(VEN) - In addition to producing fertilizer products that are good for plants and environment-friendly, the Van Dien Fused Magnesium Phosphate Fertilizer Joint Stock Company (VADFCO) has paid great attention to protecting the environment around its production facilities.
As a production unit in the capital city, the environmental protection work helps VADFCO not only stabilize production but also attract appreciative customers. The company therefore attaches great importance to investment in science and technology to drive towards cleaner production and sustainable development.
The company has applied technological solutions to recycle solid waste for use in fertilizer production. With a capacity of 300,000 tonnes of fused magnesium phosphate fertilizer each year, the company collects about 100,000 tonnes of fine ore, then uses additives and applies technologies to turn it into materials for fertilizer production, contributing to reducing material consumption and minimizing environmental pollution. The company has also signed contracts with units to collect some materials on the list of hazardous wastes and hand them over to relevant authorities for treatment in accordance with state regulations.
To produce one tonne of phosphate fertilizer, VADFCO has to use 44cu.m of water and discard 40cu.m of wastewater. As a result, the company has to use 14-15 million cu.m of water and discard 12-13 million cu.m of wastewater per year. To resolve the problem of wastewater, the company has conducted research and invested in a circular wastewater treatment system.
Its efforts to improve existing facilities and build new water treatment and circulation systems have enabled VADFCO to treat 100 percent of wastewater for reuse in production, saving 12-13 million cu.m of water annually. These efforts have also allowed the company to save more than five million kWh of electricity and take back several thousand tonnes of semi-finished products per year. These solutions have helped the company reduce production costs and enhance the competitiveness of its products.
The company has also installed dust filtration systems behind furnaces and product grinding and drying systems, while investing in improving the cross-section and volume of pipelines, ensuring the quality of exhaust gas according to regulations.
VADFCO has used compressed rice husk instead of coal to dry phosphate and NPK fertilizers in an effort to reduce greenhouse gas emissions, eliminate coal residues and minimize environmental pollution. This change has enabled the company to save VND5 billion each year. In addition, since 2012, the company has invested tens of billions of Vietnamese dong to improve dust treatment.
Automatic emission monitoring equipment has also been installed in chimneys, and data is transferred to environmental management authorities for monitoring.
In addition to investment in science and technology for thorough treatment of solid waste, wastewater, dust, and exhaust gas, VADFCO also seeks to raise the environmental awareness of employees. It disseminates the Law on Environmental Protection, explains the process of environmental protection and the handling of environmental pollution, and the application of cleaner production methods and advanced management systems such as ISO 9001:2015.
The company has planted trees and flowers around its production facilities, and launched environmental sanitation.
In addition to the collection and handling of hazardous wastes according to state regulations, the company has performed monitoring for wastewater and emissions periodically, compiled periodic reports for authorities, and executed inspection of state management agencies on occupational safety and health.
Occupational safety and health and environmental protection are a top priority of VADFCO, contributing to improving the company’s image, and increasing competitiveness of its products in order to achieve sustainable development.
