After what Stora Enso described as a "small investment," and some six months of test runs carried out since the beginning of the year, pulp line 1 at Enocell mill has been producing dissolving pulp exclusively since June, RISI reports.The line, which can swing back to regular production of bleached softwood kraft pulp if required, has a capacity of 150,000 tons per year.Fexibility was the key consideration in the decision to move ahead with production of dissolving pulp, according to a Stora Enso spokesman. "We can take advantage of the higher margins of dissolving pulp, when the market situation is good, and if not, we can run the line with good quality regular pulp," the spokesperson told RISI.Stora Enso Enocell has a total capacity of around 500,000 tons per year.
