The objects consists of a mixture, which contains at least two types of material. One type may be one or more worthless waste products, which serve as constructional elements, whilst the second type may be one or more synthetic resins, serving as bonding elements. The synthetics may consist of acrylonitrile-butadiene styrene-, acrylo-nitrile styrene-, styrene, nylon-, vinyl chloride-, vinyls acetate-, acrylic melamine-, or polyester resins. The process produces pipes, rods, plates, etc. for constructional and building purposes, which are of high rigidity, wet- and corrosion proof, and manufactured at a very low cost due to the utilisation of waste products. |
