Method for transforming diverse pulp and paper products into a homogenous cellulosic feedstock

A method for treating diverse pulp and paper products derived from waste paper or MSW to produce a homogenous cellulosic feedstock comprising the steps of:

• feeding diverse pulp and paper products into a vessel;
• sealing the vessel so that the vessel is pressure tight;
• injecting steam into the vessel while agitating the products;
• saturating the products with steam at a temperature in the range of about 287° F. to about 312° F. and at a pressure in the range of about 40 psig to about 65 psig to expand the molecular structure of the products;
• depressurizing the vessel to further enhance the molecular expansion of the products;
• capturing any gases released during said depressurizing and treating said gases to render any volatile organic compounds and any air pollutants presents in the gases harmless;
• and
• discharging the processed products therefrom.
