this study was accomplished in iran to investigate waste of common log sawing methods and to propose new sawing method. the old methods were performed due to difficulties on carrying logs out of forest. it seems necessary to change old methods due to development of sawmills and forest harvesting plans. the dimensions of wood products were collected to calculate the waste of old sawing methods ....

In wood trade, the supplier is the forest and the product is round wood. The quality, the quantity and value of wood depend heavily on the practices that are applied in the early stages of the supply chain. Current methods of the the productive capacity of forests, the annual consumption of wood and wood products, both from natural and technical forests and also from imports are presented. The ...

Micron-wood-fiber molded products are new kinds of high strength man-made wooden products. They are innovative products among molded fiber products nowadays. This paper studied a new method to design their screw joints using optimal design. It has combined the optimal design with reliability design ingeniously. The CAD programming method was put forward, which can optimize the structural parame...

With an evolving political environment of commitments to limit emissions of greenhouse gases, and of markets to trade in emissions permits, there is growing scientific, political, and economic need to accurately evaluate carbon (C) stocks and flows—especially those related to human activities. One component of the global carbon cycle that has been contentious is the stock of carbon that is phys...

10–1 Adhesive bonding of wood plays an increasing role in the forest products industry and is a key factor for efficiently utilizing our timber resource. The main use of adhesives is in the manufacture of building materials, including plywood, oriented strandboard, particleboard, fiberboard, structural composite lumber, doors, windows and frames, and factory-laminated wood products. Adhesives a...

Oregon State University • University of Idaho • Washington State University Wood has long served as one of our most versatile and heavily used raw materials. From it we derive solid wood for structural and ornamental applications, composite products in the forms of panels and beams, numerous paper products, chemicals, fuel—the list could go on and on. Foresters have worked for many years to inc...

The volume of CCA treated wood being disposed of in landfills is growing at an alarming rate. In order to reduce the demand on landfills and timber harvest, more environmentally responsible alternatives for spent CCA treated wood have to be addressed. The objective of this study was to determine feasible products that can be produced from CCA treated wood. Several products were produced from CC...

This paper examines the current wood tracking information systems used in international wood trade aiming to prevent and control illegally logged timber and wood products trade. Moreover, innovative log tracking mechanisms and technologies are also described and assessed. Wood tracking can add value to the wood product, by establishing an information system aiming to recognize and locate legal ...

wood and non-wood resources in the forests have occupied a very important place in human’s life, since the advent of history. and today, developing technology along with increasing needs enhance the importance of the other functions of forests, in parallel with wood production. both in the world and as well in turkey, one of the featured functions of forests is the production of non-woodforest ...
