O-302 Energy consumption and CO2 emissions in the manufacture of wood tray

Abstract

The aim of this study is the assessment of energy consumption and CO2 emissions in the manufacture of wood tray. The energy consumption and CO2 emission were clarified in the manufacturing process composed of transport, sawmilling, boiling, slicing, and pressing. The energy consumption and CO2 emission per 1 kg wood tray of initial type system were 1.65MJ/kg and 0.11kg-CO2/kg for transport, 8.86MJ/kg and 0.56kg-CO2/kg for sawmilling, 26.68MJ/kg and 1.70kg-CO2/kg for boiling, 4.17MJ/kg and 0.27kg-CO2/kg for slicing, 82.62MJ/kg and 5.26kg-CO2/kg for pressing, and 123.98MJ/kg and 7.91kg-CO2/kg for total. In improved system, the energy consumption and CO2 emission were 1.23MJ/kg and 0.08kg-CO2/kg for transport, 2.43MJ/kg and 0.15kg-CO2/kg for sawmilling, 0.18MJ/kg and 0.01kg-CO2/kg for boiling, 0.58MJ/kg and 0.04kg-CO2/kg for slicing, 27.46MJ/kg and 1.75kg-CO2/kg for pressing, and 31.88MJ/kg and 2.04kg-CO2/kg for total.
