Abstract: A method of separating waste material to a plurality of separated materials is disclosed herein. The method is effected by subjecting the waste material to a separation according to specific gravity, to thereby obtain two or more fractions, and optionally subjecting one or more of said fractions to additional separation procedures, to thereby obtain two or more of a low-density polymeric material, a high-density polymeric material, a metal, a glass, an oil, and lignocelluloses. The disclosed method can further be effected by processing one or more of the separated materials to thereby obtain one or more processed materials of a beneficial use. Further disclose herein are separated and/or processed materials obtainable by the method, articles-of-manufacturing comprising same, and systems for separating and/or processing the waste material.
