quantifying the greenhouse benefits of the use of Wood Products in two popular house designs in sydney australia
International Journal of Life Cycle Assessment, 2013Co-Authors: Fabiano Ximenes, Tim GrantAbstract:Purpose As the average Wood Products usage per unit of floor area in Australia has decreased significantly over time, there is potential for increased greenhouse gas (GHG) mitigation benefits through an increased use of Wood Products in buildings. This study determined the GHG outcomes of the extraction, manufacture, transport, use in construction, maintenance and disposal of Wood Products and other building materials for two popular house designs in Sydney, Australia.

The decomposition of Wood Products in landfills in Sydney, Australia.
Waste Management, 2008Co-Authors: Fabiano Ximenes, W.d. Gardner, Annette CowieAbstract:Three landfill sites that had been closed for 19, 29 and 46 years and had been operated under different management systems were excavated in Sydney. The mean moisture content of the Wood samples ranged from 41.6% to 66.8%. The Wood Products recovered were identified to species, and their carbon, cellulose, hemicellulose and lignin concentration were determined and compared to those of matched samples of the same species. No significant loss of dry mass was measured in Wood Products buried for 19 and 29 years, but where refuse had been buried for 46 years, the measured loss of carbon (as a percentage of dry biomass) was 8.7% for hardWoods and 9.1% for softWoods, equating to 18% and 17% of their original carbon content, respectively. The results indicate that published decomposition factors based on laboratory research significantly overestimate the decomposition of Wood Products in landfill.

Developing a Carbon Stocks and Flows Model for Australian Wood Products
Australian Forestry, 2007Co-Authors: Gary Richards, Chris Borough, David M.w. Evans, Ainslie Reddin, Fabiano Ximenes, David GardnerAbstract:Summary This paper describes the development of a model for estimating Australia's stocks and flows of carbon in harvested Wood Products, including estimates of atmospheric emissions. The model estimates emissions in various forms, including those from Wood Products contained in Australia, encompassing both domestically produced (net of exports) and imported Wood Products. This estimate is the basis of Australia's National Greenhouse Gas Inventory report on Wood Products. The model can also estimate emissions from all (and only) Wood Products produced in Australia, and a third variant that presumes emissions from Wood Products at the time of harvest. The model represents a collaborative effort, involving relevant Commonwealth and state government agencies, industry groups and research bodies. The model uses available statistics on log flows from forest harvest and estimates of the carbon content of the various Wood Products processed (for example, sawn timber, plyWood, pulp and paper and Woodchips) to det...

The contribution of Wood Products to carbon sequestration in Portugal
Annals of Forest Science, 2005Co-Authors: Ana Cláudia Dias, Margarida Louro, Luís Arroja, Isabel CapelaAbstract:SUMMARY Carbon sequestration in Wood Products, in Portugal, was estimated for the 1990-2000, using two accounting approaches: the stock-change approach and the atmospheric-flow approach. The results obtained with the two approaches indicate that Wood Products were a net sink of carbon throughout the studied period. A sensitivity analysis was also performed, showing that the results are significantly affected by the parameters related with the lifetime of the Wood Products (annual decay rates and fractions allocated to longlived Products), the carbon fraction in paper and paperboard and the biomass conversion factor of sawnWood and Wood-based panels.

The contribution of Wood Products to carbon sequestration in Portugal
Annals of Forest Science, 2005Co-Authors: Ana Cláudia Dias, Margarida Louro, Luís Arroja, Isabel CapelaAbstract:Carbon sequestration in Wood Products in Portugal was estimated for the 1990-2000 period using two accounting approaches: the stock-change and the atmospheric-flow. Calculations rely on historical data for production and trade of Wood Products, and on typical values for their lifetimes. Carbon sequestration in Wood Products, calculated by the stock-change approach, increased from 310 Gg C yr-1 in 1990 to 611 Gg C yr-1 in 2000. The estimates of carbon sequestration using the atmospheric-flow approach, in the same period, varied from 322 Gg C yr-1 to 783 Gg C yr-1, and do not show the same increasing trend given by the stock-change approach, as they depend not only on the change in the stocks of Wood Products but also on their trade. The sensitivity analysis performed shows that the results are significantly affected by the parameters related with the lifetime of the Products, the carbon fraction in paper and the biomass conversion factor.

innovation in large versus small companies insights from the us Wood Products industry
Management Decision, 2005Co-Authors: Ernesto R. Wagner, Eric N. HansenAbstract:Purpose – Aims to explain the effect of firm size on company innovation inside one industry context: the Wood Products industry.Design/methodology/approach – The strategic issues under study (innovation, corporate strategy) are typically managed by the firm's top executives. Also important is the fact that the response rates of questionnaires targeting this group are generally very low. Consistently, the data for the project were obtained from 43 in‐person interviews with top executives of Wood Products companies of different sizes in two countries, i.e. the USA and Chile.Findings – Finds that firm size does impact the innovation type pursued by companies, at least in the Wood Products industry. Indeed, large companies of this study clearly outrun smaller companies in process innovation. However, our analysis also shows that small companies level the field with larger companies when considering all three innovation types (process, product, business systems).Practical implications – The capital enjoyed by ...

Environmental attributes of Wood Products: Context and relevance for U.S. architects
Forest Products Journal, 2004Co-Authors: Ernesto R. Wagner, Eric N. HansenAbstract:Changing specifier preferences regarding the use and function of construction materials may greatly affect the consumption of Wood Products. Since architects are often involved in the selection of materials, they were selected for this research. A national survey of 1,200 architect office owners was conducted in order to investigate their environmental concerns and other design criteria regarding Wood Products. The study also identified the different degrees of effectiveness of several environmental actions taken by Wood Products companies. According to architects, the design attribute environmentally sustainable is of medium importance, regardless of the product group (the study defined three product groups: structural; appearance; and engineered Wood Products). Third-party environmental certification proved to be the most effective environmental action. Communication campaigns are surprisingly effective, suggesting that additional environmental advertising efforts by Wood Products companies might be beneficial. The results of the study suggest that advertising tailored to architects should have a dual purpose, stressing both a quality or appearance feature and an environmental one. Importantly, the quality or appearance issue changes depending on the product group. In that respect, uniform quality of the material is an important quality feature in both the structural and the engineered Wood product groups.
