Abstract
Evaluation of Biomass Availability for Biogas Production at Regional LevelCurrently available data were used in an integrated deterministic modelling approach to assess the total biomass availability. The conceptual approach of combining the benefits of relational database and GIS modelling was tested in two eastern European countries - in Latvia and Romania, both located in different bio-geographical regions. The developed system has proven its efficiency in dealing with heterogeneity in different levels of complexity regarding environmental and ecological structures. The overall approach of assessing the biomass resources was first to estimate the quantity of material generated from municipal waste and agricultural practices in each of research areas. The quantity of material that could be recovered from these practices was then taken into account and the technical and environmental constraints associated with other site factors were evaluated. As a result, the particular areas with high, medium and low potential in each country were identified.
Highlights
Considering the actual state of global needs for all forms of energy, assessing the potential of organic wastes that could be processed to obtain biogas, is one of the main tasks for a region’s successful socioeconomical development
In order to handle the heterogeneity of different studied countries, an integrated information system based on a geographical information system concept was used
The developed system was tested on different biogeographical structures presented by two European countries - Latvia and Romania - and has proven its efficiency in dealing with different levels of complexity regarding environmental and ecological structures
Summary
Considering the actual state of global needs for all forms of energy, assessing the potential of organic wastes that could be processed to obtain biogas, is one of the main tasks for a region’s successful socioeconomical development. The conceptual approach of combining the benefits of relational database and Geographical Information Systems (GIS) modelling was tested in two eastern European countries – in Latvia and Romania. This methodology was applied for biomass potential studies in the framework of the European Commission Intelligent Energy Europe program project “BiG>East”, assessing the theoretical biomass potential in six Southern and Eastern European countries. The existing methodology could be further developed in order to evaluate the technical feasibility of selected biomass; this is the task of future research and is not considered in this evaluation study
