Book CORRIM Report

Download or read book CORRIM Report written by Richard Bergman and published by . This book was released on 2020 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental consequences of producing a material such as laminated veneer lumber (LVL) are carried forward into the life cycle of products such as wooden structures. CORRIM, the Consortium for Research on Renewable Industrial Materials, has derived life cycle inventory (LCI) data for major wood products manufactured in several regions of 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, both structural and nonstructural, and four major regions: in this report we focus on LVL produced in the US southeast (SE) region. This report describes the energy and materials for producing LVL in the SE region of the US through a cradle-to-gate life cycle inventory on the manufacturing process. The environmental impacts, global warming, ozone depletion, acidification, smog, and eutrophication are discussed. The focus of this report is an industry average LVL production in the SE region of the United States. LCI data are then used to estimate life-cycle impact assessments (LCIA). This study updates the cradle- togate manufacturing for LVL in the SE (Dancer and Wilson 2004, Wilson and Dancer 2005)

Book Life Cycle Inventory of Laminated Veneer Lumber and Composite I joist Manufacturing

Download or read book Life Cycle Inventory of Laminated Veneer Lumber and Composite I joist Manufacturing written by Eric R. Dancer and published by . This book was released on 2003 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to complete life cycle inventories (LCI) for laminated veneer lumber (LVL) and composite I-joist (I-joist) production in the two main forest products producing regions in the U.S., the Pacific Northwest (PNW) and Southeast (SE). LVL and I-joists are composite wood building materials that are commonly used for residential and light commercial construction. LVL is used as a replacement for structural lumber and is made from wood veneer. I-joists are most commonly used as replacements for structural lumber in floor and roof systems. The primary objective of the LCI is to gather data to measure all aspects of the material, energy, and emissions inputs and outputs (Tibor, 1996). The LCI's were completed using SimaPro version 5.0.9 LCl/LCA software which is written by Pre' Consultants B.V. The LCI's were generated from both primary surveys, which were completed by the product manufacturers, and secondary data from external sources. These sources included, the United States Department of Energy (USDOE), The Franklin Associates (FAL), ATHENATM (ATHENA, 1997). The LCI data is being compiled for the Consortium for Research on Renewable Industrial Materials (CORRIM). The inputs in the LCI analysis include wood inputs, fuel, energy, electricity, and resin. Outputs include the finished product as well as co-products and all air, land, and water emissions. The LCI data from all phases of the wood products industry will be compiled into a life cycle assessment (LCA) for the larger CORRIM project. The primary research data was obtained from manufacturing facilities in each region representing a significant portion of the total production for each region. Additional work was done to complete a carbon balance, cost analysis, and scenario analyses for production in each region. The results of this data will be used to evaluate the environmental performance of producing these products in each region. Special emphasis is placed on areas within the production process that have the largest impact on emissions. These areas will be examined to determine if the system can be made more efficient or if emissions can be reduced. The data shows that the largest sources of emissions come from the production of veneer and resin. The other major sources of emissions come from the production and use of fossil fuels and electricity. Reduction in the amount of resin used in the production of LVL shows significant reductions in the amount of certain key air emissions. In both LVL and I-joist manufacturing, the emissions generated at the plant were very small compared to the emissions generated in order to produce the input products and the fuels, energy, and electricity used at the plants.

Book Cradle to gate Life cycle Assessment of Laminated Strand Lumber Production

Download or read book Cradle to gate Life cycle Assessment of Laminated Strand Lumber Production written by Kamalakanta Sahoo and published by . 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).

Book Cradle to Gate Life Cycle Assessment of Softwood Lumber Production from the Northeast North Central

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.
