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 ....

T field of forest products is a blend of several subjects—forestry, biology, chemistry, and engineering, among many others. This blending can at times lead to communication gaps between disciplines and create confusion for consumers. Inaccuracies can lead to the inappropriate utilization of wood, shortening its service life, or worse, creating safety hazards. It is therefore pertinent for users...

BACKGROUND The objective of this study was to demonstrate a new, cost-effective method to define the sustainable amounts of harvested wood products in Southeast Asian countries case studies, while avoiding degradation (net loss) of total wood carbon stocks. Satellite remote sensing from the MODIS sensor was used in the CASA (Carnegie Ames Stanford Approach) carbon cycle model to map forest prod...

From time to time, wood plays an important role in solving criminal cases. Wood samples vary in size and can range from trees and logs to pieces as small as individual wood fibers. Botanists can easily identify trees. especially when the leaves, flowers. or fruits are present. Using standard techniques. wood technologists. foresters, and wood anatomists can generally identify logs, lumber, wood...

Forest certification is a voluntary verification tool that has been gaining importance within the global sustainability issues as an independent verification tool for sustainable forest management and wood processing industry and as an influencer in private and public purchasing policies and a component of emerging wood harvesting and trade legality schemes. This study focuses on the chain-of-c...

This chapter describes the development of material-specific estimates of changes in forest carbon storage in EPA's Waste Reduction Model (WARM). It summarizes the approach used to estimate changes in forest carbon storage in managed forests resulting from source reduction and recycling of wood and paper products. Forests absorb (i.e., sequester) atmospheric carbon dioxide (CO 2) and store it in...

■ Carbon storage in forests. In one study, taking “no action” rather than harvesting stored more carbon. ■ Carbon storage considering forests, wood products, and concrete substitution. Collectively a 45-year harvest cycle, wood products and substitution for non-wood products stored more carbon than the “no action” managed forest scenario. ■ Carbon storage in houses. Wood-framed houses store mor...

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...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...
