Abstract: This invention uses lignin, which is the main chemical by-product of the original pulping process in manufacturing wood pulp for use in cardboard and paper, to create a repulping solution Lignocellulosic Hornification Remover (“LHR”) comprising a customized mixture of dipolar aprotic such as dimethyl sulfoxide (DMSO) and water, the LHR having greater frequency and energy and lignocellulosic hornification removal results than pure DMSO or other cellulose swelling chemical agents previously used in conventional repulping. The LHR creates and secures a special type of swelling (“intramicellar swelling”) in the material being re-pulped. Intramicellar swelling is a dimensional type of swelling, not the normal swelling of pulp material which is a directional one. The intramicellar swelling influences and breaks down both the intra- and intermolecular H-bonds of both amorphous and crystalline cellulose (i.e.

Abstract: An enhanced method of repulping paper and improving water quality by placing used paper product material in an aqueous solution of dipolar aprotic protophylic solvent, processing it, and recovering recycled pulp based on two physical reactions of the dipolar solvent: first with water from one part of the solvent, and second with cellulosic material from the other part of the solvent. The water reaction involves a rearrangement of hydrogen bonds within the water, improving its reactivity and solvent capacity, and the cellulosic reaction involves dissolution of hemicellulose in a manner which results in reduced fibre loss and improved pulp quality. The net result is more efficient pulping and reduced environmental impact.
