ENVIRONMENTAL PROTECTION - REPORT FOR 2010
Introduction
Petrokemija d.d., 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 d.d. in 2010, 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 55.2% and 32.1% respectively
(Figure 1).

The total air emission in t/y (without carbon oxides: CO and CO2) was only by about 4 %
higher as compared to in 2009, which is satisfactory, being the result of increased production.
In the 2006 to 2010 period, there was a falling trend for nitrogen oxides (as NO2), sulfur
dioxide (without emissions from carbon black production), ammonia, hydrogen sulphide,
fluorides and dust. As regards emission factors of individual pollutants, a decrease per
product unit was established for all pollutants in comparison to those in 2009. With regard to
the stricter prescribed emission limits in force since 01.01.2010, in line with the Regulation
2/5
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.

In order to improve the system, a situation analysis was made and measures were provided
for bringing the existing facilities in compliance with the Environmental Protection Act as
prescribed in the Adjustment Plan adopted by the European Commission. Some of the
planned measures are included in the Plant Modernization Plan and the City of Kutina
Plan of Measures for Reduction of Air Pollution. Priority measures are designed to
improve the operations at the NPK1 and UREA Plants.
2. Air quality in the Kutina area
In 2010, 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 ammonia and particulate
matter of 10 m (PM10) concentrations, 2nd category, or moderately polluted air quality was
established. For hydrogen sulphide, 3rd category or excessively polluted air was determined,
which cannot be associated with the Petrokemija production due to the halt of carbon black
production since June 3, 2009.

Although the long-standing concentrations of all characteristic air pollutants have a falling
trend (e.g. ammonia, Figure 4.), placing a number of measuring stations into second airquality category indicates the need for further efforts to reduce emissions. Same goes for
the mean concentration trend for the past five years, except for the total sediment and
fluorides.

3. Water management
In 2006 to 2010 period, the degree of waste water pollution in terms of pollution factor (k1)
indicates a trend of decrease (Figure 5a). Nitrogen concentration in the spot waste water
samples indicates a trend of increase, but is still below the limit value (Figure 5b), as well as
other parameters whose monitoring is prescribed by the Water License.

4. Waste management
In the course of 2010, Petrokemija d.d. generated 28 kinds of waste, 13 of which was
hazardous. In addition, one kind of external hazardous waste was also disposed of.
Approx. 88% of total quantity of waste handled within Petrokemija d.d. was disposed at the
Company's own disposal, and the rest was given to external authorized waste collectors or
processing companies. In 2010, 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.
