An official at the Gulf Petrochemicals and Chemicals Association (GPCA) said that the value of the petrochemical industry in the Gulf region exceeded $50 Billion. Deputy Director of GPCA's plastic committee Moayad Al-Farisi told KUNA, on the sidelines of the First GPCA Plastic Summit to conclude here Wednesday, that the Gulf Cooperation Council (GCC) states produced 13 percent of the world's plastic material. "That would increase to about 20 percent in the next five years," he pointed out.
