Abstract

A cast recycled polyethylene product, optionally containing fibre reinforcement such as scrap polyester, contains oil as a compatibilizer. Typically the oil is derived from recycled containers. The product is made by comminuting containers, adjusting the oil content to the desired range, adding fibre reinforcement if desired, and heating the mix to a temperature sufficient for the polyethylene to commingle with the reinforcement if present, but insufficient to damage the fibers.
Typical cast products include guard rail posts, fence posts, highway median dividers, parking curbs, and the like. These products have the advantage of not being subject to weather damage and loss of structural strength, as is the case with timber and concrete.
