| Summary |
"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)." |
