Method for recycling synthetic wood materials from sheathing board for use in a concrete form formed by synthetic wood materials, and sheathing board for use in a concrete form having the previously mentioned recycled synthetic wood materials as raw materials

Abstract

There is provided a method for recycling synthetic wood materials, transformed into materials through a relatively simple method without performing elimination of encrusted concrete from a previously used sheathing board for use in a concrete form having synthetic wood materials as raw materials. The method consists of a step wherein a sheathing board() which had been previously used as a concrete formand formed from synthetic wood materials with a moisture content of less than 15 wt %, wherein between 20 and 75 wt % of cellulose crushed materials, such as wood meal with particle diameters of between 50 and 200 μm, and between 25 and 80 wt % of thermoplastic resin molding materials, are mixed, is crushed into numerous coated particles, and a step wherein a scraping impact force is applied to each individual coated particle, concrete and other encrusted materials encrusted on the previously mentioned coated particlesare peeled or separated, and at the same time as the synthetic wood materials constituting the coated particlesand the encrusted materials are classified, the particles of the synthetic wood materials are granulated, and the granulated synthetic wood meal materialsfor which the particles have been granulated are recycled.
