Rotterdam, Netherlands, May 23, 2008 – Effective June 1, LyondellBasell Industries will increase prices by €40 per tonne on its polypropylene grades sold in Europe.

“This increase is due to escalating feedstock and energy costs which have been eroding our margins since the beginning of the year,” said Yves Bonte, Senior Vice President of LyondellBasell’s Polypropylene Business.
