Environmental and social responsibility
Two accelerators (A-4 and A-5) from water decarbonisation
process were used in the 3rd stage of wastewater
treatment. Here it was possible to repeatedly use sediment
from raw water decarbonisation process in wastewater
coagulation process.
Wastewater is used as industrial water for cleaning,
washing and fire fighting purposes.
The new technologies yielded environmental and economic
benefits. The volume of water uptaken from and wastewater
discharged to the Vistula has significantly dropped.
However, the closed water circuit, apart from advantages,
caused certain problems and restrictions. In 2000,
we resigned from directing reversed wastewater to cooling
systems, as it resulted in excessive salinity of water at water
blocks. High salinity of circulating water made it necessary
to desalt cooling systems and as a consequence caused
increased ballast water discharge to the wastewater
treatment plant. Thus, in order to be able to still use
recycled water, we will have to reduce salt consumption
in the water and wastewater system. Proposal to be applied

in this scope may be the use of membrane processes,
e.g. reverse osmosis process (in place of ion exchangers)
which is carried out without the use of chemicals.
In 2008, we reported a significant drop in the amount
of gene rated waste in the group of waste other than
hazardous. This was the effect of completion in 2008
of preparatory works for investments projects. Works carried
out in 2009 were not associated with generation of increased
amount of waste. The amount of recovered waste
remains stable at approx. 90% ratio to generated waste.
In 2009 we generated 4.7 thousand Mg of hazardous
waste, of which 3.5 thousand Mg were directed to recovery
processes outside the territory of Poland, whereas
the remaining 1.2 thousand Mg of hazardous waste were
supplied to Polish recipients.
In 2009, no accidental release of hazardous substances
happened at the Production Plant in Płock which could
affect human life, soil, vegetation, water reservoirs or underground
water.
Transfer of hazardous waste in 2009 was carried out
in the following way:
• within the territory of Poland
– for the purpose of recovery – 265.0 Mg,
– for the purpose of neutralising – 502.4 Mg;
• to other countries for the purpose of recovery –
4,372.4 Mg.
This applied both to waste generated in 2009 and stored
from the previous years.
The proper operation of the Production Plant in Płock
was checked by the Masovian Regional Environmental
Protection Inspectorate, which performed 3 checks
in 2009, of which one was a comprehensive check, one
was investment project check and one was a check with
respect to major failures. The results of the checks did not
reveal any parameters in excess of the limits determined
in relevant permits and decisions, and no penalties were
imposed. A post-check disposition was issued stipulating
recommendations concerning the requirement to notify
the Regional fire Service Chief and the Regional Environmental
Protection Inspector about the date of termination
of the use of Olefin I unit.
