Abstract: A method of making a paper-based product includes substantially continuously treating a papermaking furnish including from greater than 0% to 100% recycled fibers with a biocide, and forming the furnish into the paper-based product. The furnish has a microorganism level of greater than 5,000 colony forming units per gram, and substantially continuously treating the furnish with the biocide reduces the microorganism level so that the paper-based product has a microorganism level of less than 5,000 colony forming units per gram.

Abstract: A ticket stock and manufacturing process wherein a pulp is formulated from a blend of recycled printed papers, with added starch for enhancing sheet stiffness and reducing linting and dusting on cut edges of the stock. A preferred pulp comprises a blend of printed solid bleached sulfate plate stock, printed white groundwood-free paper, and printed groundwood paper such as printed newsprint or the like. In one embodiment, the blend comprises about 25-50 wt. % printed solid bleached sulfate plate stock, about 15-40 wt. % printed white groundwood-free paper, and about 15-40 wt. % printed groundwood paper. The printed papers are repulped with minimal mechanical refining, treated with steam injection for hydrating and softening the fibers and breaking up inks into fine particles, and formed into a web that is pressed, dried, and soft calendered. The caliper of the resulting stock is about 7 to 9 points.
