Tectona Grandis Teak
Tectona grandis Teak Family: Verbenaceae Other Common Names: Kyun (Burma), Teck (French). Teca (Spanish). Distribution: Native to India, Burma, Thailand, Indochina, including Indonesia, particularly Java. Extensively cultivated in plantations within its natural range as well as in tropical areas of Africa and Latin America.

Regulation on Forest Products Processing and Marketing
Forestry Development Authority Regulation No. 112-08 Regulation on the Forest Products Processing and Marketing WHEREAS, the National Forestry Reform Law of 2006 establishes a transparent framework, for the use, management and protection of forest resources that balances the commercial, community, and conservation priorities of the Republic; and WHEREAS, the economic potential of processed wood products has not been appreciated, there has been too much exportation of crude round logs with evidence of low percentage of primary processed wood for both domestic and export market, no value-added wood product, low recovery rate of wood processing industry, problem of waste disposal; and WHEREAS, industrialization of the wood industry in general and the processing of wood into secondary/value-added products in particular are essential elements for the realization of the potential sustainable utilization of Liberia‘s forest resources; and WHEREAS, sustainable utilization of forest resources concept is not only to maintain the value of forest resources, but rather it also has a huge potential for creating employment, income and wealth for the Liberia populations; and WHEREAS, local small-scale wood enterprises are not fully capacitated and unregulated which in essence has resulted into unsustainable use and marketing of wood products, wastage of wood products, constant exposure of wood products to deteriorating agents; and WHEREAS, the lack of standard units of measurement for Liberia domestic wood market and unregulated import of wood products, -

PEER-REVIEWED ARTICLE bioresources.com EVALUATION AND IDENTIFICATION OF WALNUT HEARTWOOD EXTRACTIVES FOR PROTECTION OF POPLAR WOOD Seyyed Khalil Hosseini Hashemi a,* and Ahmad Jahan Latibari a Walnut (Juglans regia L.) heartwood extractives were identified and their potential for protection of poplar wood was evaluated. Test specimens were prepared from poplar wood (Populus nigra L.) to meet BS 838:1961 requirements. Samples were impregnated with heartwood extractive solution (1.5, 2.5, and 3.5% w/w in ethanol-toluene), followed by 5 hours vacuum desiccator technique to reach complete saturation. Impregnated specimens were exposed to white-rot fungus (Trametes versicolor) for 14 weeks according to BS 838:1961 applying the kolle- flask method. The weight loss of samples was determined after exposure to white-rot fungus. The highest weight loss (36.96%) was observed for untreated control samples and the lowest weight loss (30.40%) was measured in samples treated with 1.5% extractives solution. The analyses of the extracts using GC/MS indicated that major constituents are benzoic acid,3,4,5-tri(hydroxyl) and gallic acid (44.57 %). The two toxic components in the heartwood are juglone (5.15 %) and 2,7- dimethylphenantheren (5.81 %).

Energy Efficiency Measures in the Wood Manufacturing Industry
Energy Efficiency Measures in the Wood Manufacturing Industry B. Gopalakrishnan, A. Mate, Y. Mardikar, D.P. Gupta and R.W. Plummer, West Virginia University, Industrial Assessment Center B. Anderson, West Virginia University, Division of Forestry ABSTRACT The objectives of the research are to examine the energy utilization profile of the wood manufacturing industry with respect to system level production parameters and investigate the viability of specific energy efficiency measures. The Industrial Assessment Center (IAC) has conducted energy assessments in the wood manufacturing industrial sector in the State for several years. The energy utilization profile of several wood processing facilities is analyzed and reported. The production system parameters in terms of throughput and nature of manufacturing operations are examined in relation to the overall energy utilization, specific energy consumption, and potential for implementation of energy efficiency measures (EEM). Introduction Energy management is the application of engineering principles to the control of energy costs at a facility. It is a continuous process that requires consistent efforts for identifying potential areas for conservation, formulation of proposals and implementation. There are many energy efficient technologies and practices, both currently available and under development, that could save energy if adopted by industry. Energy and energy management have been in the limelight in various manufacturing and service operations across the industries in the US. Although large quantities of wood are utilized as fuel, pulpwood, and railroad ties, lumber is by far the most important form in which wood is used. In the US, the volume of wood converted into lumber exceeds the volume used for all other purposes. -

This has led to many of the tropical forests viable alternative in many of WWF’s priority places. being plundered for these highly prized species. Even in forests where there are good levels of forest management, there is a risk of a shift in species composition Markets are hard to change, as buyers from consumer countries often aren’t in natural forest stands. This over-exploitation can also dissuade many forest willing to switch from purchasing the traditional species which they know do managers from obtaining Forest Stewardship Council (FSC) certification for the job for the products that they are used in, and for which there is already their concessions, as many of these high value species are rarely available in a healthy market. To enable the market for LKTS, there is an urgent need to sufficient quantity to cover all of the associated costs of certification.
