Explanation and Instructions

"Dividends From Wood Research" is a semiannual listing of recent publications resulting from wood utilization research at the Forest Products Laboratory (FPL). These publications are produced to encourage and facilitate application of Forest Service research. This issue lists publications received between July 1 and December 31, 2005.

Each publication listed in this brochure is available through at least one of the following sources.

Available from FPL (indicated by an order number before the title of the publication): Quantities limited. Order by sending the item number and your complete mailing address.

Available through Internet: Listed publications are available as PDF documents for viewing or printing through links provided in this document.

Available through sales outlets: Major sales outlets are the Superintendent of Documents, the National Technical Information Service (NTIS), and various private publishers. Order directly from the outlet.

Available through libraries: Research publications are available through many public and university libraries in the United States and elsewhere. U.S. Government publications are also available through many Government Depository Libraries. Check with a major library near you to determine availability.

Decay Processes and Bioprocessing

Durability

For international trade, heat sterilization of wood products is often required to prevent the spread of insects and pathogens. Application of heat sterilization requires estimates of the time necessary to heat the center of the wood configuration to the temperature required to kill the insect or other pest. The nature of the heating medium was found to have a significant effect on heating time of slash pine lumber. The heating time increased exponentially with wet bulb depression. When the wet bulb temperature in the heating chamber was below the desired center temperature, heating times were extended far beyond the times when target center temperature was greater than the wet bulb temperature. This effect was less in air-dried lumber than in green lumber.

General

Controlling erosion is a serious and challenging task. Annually, erosion is responsible for billions of dollars of damage worldwide. Erosion control mats (ECMs) were developed to control erosion and provide soil stability until vegetation can be established. There are hundreds of products in the erosion control market. Erosion control mats are made from organic materials, synthetic materials, and sometimes a combination of the two. This report is a market analysis of ECMs based on a telephone survey of nine manufacturers and a literature search. The objective of the market analysis was to provide background information and to summarize the ECM industry. The objective of the telephone survey was to determine information about ECMs such as the price, mode of promotion and distribution, most popular product, and current demand and growth potential. The product background section provides a brief description of the most popular types of ECMs. The analysis focuses on the market history, major competitors, major consumers, market size, demand and growth, and the results of a telephone survey. Thirty-eight major competitors were found as well as several major consumers. The telephone survey provided information on current trends in pricing, promotion, and distribution; popular ECM types; and major consumers. The market analysis determined that the market for ECMs will grow, based on the fact that the world population is projected to increase, therefore increasing construction of buildings and roads. Also, the fact that some ECMs are made with natural products instead of synthetic products helps them win acceptance in public opinion.

Timber and Fiber Demand and Technology Assessment

From a starting universe of approximately 1,300 Canadian and American sawmills, 149 were permanently closed between 1996 and 2003. This figure does not include small portable or part-time operations. These mills represented 17.6 million m3 of capacity, nearly 12% of the 1995 industry total. On the other hand, 25 new mills brought on-line have offset 4.9 million m3 of lost production potential. Further, upgrades to existing sawmills have added 31 million m3 of capacity. The region most severely impacted by closures was the U.S. West, which accounted for over half of all the capacity lost. Other regions fared better, with the U.S. South and eastern Canada losing the least, the U.S. North and British Columbia taking somewhat higher losses. Overall, however, each major producing region gained capacity when all changes are accounted for.
