GB No. 9, autumn 1992
The chemical compound (C2Cl4) used in dry cleaning, happens to be particularly harmful both to human health and the ozone layer. The people working at the dry cleaners' shops have to take a month long holiday every quarter to offset the effects this compound has on their systems.
The dry cleaning technology of the Kraków's plant entails the use of 440kg of (C2Cl4) per month. Considering, that the efficiency of the equipment is only 90%, ca. 10% of the chemical - 44kg - is thus being released into the atmosphere on the monthly basis. Apart from that, particularly dirty or stained clothing is being treated with an even more harmful substance - C2HCl3.
