Depending on the requirements, ANDRITZ MeWa plants include several shredding stages in order to break down the stubborn rags properly. The robust machine technology with its very hard wearing cutting gear releases the metals (accounting for up to 40% of the content) completely. Impurities are separated into different fractions by subsequent separation processes. The calorific materials are further processed to provide substitute fuels.
