In 2006, we registered the following environment influence parameters:
- Volumes and types of pollution emitted to air In 2006 total emission volume (excluding CO2) amounted to 9,928.3 tons (t) of dust and gas pollution.
| sulphur dioxide (SO2) carbon monoxide (CO) nitric oxides flue dusts ammonia urea dust nitrogen fertiliser dust phthalic acid anhydride | 2,958.0 t/year 2,849.6 t/year 2,766.3 t/year 541.8 t/year 392.5 t/year 171.3 t/year 140.8 t/year 65.5 t/year |
Total emission of the abovementioned types of pollution amounted to 9,885.8 t/year, which constitutes 99.57% of emission. Emission of remaining 20 types of pollution amounted to 42.5 t/year, which constitutes 0.43% of emission.
Moreover, 1,041,729.5 t of carbon dioxide was emitted.
Moreover, 1,041,729.5 t of carbon dioxide was emitted.
The per cent share of the major types of pollution has been presented in the diagram below.
The emission level in 2006 has been quantified on the basis of:
- permanent emission measurements in the Company heat and power plant,
- periodic measurements of the main technological sources,
- balances prepared on the basis of technological indicators for the remaining emission sources.
- Volume and type of intake water
Volumes of different water types were as follows:
| water from the Odra river | 619.8 thousand m3 |
| water from the Łącza stream | 2,157.4 thousand m3 |
| water from Tertiary reservoirs | 854.8 thousand m3 |
| water from Quaternary reservoirs | 1,421.1 thousand m3 |
| water from KPP Kotlarnia | 1,481.4 thousand m3 |
The per cent share of the abovementioned water types in the total water intake has been presented in the diagram below:
Waters are used for: power, production, economic, social, and technological purposes.
Due to various applications, the following types of water are manufactured:
- industrial water
- drinking water
- pre-cleaned water
- softened water
- partially demineralised water
- demineralised water
The biggest water recipients are power installations (ca. 50% of water intake) and fertiliser installations (ca. 35%).
- Volume of sewage and pollution load discharged to the Odra river
In 2006, the total volume of discharged treated sewage was 3,416.1 thousand m3.
Major types of pollution discharged in ZAK S.A. sewage are:
| organic compounds marked with the COD parameter | 203.5 t |
| nitrogen | 234.8 t |
| chlorides | 798.7 t |
| sulphates 470.6 t | 470.6 t |
The following additional parameters are monitored in the discharged sewage: sewage reaction, BOD5, ammonia nitrogen, nitrate nitrogen, suspension, ether extract, phosphorus, formaldehyde, volatile aromatic hydrocarbon (BTX), volatile phenols, petroleum derivatives and metals.
- Types and volumes of generated and stored wastes, packaging
In 2006, regarding the waste management:
| generated | 119,413.5 t of wastes |
| designated to storage | 8,388.6 t of wastes |
| transferred to reclamation | 91,275.8 t of wastes |
| including ash-slag mixture | 85,366.8 t |
| transferred to neutralisation | 5.3 t of wastes |
The following types of wastes had the biggest share in the total waste generation:
| ash-slag mixtures | 90,102.78 t |
| debris wastes | 20,618.00 t |
| wastes from tank cleaning | 2,991.20 t |
| slimes from biological sewage treatment | 1,658.30 t |
| steel scrap | 1,462.12 t |
| distillation residue bottoms | 519.32 t |
| slimes from sewage treatment other than biological | 496.79 t |
| oils from the sewage treatment process | 392.36 t |
The per cent share of the major types of wastes has been presented in the diagrams below.
Together with the finished products, ZAK S.A. has also put packaging on the home market. This packaging is intended for recycling or reclamation.
Quantity of packaging put on the home market together with the finished products – 1,428.8 t
including: plastic packaging – 1,335.9 t
wooden pallets – 92.9 t
By ongoing cooperation with the recovery organisation, the regulation level of the packaging recycling (22% for plastic packaging) and the regulation level of the reclamation (43% for all packaging) have been achieved.
