New Utilization of Boards Manufactured with Wastewood and Charcoal

Some physical characteristics as thickness swelling, heat conduction, and bending properties of composite boards made of waste wood chip and charcoal were measured. Wood-charcoal composite boards of three types and cement board were prepared for this study as shown in Table 1. Keeping duration of strawberries in the boxes(25cm x 25cm x 25cm) manufactured with the boards was also examined. Thickness swelling and bending properties(MOR and MOE) of board B and C were lower than those of board A. Among the wood-charcoal composite boards except cement board, there were no differences in heat conduction(mm/sec.). Strawberries in the box with board C were kept longer duration in fresh condition than that with cement board. From the results, it is suggested that wood-charcoal composite boards can be used for ecomaterial.
