Studies on the utilization of forest and agricultural wastes are of the extreme significance in any country where there exists a gap between the availability of, and the requirements for, livestock feeds. Forest and agriculture wastes have big potential for energetic valorization. The energetic value of these wastes in Europe is 4.5 x 10(12) MJ/y. Forest wastes are nowadays utilized as feedstock for integrated gasification processes. Therefore, there is remarkable underutilization of agricultural wastes. While waste production in the industrial sectors is usually reducing, the propensity of waste production from municipalities appears to be opposite.
