This study characterizes a Portland cement based cellular system prepared with a preformed foam. Wood ash, locally sourced from pulp and paper mills, was first characterized and later, blended at up to 20% of the binder. The resulting mixtures were cast at three densities between 1000 and 1400 kg/m...

Every year, restoration programs in Southern Oregon and Northern California produce large amounts of low-value ponderosa pine, Pinus ponderosa (PP) lumber. This material has a limited market in the United States. Engineered wood products, such as cross-laminated timber (CLT) and glulam, are...

Governments have used policies such as taxes on the exports of unprocessed wood products and subsidies to domestic manufacturers to improve the competitiveness of domestic industries with the goal of supporting economic activities especially in rural areas. Newer motivations for policy...

Winch-assist or tethered logging technology is rapidly being adopted by the forest industry across the western United States to replace conventional and dangerous manual tree falling in cable logging areas. Although the safety benefits of the technology are widely acknowledged, the effects of...

Cross-sector collaboration is emphasized as a means for forest sector companies to remain competitive in a global marketplace that is evolving toward greater use of bio-based products (bioeconomy). Nevertheless, questions remain regarding how companies can identify and develop innovations via...

Oregon softwood log exports experienced a resurgence during years after the Great Recession. Using an empirically grounded partial equilibrium model, the purpose of this study is to assess the net effects of log exports on total economic surplus by measuring the effects of a hypothetical absence of ...

This study evaluates the environmental impacts of workable wood bio-concretes (WBC). The WBC is composed of wood shavings, Portland cement (CEM), and two Supplementary Cementitious Materials (SCMs): metakaolin (MK) and fly ash (FA). A Life Cycle Assessment (LCA) was performed on seven WBC mixtures...

We examine how forest taxation should be designed when tax revenues are used to finance expenditures on wildfire risk mitigation and when forest carbon storage has value. A model is solved sequentially in two stages by a forest tax planner and a representative private landowner. Our results show...

The number of mills and employees in Oregon's sawmill sector has continuously declined from 2003 to 2017, but the amount of lumber produced has stabilized in recent years. In this study, the performance of individual sawmills is evaluated by applying data envelopment analysis on a unique dataset...

This report traces the flow of Oregon's 2017 timber harvest through the primary wood products industry with detailed descriptions of the structure, timber use, operations, and condition of Oregon's industry. It is the fourth in a series of reports that periodically update the status of the...
