Abstract

A method of treating used paper in order to re-constitute it, and re-use it for paper products comprises the dry removal of foreign material, and heavy contaminants, and the separation of teh paper fibres by submitting the used paper to mechanical treatment in a container with a highly concentrated aqueous medium to effect: (1) the separation of the fibres from each other, and from their contaminants, (2) a pressurised fragmentation of the contaminants and (3) an homogenous dispersion of the fragmented contaminants in the fibrous dispersion thus obtained. The concentrated pulp, containing the dispesed contaminants is afterwards treated in a conventional manner to remove the contaminants before submitting it to papermaking machinery. The method, handles ink, glue, binders, bitumen, paraffin wax and plastic. It disposes of hooks, pins, sand, stones, glass and other heavy contaminants previously. The process avoids the manual sorting operating and permits the use of old, recovered paper normally reserved for inferior quality re-used paper products.
