ENVIRONMENTAL PROTECTION - REPORT FOR 2011
Introduction
Petrokemija Plc., with its basic activities of fertilizer production, carbon black production and
bentonite clay-based products has a significant impact on environment. Major environmental
aspects are pollutant emissions to air and water and waste management. The overall objective of
the Company is to improve the performance of the environmental management system in order to
achieve a more effective environmental protection and pollution prevention. The frame and the
main guidelines of the strategic activities in the environmental and quality management are
established by the Environmental and Quality Policy. The key parts of the environmental
management system, their mutual effect and connections between organizational units are
described in Environmental Manual. The basic components of the environmental management
process are planning the environmental protection activities in accordance with legal and other
requirements, realization of the activities and assessment of environmental aspects in order to
prove the environmental protection improvement by measurable indicators.
The Environmental Management System of Petrokemija was made compliant with and certified
against the ISO 14001:2004 standard requirements.
1. Air pollutant emissions
The greenhouse gases, carbon dioxide and nitrous oxide were the most represented pollutants in
total emission to air from Petrokemija Plc. in 2011, the same as in the earlier years, with a share of
99 %. As regards other characteristic emissions (ammonia-NH3, sulfur dioxide-SO2, nitrogen
oxides-as NO2, gaseous fluorides-HF and dust), without greenhouse gases and carbon monoxide
(CO), ammonia and nitrogen oxides (as NO2) were the most represented pollutants in the emissions
from Petrokemija with a share of 60.36 % and 27.49 % respectively (Figure 1).

The total air emission in t/y (without carbon oxides: CO and CO2) was about 10 % lower as
compared to in 2010, which is satisfactory, as it is the result of increased production. In the 2007 to
2011 period, there was a falling trend for nitrogen oxides (as NO2), sulfur dioxide (without
emissions from carbon black production), ammonia and fluorides. There was almost
2/4
a stationary trend for dust and due to interruption of carbon black production in the last two years
there was no emission of hydrogen sulphide.
As regards emission factors of individual pollutants, a decrease per product unit was established
for all pollutants in comparison to those in 2010 except for dust. With regard to the in-force
prescribed emission limits, in line with the Regulation on Emission Limit Values...(OJ 21/07 and
150/08), the limit emission concentrations for ammonia, dust and nitrogen dioxide exceeded in
several cases at several outlets.

With the aim of further improvement, measures are being undertaken for bringing the existing
facilities in compliance with the Environmental Protection Act as prescribed in the Adjustment
Plan adopted by the European Commission. Priority improvement measures are designed to
improve the operations at the NPK1 and UREA Plants as well as measures to reduce greenhouse
gas emissions.
2. Air quality in the Kutina area
In 2011, on the basis of results of air quality monitoring at six measuring stations of the local
network (Figure 3), for 7 pollutants (NH3, SO2, NO2, H2S, HF, dust and total sediment), 1st
category (clean or slightly polluted air) was established for all pollutants (Table 1). According to
unofficial measuring results of the State Measuring Station for particulate matter of 10 m (PM10)
and for hydrogen sulphide concentrations, 3rd category or excessively polluted air was determined.
For H2S this cannot be associated with the Petrokemija production due to the halt of carbon black
production. As for dust, there are other sources that contribute to its emission.

Although the long-standing concentrations of all characteristic air pollutants have a falling trend
(e.g. ammonia, Figure 4.). Same goes for the mean concentration trend for the past three years,
except for nitrogen oxides (as NO2) and smoke.

4. Waste management
In the course of 2011, Petrokemija Plc. together with municipal solid waste generated 34 kinds of
waste, 13 of which were hazardous. In addition, one kind of external hazardous waste was treated.
Approx. 85% of total quantity of waste handled within Petrokemija Plc. was disposed at the
Company's own disposal, and the rest was given to external authorized waste collectors or
processing companies. In 2011, no phosphogypsum waste was generated due to the temporary
shutdown of phosphoric acid production.
As regards the results of obligatory monitoring of the phosphogypsum disposal environment, the
average annual concentration of underground water pollution (Figure 6.) was under the limit values
for drinking water.
