Andritz successfully started up a fibrous reject compacting line for S.A. Industrias Celulosa Aragonesa (SAICA) at the El Burgo de Ebro mill in Saragossa, Spain. Three new Andritz Reject Compactors are part of an existing waste-to-power line and have the capacity to process 500 t of wet rejects per day. The wet rejects consist of various fiber residues and plastics produced in a recycled fiber processing line at the mill. The fiber is used in the production of industrial grades of paper. By removing the water and compacting the rejects, the heating value of the rejects is improved and Saica achieves higher electricity output from its power boiler and turbine-generator.
