  • Patent number: 4225640
    Abstract: A method of reclaiming thermoplastic material from municipal waste wherein the thermoplastic material is separated from the municipal waste and is decimated into fragments which are of a size to pass through a screen of a predetermined mesh, for example a mesh with one-half inch openings. Similarly, fallen leaves are kept segregated from other municipal waste and are shredded or similarly decimated so that they may pass through a screen having a predetermined mesh, for example of a mesh comparable to that through which the plastic must pass. The fragments of thermoplastic material and the leaf fragments are blended so as to be thoroughly intermixed, subjected to sufficient heat and pressure so that the thermoplastic material may coat and bond to the surfaces of the leaf fragments and form a unitary mass of leaf fragments and plastic material. The consolidated mass of leaves bonded by the thermoplastic material is then permitted to set and cure so as to be formed into any desired shape.
