This book was released on 2021 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is facing severe challenges from climate change and resource scarcity caused by exponential growth in population and the rising standard of living. Raw materials for buildings and construction account for more than 35% of global primary energy use and nearly 40% of energy-relatedCO2 emissions. The public as well as city, state, and national governments are interested in knowing the environmental impacts of materials including wood products. This study conducted a cradle-to-gate life-cycle assessment (LCA) of laminated strand lumber (LSL)production in North America (United States and Canada).System boundaries in this study included the following information modules: raw material extraction (A1), raw material transportation (A2), and product manufacturing(A3). Module A1 included forest resources and resin production. The declared unit was 1 m3 of LSL packaged and ready for shipment. Surveys were used to collect primary LSL production data. This LCA study followed the guidelines of the International Organization for Standardization standards and wood products product category rules. The tool for the reduction and assessment of chemical and other environmental impacts (TRACI), CML baseline, and cumulative energy demand were used to conduct a life-cycle impact assessment. The weighted average oven-dried density of LSL was 647 kg/m3. Results showed that about 275 kg CO2eq (A1–A3) were released in the production of 1 m3 of LSL, with the A1 life-cycle stage accounting for 56%, followed by A3 (23%) and A2 (21%). Resin production contributed 124 kg/CO2eq (45%), which isa substantial portion. Raw material extraction (A1), resource transport (A2), and LSL manufacturing (A3) consumed about 26%, 6%, and 68% of total cradle-to-gate primary energy, respectively. About 56% of the total primary energy used in the production of LSL (A1–A3) came from non renewables, mostly fossil resources. One cubic meter of LSL stores 1,150 kg CO2eq, which is about four times more than the embodied carbon released from cradle to gate(275 kg CO2eq).
Download or read book Cradle to Gate Life Cycle Assessment of Softwood Lumber Production from the Northeast North Central written by Maureen Puettmann and published by . This book was released on 2013 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: "CORRIM, the Consortium for Research on Renewable Industrial Materials, has derived life cycle inventory (LCI) data for major wood products and wood production regions in the United States. The life cycle inventory data cover from forest regeneration through to final product at the mill gate. Research has covered nine major forest products including both structural and nonstructural uses and four major regions: in this report we focus on planed dry softwood lumber produced in the US Northeast-North central (NE-NC) region. The NE-NC regional data is a representative cross-section of forest growth and manufacturing processes in 20 states. Due to little or no production 6 states have been omitted: Connecticut, Delaware, Illinois, Iowa, New Jersey, and Ohio. This document updates the current wood product LCIs from a gate to gate to a cradle to gate LCI. Updates include the addition of NE-NC forestry operations, boiler, and electrical grid that have been developed since the original mill surveys were conducted in the years 1999 and 2000. The updated LCI data were used to conduct life cycle impact assessments (LCIA) using the North American impact method, TRACI 2.0 (Simapro version 4.0)(Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts) (Bare et al. 2011). These updates are necessary for the development of environmental product declarations (EPD) which will be based on this document. This document originates from the CORRIM LCI reports by Bergman and Bowe (2009, 2010) and Oneil et al. (2010). Updates in this report from the original Bergman report include: wood combustion boiler updates, electricity grid updates (Goemans 2010), and an LCIA. Updates to the forestry operations report include electricity grid updates and an LCIA using the TRACI method. This report follows data and reporting requirements as outlined in the Product Category Rules (PCR) for North American Structural and Architectural Wood Products (PCR 2011) that will provide the guidance for preparation of North American wood product EPD. This report does not include comparative assertions.S3.

Download or read book A Life Cycle Assessment of Hardwood Lumber Production in the Northeast and North Central United States written by and published by . This book was released on 2020 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This life cycle assessment is part of a larger project to update the life cycle inventories for major wood products produced in the United States (U.S.) on a five-year cycle. Hardwood lumber manufacturing data were collected for the 2017 production year from sawmills operating in the northeast and north central regions (NE/NC) of the U.S.A life cycle inventory (LCI) of hardwood lumber production in this region was conducted for the production year 2005 (Bergman and Bowe 2008a). The updated LCI data collected for this study were used to conduct a life cycle impact assessment (LCIA) using the North American impact method, TRACI2.1 (Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts) (Bare 2011).This work provides information necessary for subsequent environmental product declarations (EPDs). As such, this report follows the requirements outlined in Product Category Rules (PCR) for North American Structural and Architectural Wood Products (ULE 2019) and American Center for Life Cycle Assessment(2019). The report builds on previous studies (Bergman and Bowe 2008b, Puettmann et al. 2010) and reports LCIA results for mass allocation to produce 1.0 m3 of planed, kiln-dry, hardwood lumber.

Available in PDF, EPUB and Kindle. Book excerpt: Because of environmental awareness and regulations and the advent of environmental preferential purchasing, documenting the environmental profiles of building products using life-cycle assessment (LCA) has become a widespread emergent global trend. This study conducted a cradle-to-gate LCA of hardwood lumber production in the southeastern United States. System boundaries in this study included the following production stage information modules: raw material extraction (A1), resource and material transportation (A2), and hardwood lumber manufacturing (A3). Module A1 included forest management activities. The declared unit was 1 m3 of hardwood lumber packaged and ready for shipment. Surveys were used to collect primary hardwood lumber production data. This LCA study followed the standards of the International Organization for Standardization and the wood products product category rules. The tool for the reduction and assessment of chemical and other environmental impacts (TRACI), CML baseline, and cumulative energy demand were used to conduct a life-cycle impact assessment. The weighted average oven-dried density of southeastern hardwood lumber was 576 kg/m3. Results showed that about 209 kg CO2eq were released in the production of 1 m3 of hardwood lumber (all information modules combined), with the A3 module accounting for 71%, followed by A1 (15%) and then A2 (14%). Raw material extraction (A1), resource and material transportation (A2), and hardwood lumber manufacturing (A3) consumed about 9%, 7%, and 84%, respectively, of total cradle-to-gate primary energy. About 59% of the total primary energy used in the production of hardwood lumber (A1–A3) came from nonrenewable, mostly fossil, resources. One cubic meter of southeastern hardwood lumber stores 1,055 kg CO2eq, which is about four times more than the embodied carbon released from all three modules of the production of this lumber (209 kg CO2eq).

Available in PDF, EPUB and Kindle. Book excerpt: Under the assumption that forests are sustainably managed, and therefore the forest itself is neither a carbon source or a carbon sink, a LCA was undertaken to quantify the environmental footprint of redwood decking produced and sold in western North America. The goal of the study was to quantify the environmental impacts of redwood decking production and use over a 25 year life span in what is known as a cradle to grave LCA. The results were used to compare the environmental footprint of redwood decking to plastic (cellular PVC) and wood-plastic composite (WPC) decking as the two dominant competing products in the residential decking market in western North America.
