초록
The contribution of forests and wood as carbon sinks reflecting the situation and conditions of each country is being highlighted. The use of wood can not only directly reduce carbon due to the storage effect, but also have an indirect effect of reducing greenhouse gas emissions by replacing carbon-intensive materials. Therefore, this study was aimed to quantify the amount of carbon dioxide emissions and to suggest suitable plans which consider the carbon emission reduction in the manufacturing process of dried domestic lumber. Since the drying process is that accounts for more than 80% of the environmental impact. The environmental benefits of improving the drying energy source were analyzed based on field data collection. Results show that the carbon dioxide emissions for sawing, drying and planing process are 34.8, 20.6, 36.2 kgCO2eq./m3 , respectively. It was decreased about 37% when the fossil fuel would be replaced with biomass fuel in drying process. Based on the results of this study, it is expected that it will be possible to activate the use of domestic wood products by establishing eco-friendliness through quantification of the greenhouse gas substitution effect of wood products and linking with related systems such as environmental labeling certification.
