The program to be carried out within the framework of the IEA Bioenergy Agreement consists of cooperative research, development, demonstrations and exchange of information regarding bioenergy. Within Task X Biomass Utilisation, thirteen participating countries have focused research efforts on thermal processing of biomass, biological conversion of feedstocks, processing of specialised biomass, and cross-cutting topics of interest across several technical areas. This paper addresses the various work programs and summarises the progress of Task X Biomass Utilisation during the period 1992 through 1994.
