Abstract: A system and method is designed to recover and recycle waste lumber wood scrap products from construction sites and process this waste scrap lumber into lengths of recycled, usable lumber. The system processes "2.times.4" and to "2.times.6" lumber scraps from one or more construction sites and processes such material into recycled construction material in the form of finger jointed "2.times.4" and "2.times.6" lumber. The method and system accepts and utilizes random lengths of different species with different moisture contents. After the construction waste wood scrap products are delivered to a recovery site, unusable wood scrap products are removed. The usable products are processed by squaring the ends and cutting out defects; and the "2.times.4" sizes are separated from the "2.times.6" sizes.
