Data in this table are takenas neat heating value. Therefore a negative figure is obtained for manure.A recent report [lit.58] summarises the availability of biomass for energy production in theNetherlands. The gross production of biomass and organic waste in the year 2000 amounts to 222PJ (neat heating value). This total production will not show an important change in the future. In theutilisation there is a tendency that low value biological materials are used for high value applicationsas packaging or construction material. Also recycling, for example of paper and chipboard, reducesthe availability for energy production.page: 86
