ENVIRONMENTAL MANAGEMENT IN PVCFC
![](img/common/qoute.png)
PVCFC ALWAYS STRICTLY COMPLIES WITH CURRENT REGULATIONS OF THE LAWS AND APPLIES ISO 14001:2015 (QUALITY POLICY, SAFETY, ENVIRONMENT, INSPECTION AND TESTING OF PVCFC) TO MONITOR ENVIRONMENTAL PROTECTION. THE PLANT’S WASTE RESOURCES ARE STRICTLY CONTROLLED TOWARD MINIMIZATION OF QUANTITY AND QUALITY CONTROL IN ACCORDANCE WITH DISCHARGE STANDARDS

Ca Mau Fertilizer Plant
Quality control of wastewater and emission
- Total river water exploitation: 14,497,300 m3
- Total water supply: 1,120,230 m3
- Total wastewater production: 13,292,179 m3
- Total emission production: 9,409,967,121 m3
Periodic environmental monitoring
Ensure quality of waste output causing no impact on surrounding environment, PVCFC has performed environmental monitoring periodically 4 times/year in accordance with environmental impact assessment commitments approved by Ministry of Natural Resources and Environment under Decision No. 1378/QĐ-BTNMT dated 5 August 2010, specific locations and environmental parameters as follows:
Location | Parameters | Vietnam Standards |
---|---|---|
|
Dust, CO, NOx, SO2, NH3, noise, vibration | 19/2009/BTNMT |
Domestic wastewater | pH, BOD5, TSS, TDS, surfactants, animal fat, vegetable oil, sulfide, Ammonia, total Phosphorus, total nitrogen, Coliform | 14/2008/BTNMT |
|
pH capacity, colors, BOD5, COD, suspended solids, Arsenic, mercury, lead, iron, copper, total mineral oil and grease content, sulfide, Ammonia, total nitrogen, total phosphorus, Ammonium, residual Chlorine, Coliform, wastewater capacity. | 40:2011/BTNMT |
|
Temperature, color, pH, BOD5, COD, TSS, total dissolved solids (TDS), Arsenic, Mercury, Lead, Cadmium, Cooper, Iron, total mineral oil and grease content, total surfactants, animal fat and vegetable oil, sulfide, Ammonium (as Nitrogen), total nitrogen, total phosphorus, residual Chlorine, Coliform. | 40:2011/BTNMT |
Output of waste heat driven refrigeration system | pH, temperature, Cl2, TSS | 40:2011/BTNMT |
All periodic environmental monitoring results in 2021 at all locations have been implemented with parameters in accordance with regulations and within acceptable limits.
Apart from conducing periodic environmental monitoring, PVCFC has also installed continuous automatic emission and wastewater monitoring systems in some locations with parameters as follows:
- River water for cooling and waste heat: temperature, pH, residual Chlorine;
- Output wastewater: capacity, temperature, pH, COD, TSS, NH4+;
- Emissions at Spout fluid bed granulator: capacity, temperature and NH3
Continuous automatic monitoring data is collected every 5 minutes/data and directly transmitted to Ca Mau Department of Natural Resource and Environment. In 2021, 100% of data was transmitted to Ca Mau Department of Natural Resources and Environment (except for time for plant maintenance) without any parameter exceeding allowable limits.
Control of solid waste
Domestic waste generated from offices, cafeteria, canteen, toilets, etc. with an amount of 121,581 kg has been collected and transferred to Ca Mau Urban Environment JSC.
Ordinary industrial solid waste: wood chips, damage pallets, plastic, scrap iron, etc. generated with an amount of 115,116 kg has been collected and transferred to competent units for treatment in accordance with regulations.
Hazardous waste: PVCFC has registered hazardous waste source owner, Code QLCTNH: 96.000016.T issued by Ca Mau Department of Natural Resources and Environment dated 23 December 2014. This was the 4th time PVCFC granted this owner. In 2021, hazardous waste generated with an amount of 167,666 kg has been classified, collected, stored at hazardous waste storage of the plant and transmitted to competent units for treatment in accordance with regulations.
Periodic planning and reporting
The Company, on an annual basis, works out periodic environmental monitoring plan and report on environmental protection in accordance with Decree No. 40/2019/NĐ-CP dated 13 May 2019, Circular No. 25/2019/TT-BTNMT dated 31 December 2019. These plans and reports have been submitted to Ministry of Natural Resources and Environment as well as Ca Mau Department of Natural Resources and Environment.
Besides, the Company has also conducted identification and evaluation of significant environmental aspects to set up appropriate environmental control programs for every unit of the Company.
Wastewater rate schedule
PVCFC always declares and fully pays environmental protection fees for industrial wastewater in accordance with Decree No.53/2020/NĐ-CP dated 05 May 2020 of the Government on environmental protection fees for wastewater.
