Wood Utilization

Forest landscape restoration is a widely accepted approach to sustainable forest management. In addition to revitalizing degraded sites, forest landscape restoration can increase the supply of sustainable timber and thereby reduce logging in natural forests. The current study presents a spatial land use optimization model and utilizes a linear programming algorithm that integrates timber production and timber processing chains to meet timber demand trade-offs and timber supply. The objective is to maximize yield and profit from forest plantations under volatile timber demands. The model was parameterized for a case study in Thai Nguyen Province, Vietnam, where most forest plantations grow Acacia mangium (A. mangium). Data were obtained from field surveys on tree growth, as well as from questionnaires to collect social-economic information and determine the timber demand of local wood processing mills. The integration of land use and wood utilization approaches reduces the amount of land needed to maintain a sustainable timber supply and simultaneously leads to higher yields and profits from forest plantations. This forest management solution combines economic and timber yield aspects and promotes measures focused on economic sustainability and land resource efficiency.

Climate change, environmental degradation, and limited resources are motivations for sustainable forest management. Forests, the most abundant renewable resource on earth, used to make a wide variety of forest-based products for human consumption. To provide a scientific measure of a product’s sustainability and environmental performance, the life cycle assessment (LCA) method is used. This article provides a comprehensive review of environmental performances of forest-based products including traditional building products, emerging (mass-timber) building products and nanomaterials using attributional LCA. Across the supply chain, the product manufacturing life-cycle stage tends to have the largest environmental impacts. However, forest management activities and logistics tend to have the greatest economic impact. In addition, environmental trade-offs exist when regulating emissions as indicated by the latest traditional wood building product LCAs. Interpretation of these LCA results can guide new product development using biomaterials, future (mass) building systems and policy-making on mitigating climate change. Key challenges include handling of uncertainties in the supply chain and complex interactions of environment, material conversion, resource use for product production and quantifying the emissions released.

<p>Electricity production from biomass has the potential to significantly contribute to the share of renewable energy in the global power mix with lesser environmental impact than non-renewable resources. The production of bioenergy from forest biomass residues is currently increasing in Portugal, mainly as a consequence of concerns related to climate change and forest fires.  In Portugal, the annual production of residual biomass from forest logging is estimated at 0.8-1.2 million dry tons per year, and about 47-58% of these residues come from eucalypt. </p><p>This study evaluates the environmental impacts resulting from electricity production in Portugal using eucalypt logging residues (composed of branches, foliage and tops) and considering two types of technologies: grate furnaces and fluidised bed furnaces. This assessment was performed using life cycle assessment (LCA) methodology, a methodology that evaluates the environmental impacts entire life cycle of a product or process (from the extraction of the raw materials until its end-of-life), allowing to identify the most significant stages and processes along the life cycle, and supporting by this way the decision and policy-making.</p><p>Two alternative scenarios for biomass-to-energy conversion technologies were simulated: grate furnace and fluidised bed furnace. The functional unit is the production of electricity from the combustion of eucalypt logging residues equivalent to 1 kWh delivered by the power plant to the Portuguese grid. System boundaries include the following stages: (1) forest management (including site preparation, planting, stand tending and logging); (2) residues collection; and (3) energy conversion (including forest biomass combustion as well as treatment and final destination of wastes). Seven impact categories from the International Reference Life Cycle Data System (ILCD) are considered: climate change, particulate matter, photochemical ozone formation, acidification, freshwater eutrophication, marine eutrophication and mineral and fossil resource depletion.</p><p>The results show that the forest management stage had a low contribution to the total impact in all impact categories for both technologies under analysis. The only exception is the impact category of mineral and fossil depletion, in which forest management is mainly responsible and which accounts for 92-94% of the total impact for both technologies analysed. The energy conversion is the hotspot in most of the impacts studied (climate change —49-63%, particulate matter —94-95%, photochemical ozone formation —85-88% of, acidification —76-79%, freshwater eutrophication —56-58% and marine eutrophication —70-71% of the total impact) and therefore, this is the stage for which improvements should be primarily establishedestablished for both technologies analysed. In addition, for all impact categories analysed, the fluidised bed presented the smallest environmental impact. Even when the grate furnace efficiency increases and the fluidised bed efficiency decreases in a sensitivity analysis, the fluidised bed has lower impacts than the grate furnace and is a good alternative for implementing new power plants. Further research is needed to analyse the effects of converting the grate technology in Portugal to fluidised bed technology.</p>

In the 1970s an outbreak of spruce budworm, combined with rising protection costs, environmental concerns, and recoghition of the long-term nature of the infestation, demanded new approaches to forest management and protection. Through adapting traditional policy, frequent conflict and innovation, the Maine Department of Conservation and private landownes refined their understanding of the budworm infestation as a long-term management problem. The recently completed Maine Spruce-Fir Wood Suply/Demand Analysis highlighted the need for investment in more intensive forest management and better wood utilization, in addition to continued protection, if Maine's industries dependent on spruce and fir are to maintain their current levels of production.

Strategic Fit

Unsustainable forest management is considered as one of activities that leads to forest degradation. Together with deforestation, degraded forests are contributors to the greenhouse gas emissions from the forestry sector, so it needs to be controlled. Furthermore, degradation affects the forest’s productivity, and thus will affect the performance of the company which owns the licence for the utilization of its timber forest products. The objective of this research was to be able to identify aspects in Green Supply Chain Management and Life Cycle Assessment which are considered the most relevant to be applied in the management of degraded forest, and further to be structured in form of framework. The method used in this research is a qualitative approach with a case study PT XYZ as the holder of a Business License for the Utilization of Timber Forest Products in Natural Forest, in East Kalimantan. Research data obtained through literature studies, field observations, and interviews with key personnel in the company. Data is then analyzed through reduction and concluded. The results showed that internal supply chain activities, namely forest planning, forest development, log production, and marketing, play a significant role in the process of greening the supply chain. The proposed GSCM-LCA Framework includes Green Planning, Green Operations, Green Distributions, and Green Marketing with LCA observations focusing on evaluating and analysing environmental impacts caused by their harvesting and transportation activities. The design of the framework in this study emphasizes strategic-fit, as an effort to adjust the company resources and abilities towards the opportunities in the external environment.
