Abstract
Abstract This building component includes a peripheral sidewall and upper and lower walls forming a casing; a core of shredded waste material and an exterior plastic skin covering the casing. The method of making the component includes the steps of filling a peripheral form with shredded waste material, closing the form at the upper and lower ends incorporating it into the component by applying a reinforced plastic binder over the closed form.
