ECONOMIC FEASIBILITY OF PROCESS FOR HIGH-YIELD LAMINATED STRUCTURAL PRODUCTS

Recovery of lumber-type products from sawlogs can be substantially greater than that by conventional sawing processes if veneer-product production methods are used. Economic analysis based on a hypothetical continous-process veneer-product facility derives production costs of acceptable levels for producing high-strength and specialty lumber-type products. Continous laminating presses suitable for the facility evaluated are not yet commercially available but can be replaced with batch laminating presses for producing short-length products such as crossarms and railroad crossties. Methods may be developed to reduce glue costs. Increasing log prices will also increase the economic advantage of high-yield laminating processes. (Author)
