Adhesives have played and will continue to play an important role in the efficient utilization of wood resources. Early Egyptians used adhesives to attach rare veneers to wood furniture. Today, adhesives play a vital role in allowing almost all types and sizes of wood to be converted to functional products. For centuries, wood was bonded using biobased adhesives. In the 20th century, synthetic ...
This paper describes the analysis of raw wood flows in Slovakia. Material flow analysis was used to reveal and quantify relations between the resources and the primary uses of wood. In particular, two approaches to wood flow modelling were utilised wood balance and wood resource balance. Wood balance was introduced to illustrate a global view of the resources and primary uses of roundwood in Sl...
Mycelial development of Phanerochaete velutina extending from wood inocula in 57 x 57 cm trays of non-sterile soil was characterized after adding: (1) collembola; (2) new wood resources; (3) both new wood resources and collembola; and (4) no new resources and no collembola. After 99 d, all systems had produced distinct mycelial cords, much of the diffuse mycelium and thinner cords that were pro...
As one of the most important renewable and sustainable energy sources, the forest biomass energy resource has always been the focus of attention of scholars and policy makers. However, its potential is still uncertain in China, especially with respect to its spatial distribution. In this paper, the quantity and distribution of Chinese forest biomass energy resources are explored based mainly on...
Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...
lignocellulosic resources of khoozestan province are usable for wood and paper industry. the main questions are that, which places have the best conditions are select for development of wood and paper industries? since, the methodologies of research were analytical and estimated. the research questions were tested by method of analytic hierarchy process (ahp). the results of the research were s...
the deficiency of wooden resources and rising demand of wood and paper products caused an increasing interest to the lignocellulose resources in the production of paper and wood composite production, such as bagasse. in khuzestan province for build units of wood and paper industries with the approach of using bagasse as a raw material, 6 main indicator and 35 sub-indicator were prioritization. ...
The earthquake had hit Muzaffarabad on October 8, 2005. Being one of the dreadful events, it badly devastated the area. In addition, the post earthquake scenario raised fears of pressure on forestry resources, especially for reconstruction phase. It was, therefore, essential to assess the availability of salvage wood to prevent/or reduce the pressure on forestry resources. Thus, the study was l...
