According to an example aspect of the present invention， there is provided a process for the conversion of cellulosic waste material into a recycled cellulose product comprising the steps of cooking the waste material in a cooking liquor to remove lignin from the waste material and provide a delignified pulp，dissolving the delignified pulp in an ionic liquid to provide a spinning dope suitable for dry jet-wet spinning in an ionic liquid solution， and subjecting the spinning dope to a further processing step to provide a recycled cellulose product， said further step selected from the group of spinning cellulose fibers for use in textiles from the solution，extruding a film product for use in packaging，regenerating the dope as a hydrogel and regenerating the dope as an aerogel.
