The Client PolWAX S.A. is one of the largest European producers and distributers of refined and deodorized paraffin, waxes and specialty industrial paraffin compositions. The new plant with an annual capacity of 30,000 metric tons of three individual slack-wax grades will be integrated into the existing production site of PolWAX at Czechowice-Dziedzice.
