Abstract |
Degradability of landfilled wood waste is an important factor for biomethane production from solid waste landfill site. The degradability is controlled by cellulose/lignin (C/L) ratio. Test results show that the average content of cellulose in non decomposed waste wood was 40% or above and that of decomposed wood was 25%or below. Average values of cellulose/lignin ratio were measured 2.3 and 1.2 for non-decomposed and decomposed waste wood, respectively. The cellulose/lignin ratio was decreasing with the decay of landfilled wood waste. |
