Abstract
This invention relates to an improved method and apparatus to effect the separation of component fractions from paper-containing and plastic-containing waste materials. This method and apparatus accepts materials of widely varying characteristics such as paper, plastics, glass, metal, food wastes and other materials to be inserted en masse into a rotating vessel equipped with lifting paddles and directional flighting. In this way the intimate contact of materials with moisture and heat is accomplished, thus effecting the repulping of paper materials. The repulped materials, as a result of directional tumbling, are dispersed throughout the vessel. Because of the repulping of the pulpable materials, size reduction of the randomly large and odd-shaped pulpable materials is accomplished. By virtue of the size reduction of the large and odd-shaped pulpable materials, the non-pulpable components are freed of the particle shapes and surfaces that affect separation. The repulping of the pulpable materials increases the bulk density of those materials, further enhancing their separation from the additional components. The recovered pulped product is suitable for recylcing into the paper industry; for combustion as a high quality fuel; or for use as a feedstock for conversion into chemicals. The recovered non-pulpable material such as plastics, glass, metals, aluminum and other materials are suitable for recylcing into their producer industries; as feedstock raw materials for additional manufacturing of products; or any or all of these materials can be disposed of in a sanitary landfill as is the commonly accepted practice.
