Renewable materials account for an inconsiderable proportion of total materials; therefore, they are not included in this table.
Raw materials for NPK production technology include liquid materials (such as Urea, NH3, H2SO4…) and solid materials (such as Urea granules, MAP, DAP, SA, MOP, SOP, etc). In which, steam makes an important role to enable the process of forming products in granulators more easily and provide energy for granulation process. Natural gas along with air is used as fuel for combustion chamber and hot air generated from fuel combustion is used for cooling and drying products. Increasing production capacity leads to the increase in annual raw material usage.
Water is an essential element in daily production and operation. However, this important resource is facing the risk of depletion and pollution due to unsustainable exploitation and climate change.
Total water consumption at PVCFC in 2024 was 1,269,647 m3, an increase of 4.05% compared to 2023 (1,220,266 3). In which:
Total amount of river water exploited in 2023 was 16.45 million m3 and in 2024 was 14.99 million m3;
Total amount of wastewater in 2023 was 72,747 m3 and in 2024 was 57,164 million m3;
Water consumption is reduced thanks to water saving measures, awareness of each employee in water use and operating the Plant at a higher capacity. The amount of water consumed per ton of product in 2024 decreased by 1.98% compared to 2023. In the end of 2024, Ca Mau Fertilizer Plant put into operation the system of recovering wastewater from RO filters, saving 17 m3/h from discharged concentrate, saving more than 145 thousand m3 of water per year, and at the same time, helping reduce the load of old RO system and reduce the amount of chemicals used in water treatment system.
Waste control is an important goal of PVCFC, which is not only a legal responsibility but also a commitment to environmental protection. PVCFC applies advanced technology to minimize environmental impact and improve production efficiency. The Company always complies with legal regulations towards building an enterprise of environmental protection. In 2024, there were no violations or incidents related to waste pollution at PVCFC. The Company complies with regulations on waste collection, classification, and treatment, ensuring that waste storage system meets legal requirements, fully implementing waste management procedure to avoid errors that affect the environment
Total energy consumption in 2024 at PVCFC increased by 0.34% compared to 2023. However, energy use intensity decreased by 5,48% compared to 2023. The results of energy use in 2024 at PVCFC are as follows:
Energy Type | Unit | 2023 | 2024 | Ratio |
---|---|---|---|---|
Total Renewable Energy Consumption (1) | NA | NA | NA | NA |
Total Non-Renewable Energy Consumption (2) | GJ | 20,831,892.79 | 20,902,086.34 | Increase 0,34% |
Total Energy Consumption (3) = (1) + (2) | GJ | 20,831,892.79 | 20,902,086.34 | Increase 0,34% |
Energy usage intensity | GJ/million tons of products | 19.07 | 18.03 | Decrease 5.48% |
According to the business plan until 2025 as approved in Resolution No. 6395/NQ-DKVN of Vietnam Oil and Gas Group, the goal set for Ca Mau Fertilizer Plant is to save energy, in which the energy consumption rate by 2025 will decrease by 5% compared to 2022. By the end of 2024, Ca Mau Fertilizer Plant has reduced the energy consumption by 4.38%/5% thanks to applying many improvements to increase output and decrease energy compared to 2022.

Climate change is increasingly posing significant challenges for enterprises, primarily through two major risks i.e. physical risks (extreme weather events such as storms, floods and droughts causing damage to infrastructure and disrupting production) and transitional risks (related to the transition to low-carbon economy driven by changes in government policies, technologies and consumer preferences). In response to climate change, PVCFC proactively assesses risks, develops sustainable development strategies, and invests in sustainable solutions. The company has implemented policies and procedures to minimize the impact of production and business on climate change. The Company also focuses on assessing the environmental impact from the early stages at Ca Mau Fertilizer Plant and researches to reduce emissions and use fertilizers effectively.
In 2024, preliminary calculation based on main emission sources at PVCFC showed that total emissions increased by 1.43% but emission intensity/ton of manufactured products decreased by 4.45%, demonstrating the effectiveness of improvements and emission reduction solutions at Ca Mau Fertilizer Plant.
Emission activities | Unit | 2023 | 2024 | Change from 2023 |
---|---|---|---|---|
A. Direct emissions (1+2) | Ton CO₂/year | 395,387.80 | 397,890.54 | Increase 0.63% |
B. Indirect emissions | Ton CO₂/year | 124,694.46 | 129,614.89 | Increase 3.95% |
Total of emissions (A+B) | Ton CO₂/year | 520,082.25 | 527,505.43 | Increase 1.43% |
Emission intensity | Ton CO₂/ ton of products | 0.476 | 0.455 | Decrease 4.45% |
We have some adjustments in calculating GHG emissions in 2024 compared to 2023 as follows:
Given awareness of the harmful effects of discarded batteries, as a single discarded battery can pollute 500 liters of clean water and one cubic meter of soil for 50 years, PVCFC has pioneered the program “Giving old batteries – Getting new presents” in 2024. The program not only encourages employees in the Company to collect discarded batteries but also spreads a strong message about environmental protection
After a period of implementation, the program has helped collect 224 kg of old batteries - an impressive number that reflects PVCFC’s sense of responsibility and commitment on the journey of joining hands for a greener and cleaner environment. This is a vivid demonstration of PVCFC’s persistent efforts towards sustainable development, not only in production and business but also in protecting the ecosystem and the community.
