Report Task leader - MANGUS 3 Project: Big>East - (EIE/07/214) 2 Introduction This document depict the assumptions, analisys and results aiming to assess the potential feedstock availability for biogas production in several European countries. In each of the target countries (Bulgaria, Croatia 1, Greece, Latvia, Romania, Slovenia) a detailed study on biomass/biogas potential was elaborated. An important part of the Big East project is based on a realistic estimation of the biogas production potential. Any policy regarding the introduction of the biogas into the energy strategy of different countries should be based on the real (reported) feedstock availability. Nevertheless, total biomass production alone (in terms of quantities) is not a strong indicator of the real biogas potential. In order to identify the categories of biomass available in each region under study, and their potential to become feedstock for biogas production, indepth insight on the agro-ecosystems material fluxes will be presented. In order to estimate the feedstock availability in each target country different feedstock sources for biogas production like waste and energy crops have been evaluated. A template including a software application (database with a help file) was created for all the partners in the project, by Mangus, in order to collect all the necessary data for the evaluation of the biogas potential based on the total biomass and biomass classes, on each area studied. In many cases the data was then extracted from Eurostat and data provided by the partners. 2.1 Aim of the study This task assesses the feedstock availability in each target country. This includes the type of feedstock (e.g. municipal and agricultural waste, energy crops, and sewage sludge) and the distribution of feedstock in each target country. The results of this task are input data for other work packages. One of the main roles of this report is also to evaluate the potential areas suitable for the development of biogas facility. The highest density biomass areas are considered the most appropriate for the development of biogas plants. The database developed in order to fulfill the task could be further improved (and used) for the identification of these areas. 2.2 Assumptions and methodology 2.2.1 Conceptual design The availability and assessment of natural resources,
