“…Nevertheless, overall system efficiency is increased if the feedstock energy value of the wood material is recovered at the very end. The duration time of the carbon storage of wood products is of minor importance if the end-of-life products are used to replace coal, which provides a permanent carbon emission avoidance, roughly equal to the carbon stock in the wood [64]. This will also depend on the efficiency of the biomass conversion plants, which is high in Scandinavia and comparable with fossil plants.…”

“…In this study, wood usage is compared to a reference scenario in which reinforced concrete is used as building material. Calculations are based on a case study of a multi-story apartment building constructed in Sweden using wood structural framing, compared to a functionally equivalent building constructed with a reinforced concrete frame (Gustavsson et al, 2006b). The comparison is made on a building level, and all materials composing the two buildings are included in the calculations.…”

Using biomass for climate change mitigation and oil use reduction

In this paper, we examine how an increased use of biomass could efficiently meet Swedish energy policy goals of reducing carbon dioxide (CO 2 ) emissions and oil use. In particular, we examine the trade-offs inherent when biomass use is intended to pursue multiple objectives. We set up four scenarios in which up to 400 PJ/year of additional biomass is prioritised to reduce CO 2 emissions, reduce oil use, simultaneously reduce both CO 2 emission and oil use, or to produce ethanol to replace gasoline. Technologies analysed for using the biomass include the production of electricity, heat, and transport fuels, and also as construction materials and other products. We find that optimising biomass use for a single objective (either CO 2 emission reduction or oil use reduction) results in high fulfilment of that single objective (17.4 Tg C/year and 350 PJ oil/year, respectively), at a monetary cost of 130-330 million h/year, but with low fulfilment of the other objective. A careful selection of biomass uses for combined benefits results in reductions of 12.6 Tg C/year and 230 PJ oil/year (72% and 67%, respectively, of the reductions achieved in the scenarios with single objectives), with a monetary benefit of 45 million h/ year. Prioritising for ethanol production gives the lowest CO 2 emissions reduction, intermediate oil use reduction, and the highest monetary cost. r

“…Increasing use of wood-based material could reduce the net GHG emissions because of the relatively low energy requirement during wood products manufacturing stage compared to conventional materials [6]. In addition, wood substitution in long-life-span wood products results in accumulated carbon storage [7].…”

Abstract. The use of wood is seen as a sustainable alternative to reduce environmental impacts in building and construction sector. The low quality hardwood logs from plantation thinning are enhanced by producing engineered wood such as laminated veneer lumber (LVL). Nevertheless, engineered wood requires the use of chemicals and energy that may reduce its environmental benefits. A life cycle assessment (LCA) was conducted to compare the environmental performance of LVL produced from forestry thinning and final harvest to steel and concrete. The functional unit used in this study was a 1-m-long structural beam in a continuous beam system of 6-m-span designed according to the Australian standards. The Global Warming Potential (GWP) and embedded energy were assessed. The results indicated that LVL beam from thinned logs presented the lowest GWP impact (5.22kg-CO2-Eq). However, due to significant energy requirements for wood drying, the embedded energy in LVL was 186.78MJ which is only marginally less than steel (216.86MJ) but significantly less than concrete (352.82MJ). LVL from mature hardwood logs had slightly higher GWP than that produced from thinning; mainly due to extra energy and materials consumption in the plantation stage. Furthermore, LVL produced from mature trees had higher embedded energy than steel.
