Impact on the landscape The study also examined the effects of (significantly) higher biomass production and more intensive use of biomass within the Binnenveld region. Such effects would be seen in two main areas: • An expansion of the wood stock in order to upscale production: the study assumed a fourfold increase in the stock, achieved by • Installation of local and farm-based fermenters. expanding the wooded areas alongside waterways and by planting new coppices. • A fourfold increase in the wood stock of the Binnenveld region can easily be achieved within the framework of the current Landscape Development Plan. In fact, the landscape would regain much of its original appearance. However, the authors advise against any further expansion of the wood stock beyond this level. The most important conclusion is that an intensification of biomass activities would have no negative impact on the landscape, given that: (medium-sized plants which process manure from several farms in the vicinity) are also possible in areas where the topography and distribution of buildings enable them to be readily assimilated into the landscape with no adverse impact on the quality of that landscape. 127 • Farm-based fermenters can be installed without any detrimental effect in virtually all parts of the Binnenveld region. Local fermenters Scenarios and potential contribution to local climate objectives This report presents calculations based on three alternative scenarios: 1. Basic scenario: small-scale promotion of the use of the biomass currently available, i.e. 1,500 tons of grass per annum, 48,000 tons of manure (in one local fermenter and six individual farm fermenters) and 500 tons of wood. 2. Maximum use scenario: the available volume of biomass would be maximized, resulting in a doubling of the energy production from grass, a fourfold increase in the number of farm fermenters, and a doubling of the volume of wood (to the level of annual regrowth). A calculation of the potential reduction in CO2 emissions has been made for each scenario. The results are shown in the figure below. 2.000 4.000 6.000 8.000 10.000 12.000 14.000 16.000 - basis maximizing scenario intensification 3. Intensification scenario: a fourfold increase in the wood stock, with a concomitant increase in the volume available for energy production to 4,000 tons per year. Reduction in CO2 emissions in each scenario. A relatively modest increase in the use of the available biomass flows will reduce CO2 emissions by almost 8,000 tons per year. In the maximum use scenario, the potential reduction is in excess of 12,000 tons, while the intensification scenario would account for a reduction ton CO2/year Pagina 137
