International technology group ANDRITZ has successfully started up key production equipment for the first of two environmentally friendly hardwood pulp production lines supplied for Bracell’s “STAR” project in Lençóis Paulista, São Paulo. The second line is expected to be started up by the end of September.

Project STAR is one of the largest and most sustainable pulp mills in the world, operating with the highest environmental standards. It features two flexible, environmentally friendly hardwood fiberlines for a capacity of 2.6 to 2.8 million tons/year of bleached kraft pulp or 1.5 million tons/year of dissolving pulp made from sustainably cultivated eucalyptus.

The ANDRITZ A-ConFlex^TM continuous kraft and dissolving pulping technology enables flexibility in production of high-quality dissolving pulp and kraft pulp. With this delivery, ANDRITZ once again confirms its position as the only technology supplier with solid references and experience in continuous cooking of dissolving pulp. With a capacity of 13,000 tons per day, the ANDRITZ HERB^TM recovery boiler is the largest in the world. It will make the mill self-sufficient in energy supply and additionally produce around 180 megawatts of green energy for the Brazilian grid. This covers the energy consumption of about three million people in the region.
