the utilization efficiency of new water, and achieved zero discharge of industrial wastewater.
The company has also actively responded to the government's coal-to-gas project deployment. It invested about 150 million yuan in 2017 to build a new blast furnace slag water waste heat recovery project, which is connected with the municipal pipe network to solve the heating problem for the city. According to the planning and design, 3.5 million square meters of central heating can be provided for urban areas. In 2017, 1.25 million square meters of central heating have been achieved, and nearly 20,000 tons of standard coal have been saved annually. The project has been incorporated into the "Tangshan Fengrun Urban District Central Heating Plan (2017-2030).
