Natanz Steel Complex is committed to reducing the environmental impacts of its activities and products by using appropriate methods and continuous improvement in operations, observing general principles such as compliance with laws and regulations, effective deployment and continuous improvement of the environmental management system, participation in reaching to sustainable development, management of products, appropriate monitoring and reporting, incentives and encouragement of suppliers and contractors in order to preserve the environment and minimize attention to environmental social responsibilities.
Environmental activities during the implementation of the project
- This industry is essentially a large consumer of metal waste as raw materials for steel production, which plays an important role in the recycling cycle of metal waste.
- Using natural gas and electric energy as clean energy sources.
- Installation and operation of bag filter type dust collectors for all air polluting parts
- Using a closed industrial water system with an equipped house for cooling the product and equipment
- Construction and start-up of sanitary wastewater treatment house using biological method of activated sludge type and using its effluent to irrigate green space.
Environmental performance of Natanz steel complex
The environmental performance of Natanz steel complex can be classified into the following sections.
- Natanz steel environmental policy
- Creating plans to achieve goals
Wastewater treatment and recycling
In order to save resources and prevent environmental pollution, this huge industrial complex cleans and reuses all its production wastes.
- Wastewater treatment plant of rolling lines
- Wastewater treatment plant of steel production line
- Sanitary sewage treatment house
It is worth mentioning that with the implementation of a special plan, it is possible to reuse the waste water in the production line in times of water scarcity.
Construction and installation and development of air pollution control equipment
In order to prevent pollutants from entering the environment, Natanz Steel Complex has been installing air pollution control equipment, including hoods, scrubbers, etc., since the time of its construction. It should be mentioned that the dust collection system of the steel factory is one of the most equipped and up-to-date dust collection systems.
A look at the environmental projects completed in Natanz steel complex
- The plan of completing and upgrading the dust collection systems of the steelmaking unit
- Complete design and control of sanitary wastewater treatment process for use in green areas
The project of improving the dust collection system in the steelmaking area
1- The effects of the implementation of the new dust collector modification plan on the environmental performance of the company in the steel industry
- With the completion of this project, a part of the dust from the scrap charging that comes out periodically from the roof will be under revenue control (the amount of output dust is 120 mgr/m3 under revenue control)
- It became possible to manage and perform repairs on dust collection systems with considerable flexibility.
- By installing a chimney and creating a new system for dust guidance, the possibility of on-line sampling was provided.
- The general and sometimes incorrect concerns of the region about the possible effects of dust dispersion from this area were resolved.
2- Wastewater recycling plan for the production process
By modifying and making changes in the sanitary treatment plant system and monitoring its good performance, it is possible to use water for green spaces and agriculture, which has caused a reduction in water consumption.
Green space and vegetation
One of the valuable actions of Natanz Steel Complex is the creation, expansion and maintenance of various types of plants, suitable for the water and air conditions of the region. Selecting suitable plant species for the region and investigating the effect of irrigation regimes and the effect of air pollutants on them, based on the results of the project Taxonomic research has been done on trees and shrubs.
More than 75% of the mentioned green space is irrigated through treated wastewater, most of which is in the form of drip irrigation.
