Norbord is buying up wood burned by the Gustafsen wildfire. A local logging contractor, Rod Dillman, is the first to begin harvesting in the Gustafsen fire area, says Mike Kennedy, Woodlands Manager with Norbord in an email. He adds that there are some unique challenges logging burned wood.
“According to Rod, a primary challenge in logging the burned wood is the increased maintenance needed on his machines. There is a lot of ash dust which, even more than ‘normal’ dirt, tends to stick to surfaces and must be washed off rather than just wiped. It also makes it necessary to change air filters more frequently. Finally, carbon in the ash is hard on the knives used in the harvesting equipment. Rod also states that they are learning as they go, as this is the first time he has operated in such a large area of scorched timber.”
Kennedy says that luckily there are a few things that have moderated the effect of the fires on the trees, meaning most of the wood is still intact underneath the bark. “Certain species, for example, Douglas-fir with its thick bark, have evolved to withstand the effects of fire, which is a common natural event in the areas where it grows. Fire intensity was not uniform across the landscape, so in many places, trees were scorched on the bark only with minimal damage to the underlying wood. Entire trees are not necessarily affected, with more damage occurring in the bottom portion. It is often possible to buck this out with log processors at the roadside. Processing pressure can be increased to remove most of the severely burned bark or wood.”
They take pride in their adaptability to make the most of the fiber available and are very experienced using dry pine beetle killed wood, he says. “Norbord maintains the highest quality standards for our products and these standards are ensured through third-party certification by APA – The Engineered Wood Association. We have been able to use burned wood in the past.”

Wood has a largely favorable environmental effect. A study of the National Research Programme “Resource Wood” recommends using wood more widely as a source of energy and as a building material.
The study examined the overall environmental impact of wood in Switzerland, analyzing the value chain from cutting trees to recycling wood or burning it, including the manufacture of semi-finished products such as paper, boards and pellets for heating purposes. Wood manufacturing is a high profile industry in Switzerland, home to suppliers familiar in the U.S. such as IGP power coating, Michael Weinig machinery, Jowat adhesives, Swiss Chrono laminate panel, and Lamello.
The study indicates that the sustainable use of wood can contribute to meeting our needs in terms of energy and raw materials with a smaller footprint than other resources.
The study estimates that the use of wood in Switzerland leads to a reduction in CO2 emissions of between 2.0 and 3.1 million tons per year – in comparison, Switzerland emitted a total of 52.6 million tons in 2013. Replacing gas or oil with wood accounts for two thirds of the estimated reduction. The last third is linked to construction and furniture production where wood replaces materials with a high carbon footprint such as cement, steel, aluminum and plastics.
Conducted in the context of the National Research Programme “Resource Wood” (NRP 66), the study based its analysis on the one hand on comprehensive statistics of material flows (origin, use and disposal of wood) that were compiled by the federal offices in particular. On the other hand, it referred to several databases evaluating the life cycle of products. “We considered different environmental impacts, in particular in relation to climate change, energy consumption, air pollution and loss of biodiversity”, explains Florian Suter, first author of the study and doctoral student at the Chair of Ecological Systems Design at ETH Zurich.

Last month we saw cross-laminated timbers installed at the Albina Yard project in Portland. It was the first use of U.S.-produced CLT in a building-wide structural system.
The first level of CLT (4,000 square feet) on Albina Yard went up in fewer than four hours. Last week, the second level was installed by a crew of seven in under two hours. Pretty remarkable, considering the contractor says it would have taken at least twice as many people two days or more to frame the same amount of floor space using traditional methods. Albina Yard is a four-story, 16,000-square-foot creative office project in north Portland. Besides its snazzy design by LEVER Architecture, the project is most notable for being tangible evidence that the U.S. CLT industry is officially off the ground.
There’s been a lot of buzz around CLT and mass timber in general over the past several months in Oregon and around the country — and rightly so. Besides drastically improved speed of construction (and the savings that go with that), mass timber offers significant environmental benefits. This includes tremendous carbon-storing capacity. Half the dry weight of wood is carbon. It got there when the trees were growing and absorbing carbon dioxide from the atmosphere. That carbon remains locked up for as long as the wood remains in use (a nine-story wood structure in China is now 959 years old—nearly a millennium). The new trees planted to replace those that were harvested start the carbon cycle all over again.
According to a quick, back-of-the-napkin calculation, Albina Yard, which is small by commercial construction standards, stores about 80.5 metric tons of carbon. That’s equivalent to offsetting 295 metric tons of CO2 emissions.
A larger Portland mass timber building, Clay Creative (60,000 square feet), stores more than 1 million pounds of carbon. Its total of 457.5 metric tons offsets 1,678 metric tons of CO2 emissions. “An additional 3,574 metric tons of CO2 emissions were avoided by using wood rather than concrete and steel,” says Dr. Jim Bowyer, an expert on the subject at Dovetail Partners, Inc.

Oregon and southwest Washington make up one of 12 new regions accepted into the Investing in Manufacturing Communities Partnership initiative. The program is a federal effort to increase domestic manufacturing by “supporting the development of coordinated, long-term economic development strategies in communities,” according to Business Oregon.
The U.S. Department of Commerce selected the regions based on competitive proposals. The first 12 regions were accepted last year and the Pacific Northwest was not among them. U.S. Commerce Secretary Penny Prtizker said the initiative is critical to the administration’s efforts. “To support American manufacturing, create good paying jobs and spur sustainable growth across our country,” she said. She said the designation is an important positive signal to potential investors in the Northwest and other parts of the country.
The Pacific Northwest Partnership Region will focus on reviving and modernizing the timber industry. Cross-laminated timbers (CLT), a type of cross-hatched wood product, are as strong as steel or concrete and will be manufactured locally under the program.
On its website, Business Oregon says cross-laminated timbers have “significantly lower environmental impact, sequesters carbon and yet meets the same fire and safety code regulations as concrete and steel.” The new type of wood can even be used to frame skyscrapers.

The American Wood Council has been awarded a $250,000 grant from the U.S. Department of Agriculture (USDA) to conduct research on the fire performance of mass timber buildings. AWC will partner with the National Fire Protection Association’s (NFPA) Fire Protection Research Foundation and the Property Insurance Research Group.
The AWC proposal is intended to advance the construction of taller wood buildings in the United States by demonstrating the fire performance of newer mass timber products. Over the last several years, tall wood buildings have been completed around the world using this new technology – including a 9-story building in London, 10-story in Prince George, Canada, and 14-story building now under construction in Bergen, Norway. These buildings have consistently demonstrated the successful application of mass timber technologies.
“Findings from this project will inform the building community and the insurance industry, providing an increased level of confidence in both the adequacy of this new construction type and when setting fire insurance premiums. This is a new method of construction to insurers, and in order to provide reasonable insurance coverage, they need to understand the performance of the material,” said AWC Vice President of Codes & Regulations Kenneth Bland. Increased use of wood in building construction also holds great promise for improved environmental impacts.
“Innovative mass timber wood products encourage sustainable forestry and capture large amounts of carbon, thereby reducing greenhouse emissions through both sequestration and the substitution of wood for more carbon-intensive products. The construction of tall wood buildings would put America at the forefront of an emerging global opportunity,” said AWC President & CEO Robert Glowinski.
When announcing the USDA 2015 Wood Innovations grant recipients, Agriculture Secretary Tom Vilsack said, “Working with our partners, the Forest Service is promoting deployment of new technologies, designed to support new market opportunities for wood energy and innovative wood building materials.”
