A method for forming an article in which thermoplastics materials are used as the binding agent. Materials ( 21 ) are shredded in a shredder ( 1 ), compressed in a compressing chamber ( 15 ) and moulded in a moulding chamber ( 16, 17, 19, 20, 26, 27 ). The thermoplastics material is heated whilst the material is held under compression and then cooled to bind the material together. In one embodiment superheated steam is supplied via tubes ( 31 ) having apertures there along. In another embodiment superheated steam is supplied via apertures in side walls of the mould ( 58, 59 ). Blocks ( 62, 72 ) formed by the method and apparatus of the invention may find application as construction materials etc. and have good structural, thermal and acoustic properties. |
