Dong Lam Cement Co., Ltd with the Environmental Protection campaign!

Cement is essential in the development of infrastructure, and there currently needs to be a substitute for any building material. However, cement manufacture generates dust, heat, noise, and other environmental pollutants. Manufacturers must accept responsibility for severe environmental protection standards in cement manufacture and operations.

Explanation

It has an annual capacity of around 1.6 million tons of clinker and more than 1.8 million tons of cement. In recent years, in addition to the mission of producing and operating a business with excellent economic efficiency, Dong Lam Company has always regarded ecological conservation as an essential obligation.

In particular, the production characteristics of dust, pollutants, and noise... Dong Lam, Vietnam Cement Factory, has applied various solutions since its inception. To gather dust, it has closed storage facilities, pocket filters, and electrostatic dust filters. The factory has enhanced its utilization of exhaust heat to dry the crusher, reducing secondary combustion chamber operation, emissions, and expenses.

Implementing trial programs, using byproducts from other sectors as additives, and reducing clinker consumption all help to reduce CO2 emissions. Cement Crushing Station Project No. 2 is also wholly seated; synchronization of gear mechanism for the use of various industrial additive products; investment in NOx emission treatment system...

The facility also invests in systems to handle and collect wastewater, exhaust gases, and solid waste, as well as infrastructure, restraining equipment, and GHG prevention. So far, the unit has planted green trees across the manufacturing grounds, creating "soft" green belts that contribute to a clean, safe, and efficient working environment.

Through the establishment, maintenance, and evolution of an effective system of operations in environmental management, the factory is always in control, minimizing the impact on the working environment, landscape, and population, guaranteeing the highest safety and occupational health for the workers.

Environmental Production Technology

Harness is investing in improving the system that uses heat to cool down the cement crusher, replacing the heat from the combustion chamber and reducing oil consumption.

The production technology line is selected with advanced and modern equipment, a dry rotor with a 05-story heat exchange tower, and an advanced TTF decomposition chamber with good ability to use low-fuel; operating this system helps to save energy, produce high-quality, stable products, operate reduced NOx emissions to protect the environment.

To be more proactive in the treatment of NOx emissions, the plant continues to invest in and put into operation the NOx disposal system using the SNCR technology last year, which has additional treatment solutions, boosting the plant's capacity to manage NOx emissions into the environment.

The second cement crusher project is investing in a new fully automatic loader and container system from the well-known German business Haver Boecker in order to maximize production while minimizing dust emissions. It's incredible how the container-filling system automatically replaces individuals, lowering the environmental impact of dust on workers' health, especially in the containment area.

Given the demands of the common labor market for mechanization of stacking and transfer, the factory has invested in automatic cement stacking and export lines to improve heavy, toxic working conditions, in line with the increasing demands of labor regulations and environmental protection.

The investment project of an equipment system that utilizes emissions heat to generate electricity is being implemented in order to deliver economic efficiency, protect the environment, and reduce emissions of dust and heat to the environment.

The plant will also make the most of the drainage water from the limestone mining moong for treatment, bring it back to the reuse plant for production, contribute to solving environmental problems, and make efficient use of water resources while saving the cost of using the clean water source used for production.

Dong Lam Company also uses new raw materials and additive products from other industries, particularly supplementary mineral additives, to improve product quality, reduce production costs, and protect the environment. For example, ashes and particulates have explicitly been tested and used as active mineral additives in cement production to reduce the amount of clinker used, emissions, the use of fossil fuels, storage areas, burial sites, and environmental pollution.
