Quang Ninh Cement and Construction Joint Stock Company: Linking production with environmental protection

To minimize the impact on the surrounding environment during the production process, Quang Ninh Cement and Construction Joint Stock Company has implemented many effective solutions. This is one of the cement production units that the Department of Natural Resources and Environment has assessed as having many good initiatives on environmental protection...

Automatic emission monitoring system of Quang Ninh Cement and Construction Joint Stock Company.

According to the original design in the 2007-2009 period, Lam Thach Cement Factory (Quang Ninh Cement and Construction Joint Stock Company) used electrostatic dust collectors (Clinker kiln stage of two production lines). However, due to dependence on the national power grid during operation, if there is a power outage, the electrostatic dust collector system of the Factory will suddenly stop operating, causing high-altitude dust generation.

To overcome this situation, from 2020 to present, the Company has renovated and improved the systems of 2 production lines with a total investment of more than 357 billion VND. Of which, 70 billion VND has been invested in renovating and converting 2 electrostatic tail dust collector systems to fabric bag dust collectors. The Company also invested in installing and putting into operation 2 NOx removal systems for 2 kiln lines to treat emissions generated at the factory's kiln chimney. Putting these systems into use helps the unit overcome problems with the power grid system, ensuring that dust emissions affecting the surrounding environment are completely eliminated.

In November 2020, the Company completed the installation of an automatic emission monitoring station system with a total investment of 12.5 billion VND. The monitoring works are installed at many locations such as: clinker kiln chimneys; clinker cooling; cement grinding; coal grinding. The results of dust and emission monitoring are continuously updated (every 5 minutes) and transmitted to the Department of Natural Resources and Environment for 24/7 monitoring, helping the factory to control dust and emission indexes well, detect and quickly handle incidents during the production process.

Aiming to develop production according to the circular economic model, in April 2022, Quang Ninh Cement and Construction Joint Stock Company launched an initiative to maintain the model of "Garbage Bank - Deposit garbage, withdraw money". This is the first "Garbage ATM" model implemented at a cement factory in Vietnam. Each kilogram of waste is equivalent to 1 conversion point, equivalent to 3,000-11,000 VND depending on the type of waste. When each person comes to deposit garbage, the Company will open an account to manage all data on garbage deposit activities. When the account reaches 300 accumulated points and the account owner has not withdrawn money, the Company will pay an interest rate of 1%/year. To attract more people to participate in the "Garbage ATM", the Company has many attractive programs, such as: Support for home delivery vehicles, purchase at a price 10-15% higher than the market price, interest support for long-term accumulation accounts, etc.

After more than 1 year of putting the “Garbage ATM” into operation, the Company has collected 120,000 tons of recyclable waste, spreading environmental protection actions. According to the Department of Natural Resources and Environment, the benefit of maintaining this model is also to raise awareness, encourage local people to care and join hands to protect the environment through waste classification, recycling, and turning waste into resources.

Quang Ninh Cement and Construction Joint Stock Company is effectively maintaining the model of "Garbage Bank - Deposit garbage, withdraw money".

In August 2020, Quang Ninh Cement and Construction Joint Stock Company and the People's Committee of Phuong Nam Ward (Uong Bi City) signed a coordination regulation on the effective implementation of environmental protection, security, order and social security in the period of 2020-2025. Accordingly, Phuong Nam Ward established and completed the Environmental Monitoring Team. The monitoring team is responsible for regularly monitoring and tracking the environmental protection work of Lam Thach Cement Factory 24/7; reporting and transmitting information to the People's Committee of the ward. From 2020 to the end of June 2023, the Environmental Monitoring Team has inspected and supervised 11 times related to environmental work at the factory.

Ms. Vu Thi Thuan, Hop Thanh area, Phuong Nam ward (Uong Bi city) said: Recently, Lam Thach Cement Factory has proactively implemented many solutions to improve the environment. The factory has invested in many environmental projects, planted trees, sprayed mist to suppress dust, maintained the "ATM trash" model... In addition, there is close coordination between local authorities and enterprises to create publicity and transparency of information related to the factory's environment. When receiving any information from people related to the environment, the Monitoring Team verifies the cause, makes a record and the Factory quickly fixes the problem.

On July 14, Phuong Nam Ward People's Committee and Quang Ninh Cement and Construction Joint Stock Company signed a memorandum of understanding on the results of implementing the coordination regulations on environmental protection, security and order, and social security for the period 2020-2023.

Mr. Vu Trong Hiet, Deputy Director of Quang Ninh Cement and Construction Joint Stock Company, said: Quang Ninh Cement and Construction Joint Stock Company continues to closely coordinate with Phuong Nam Ward in constructing welfare works, urban environmental improvement works at some key locations in the ward; proactively coordinate to manage and control all production activities of the Factory, minimize incidents affecting environmental sanitation; ensure state management of the environment in the area. At the same time, coordinate to establish and adjust planning to serve production and business, support site clearance, maintain and develop the "Garbage Bank - deposit garbage, withdraw money" operating model to residential areas throughout Uong Bi.
