Valuable product production from wood mill effluents.
Fibreboard production is one of the most important industrial activities in Galicia (Spain). Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final product and water reusing, among others. These effluents are characterized by a high chemical oxygen demand (COD), low pH and nutrients limitation. Aerobic and anaerobic processes have been...
متن کاملComparing Life-Cycle Carbon and Energy Impacts for Biofuel, Wood Product, and Forest Management Alternatives*
The different uses of wood result in a hierarchy of carbon and energy impacts that can be characterized by their efficiency in displacing carbon emissions and/or in displacing fossil energy imports, both being current national objectives. When waste wood is used for biofuels (forest or mill residuals and thinnings) fossil fuels and their emissions are reduced without significant land use change...
متن کاملMeasurement of Wood Stiffness in Standing Trees and Logs: Implications for End-Product Quality
At present, mills producing structural timber generally undertake strength grading at the end of the production process, i.e., after buying the material and sawing it into timber which is then dried. This means that any variation in wood stiffness between forest stands and between trees is unknown and unaccounted for until the end of the manufacturing process. Portable stress-wavebased tools pr...
متن کاملNew species of wood inhabiting discomycetes of Helotilaes for Iran
Four species of wood inhabiting cup fungi belonging to order Helotiales are reported for the first time in Iran. Species are described and illustrated with photographs and drawings. Three genera Arachnopeziza, Hymenoscyphus and Lachnum are new records for Iran.
متن کاملAsteroidal number for some product graphs
The notion of Asteroidal triples was introduced by Lekkerkerker and Boland [6]. D.G.Corneil and others [2], Ekkehard Kohler [3] further investigated asteroidal triples. Walter generalized the concept of asteroidal triples to asteroidal sets [8]. Further study was carried out by Haiko Muller [4]. In this paper we find asteroidal numbers for Direct product of cycles, Direct product of path and cy...
