EUROPEAN REFINERS CUT OIL CONTENT IN DISCHARGES
Western European refiners have reduced the oil content in discharge waters while increasing throughput. A report by Concawe, Brussels, the oil companies' European organization for environmental and health protection, compiles data from members responding to a questionnaire on 1990 performance. Replies represented 80% of the refining capacity in western Europe. They show a 35% reduction in the ratio of oil discharged to oil processed since the previous survey in 1987.
