摘要:
A method for manufacturing a cellulosic paper material (150) is described. The method comprises: i) providing (105) used textiles as starting material (101), wherein the used textiles comprise cellulose and non-cellulosic foreign matters (in particular synthetic plastics and/or metal oxides), ii) at least partially depleting (120) the non-cellulosic foreign matters from the cellulose, to provide a depleted starting material (110), and iii) forming (170) the cellulosic paper material (150) from the depleted starting material (110). Furthermore, a cellulosic paper material (150) made of recycled used textiles and a use of used textiles for providing a cellulosic paper material (150) are described.
